didericis-claude 01cee056be feat(secrets): encrypt egress tokens at rest with per-bottle ENV_VAR_SECRET

test / unit (push) Successful in 48s
Update Quality Badges / update-badges (push) Failing after 52s

lint / lint (push) Successful in 2m31s
Implements the interim secret-provider design (PRD prd-new-secret-provider):
each agent receives a random ENV_VAR_SECRET injected into its container env
at launch. The host uses this key to encrypt each egress auth token value
(HMAC-SHA256 CTR mode, stdlib-only) and store it in a new
bottled_agent_secrets table (one row per env var, key column plaintext for
auditing). The key never touches the DB.

On infra container restart the in-memory token map is lost. launch_consolidated
now calls _reprovision_running_bottles after ensure_running: for each
registered bottle still alive on the gateway network it execs
`printenv ENV_VAR_SECRET` into the agent container and posts the result to the
new POST /bottles/<id>/reprovision_gateway control-plane endpoint, which
decrypts the stored rows and restores _tokens — no manual intervention needed.

@@ -75,88 +75,6 @@ On compatible macOS hosts, the default backend requires Apple's `container` CLI
Use `BOT_BOTTLE_BACKEND=docker ./cli.py start <agent>` on hosts where neither Apple Container nor KVM is available and Docker is the desired backend.
### Containers inside a bottle
A bottle may set `nested_containers: true`. On the macOS backend this starts a
guest-local, rootless **podman** service after the bottle is registered and
exposes its Docker-compatible API socket, so the agent still runs `docker` and
`docker compose`. Nothing is mounted from the host: Docker Desktop's socket
stays out of the bottle and the guest gains no outer VM capabilities. Backends
that cannot do this (`docker`, `firecracker`) reject the flag rather than
silently ignore it.
Rootless Docker was tried first and does not work here at all: Apple
Container's capability bounding set omits `CAP_SYS_ADMIN`, which the kernel
requires to write a multi-range `uid_map`. See
[`docs/research/rootless-docker-in-apple-container-spike.md`](docs/research/rootless-docker-in-apple-container-spike.md).
The tradeoff to understand before enabling it: podman avoids that requirement
by falling back to a single-UID mapping, so nested containers provide **no
isolation from the agent itself** — `root` inside a nested container is the
agent user outside it. Nested containers are a build/test convenience, not a
security boundary. The bottle remains the boundary.
Pulling images goes through the bottle's egress proxy like every other
request, so each registry needs a route — **and so does the CDN it redirects
layer blobs to**, which is a different host. Without the CDN route the pull
authenticates, fetches the manifest, then 403s partway through.
Docker Hub and GHCR additionally need `preserve_auth: true`: their token dance
uses a client-fetched per-scope bearer token that the proxy would otherwise
strip. Turn DLP off on every registry and CDN route — the bodies are
compressed layer blobs that no detector can read, and buffering them is what
triggers the shared-proxy OOM in #455.
```yaml
nested_containers: true
egress:
routes:
# Docker Hub: registry, token endpoint, blob CDN.
- host: registry-1.docker.io
preserve_auth: true
dlp: { outbound_detectors: false, inbound_detectors: false }
- host: auth.docker.io
preserve_auth: true

# GHCR: registry + blob CDN.
- host: ghcr.io
preserve_auth: true
dlp: { outbound_detectors: false, inbound_detectors: false }
- host: pkg-containers.githubusercontent.com
dlp: { outbound_detectors: false, inbound_detectors: false }
# quay.io: registry + blob CDNs. No preserve_auth needed for public pulls.
- host: quay.io
dlp: { outbound_detectors: false, inbound_detectors: false }
- host: cdn01.quay.io
dlp: { outbound_detectors: false, inbound_detectors: false }
- host: cdn02.quay.io
dlp: { outbound_detectors: false, inbound_detectors: false }
- host: cdn03.quay.io
dlp: { outbound_detectors: false, inbound_detectors: false }
```
`mcr.microsoft.com` and `registry.k8s.io` follow the same shape and also
redirect blobs elsewhere (`*.data.mcr.microsoft.com` and
`us-*-docker.pkg.dev` respectively); route whichever host the 403 names.
Inside a nested container the same allowlist applies: an allowlisted host
returns 200 and anything else gets a 403 straight from the proxy. The
gateway's CA bundle and proxy settings are wired in automatically, so
`docker run … curl https://…` works with no extra flags — no `--add-host`,
`-e`, or `-v`.
Two things worth knowing when testing that:
- Public DNS inside a nested container fails **by design**. Everything
egresses through the proxy, so `nslookup` failing is expected and is not
evidence of a problem.
- Alpine's BusyBox `wget` drops the connection after the proxy's TLS
interception and reports `error getting response`, even though the proxy
logs the decrypted request and returns a response. Use `curl` to test
egress; BusyBox `wget` will lie to you.

"""Guest-local container engine for Apple-container bottles (issue #392).
The service and every nested container remain inside the existing per-bottle
VM. This module refuses to compensate for missing prerequisites with outer
capabilities, a privileged container, or a host Docker socket.
Podman is used rather than rootless Docker for one specific reason: Apple
Container's capability bounding set omits `CAP_SYS_ADMIN`, which the kernel
requires to write a multi-range `uid_map` via `newuidmap`. Rootless Docker
has no path that avoids that write. Podman does with no subordinate UID
range configured it falls back to a single-UID self-mapping, which an
unprivileged process may write itself. See
`docs/research/rootless-docker-in-apple-container-spike.md`.
That fallback is why `build_image` *removes* the agent user's `/etc/subuid`
and `/etc/subgid` entries instead of adding them: their presence is precisely
what would send podman down the `newuidmap` path that cannot work here.
The agent still talks to `docker` and `docker compose`; those speak to
podman's Docker-compatible API socket, so nothing in the agent's habits
changes.

The test workflow lives at [`.gitea/workflows/test.yml`](../.gitea/workflows/test.yml).
It runs the unit suite plus one integration job per backend
(`integration-docker`, `integration-firecracker`) on:
It runs `tests/run_tests.py` (full suite — unit + integration) on:
- every push to a branch with an open pull request, and
- every push to `main`.
Each integration job selects its backend via `BOT_BOTTLE_BACKEND` and
runs a **preflight** (`./cli.py backend status --backend=<name>`) that
prints a clear per-check readiness summary and fails the job when the
backend is missing — so absent infrastructure is visible at the job level
rather than hidden among per-test `unittest.skip` lines. The skip guards in
[`tests/_backend.py`](../tests/_backend.py) gate on the same readiness
check (`bot_bottle.backend.has_backend`): backend-agnostic tests use
`skip_unless_selected_backend_available()` and run through whichever
backend is selected (checking, e.g., Linux + `/dev/kvm` for Firecracker
rather than unrelated Docker availability); Docker-implementation tests use
`skip_unless_backend("docker")` and no-op under a non-Docker run.
Integration tests need Docker on the runner; they skip cleanly via
`tests/_docker.skip_unless_docker` when no daemon is reachable.
A small subset of integration tests skip when running specifically

# PRD prd-new: Containers inside a bottle
- **Status:** Draft
- **Author:** Claude
- **Created:** 2026-07-21
- **Issue:** #392
## Summary
Let an agent run `docker` and `docker compose` *inside* its bottle by starting
a guest-local rootless podman service that exposes a Docker-compatible API
socket. Gated per bottle by `nested_containers: true`. No host daemon socket is
mounted and no capability is added to the guest, on any backend.
## Problem
Agent tasks routinely involve containers: `docker compose up` to verify a
scaffolded stack, a throwaway database for a test run, building an image to
check a Dockerfile works. Bottles have no way to do any of that, so those tasks
either fail or get done outside the bottle — which defeats the point of the
bottle.
## Goals / success criteria
- A bottle with `nested_containers: true` on the `macos-container` backend can
run `docker compose up -d --wait` against a stock compose file, pulling from
a routed registry and serving from the workspace.
- The agent's habits do not change: `docker` and `docker compose`, not
`podman`.
- No host Docker socket is mounted, on any backend.
- No capability is added to the Apple Container guest.
- Backends without a guest-local engine reject the flag with a clear error
rather than ignoring it.
- Bottles that do not set the flag carry none of its cost.
## Non-goals
- Nested containers as an isolation layer. The single-UID mapping means `root`
inside a nested container is the agent user outside it. This is for build and
test workloads; the bottle stays the security boundary.
- The `docker` and `firecracker` backends. Both reject the flag for now.
- Reaching registries that are not routed through the bottle's egress proxy.
## Design
### Why podman, not rootless Docker
Apple Container's capability bounding set omits `CAP_SYS_ADMIN`, which the
kernel requires in order to write a multi-range `uid_map` via `newuidmap`.
Rootless Docker has no path that avoids that write, so it cannot run in a
bottle without granting `CAP_SYS_ADMIN` — which is close to root in practical
terms and gives up most of what the bottle is for.
Podman does have a path: with **no** subordinate UID range configured it falls
back to a single-UID self-mapping, which an unprivileged process may write
itself. The image build therefore *removes* the agent user's `/etc/subuid` and
`/etc/subgid` entries rather than adding them — their presence is exactly what
would send podman down the `newuidmap` path. Full negative result in
[`docs/research/rootless-docker-in-apple-container-spike.md`](../research/rootless-docker-in-apple-container-spike.md).
### The flag, and its name
The flag is kept because it gates real costs, not because podman needs a
privilege grant: ~100MB of derived image, a resident service per bottle, and
relaxed modes on `/dev/fuse` and `/dev/net/tun` that the majority of bottles
should not get.
It is named `nested_containers`, not `docker_access`. It implies no Docker and
grants access to nothing on the host — naming it after Docker access would
describe the one thing the design refuses to do.
### Shape
- `bot_bottle/backend/macos_container/nested_containers.py` — derived-image
build, guest env, device preparation, service start/readiness.
- `bot_bottle/backend/macos_container/nested-containers-init.sh` — the
unprivileged bootstrap that runs inside the bottle. Fails closed on every
prerequisite it needs (podman, the storage/network helpers, writable device
nodes, an *empty* subordinate range) rather than degrading.
- The derived image `…-nested-containers` layers the Docker CLI, the compose
plugin, and podman 5's networking stack — `passt` (pasta), `netavark`,
`nftables`, `aardvark-dns` — plus `fuse-overlayfs`, `slirp4netns`, and
`uidmap` onto the agent image. Podman itself already ships in every built-in
image (#451), but with `--no-install-recommends`, so none of the networking
pieces arrive with it. Each absence fails at a different and misleading
layer: no pasta and nothing starts; no `nft` and containers are created but
never start; no aardvark-dns and DNS inside a container fails while
everything else looks healthy. Image pulls keep working throughout, which is
what makes these read as compat-API bugs.
- `BottleBackend.supports_nested_containers` — false by default, so a backend
that cannot honor the flag fails in the shared `prepare` template.
Guest configuration the single-UID mapping forces:
`ignore_chown_errors` (no second UID for layers to be chowned to),
`cgroups="disabled"` and `cgroup_manager="cgroupfs"` (no cgroup delegation
reaches the guest), `events_logger="file"` (no journald socket).
### Registry reach
Image pulls egress through the bottle's proxy like everything else, so each
registry needs a route — **and so does the CDN it redirects blobs to**, which
is a separate host: `production.cloudfront.docker.com` for Docker Hub,
`pkg-containers.githubusercontent.com` for GHCR, `cdn0*.quay.io` for quay.
Without those the pull authenticates, fetches the manifest, and then 403s
partway through. Docker Hub and GHCR need `preserve_auth: true` — their
token dance uses a client-fetched per-scope bearer token that the proxy would
otherwise strip. Layer pulls should also set `dlp.outbound_detectors: false`
and `dlp.inbound_detectors: false`: body scanning on a multi-hundred-MB layer
is what triggers #455, and a registry route's scanned bodies are compressed
layer blobs rather than anything a detector can read.
### Reaching the network from a nested container
Public DNS inside a nested container fails by design: everything egresses
through the proxy. What was actually broken was reaching the proxy at all, and
it took four attempts to fix because podman applies proxy settings at several
layers and the last writer wins:
| Layer | Applies to |
|---|---|
| `~/.docker/config.json` proxies block | **every container the Docker CLI starts** — client-side, beats everything below |
| service environment | podman's own pulls, non-CLI API clients |
| `containers.conf` `env` | native `podman run` |
| `containers.conf` `hosts_file`, `http_proxy` | native `podman run` only — the compat API ignores both |
The gateway is named `bot-bottle-gateway`, which resolves only through the
bottle's `/etc/hosts`; a nested container gets its own. Since no config key
reaches the compat path, the name is resolved in the bottle and the *address*
is substituted into the proxy URL at each layer above. `NO_PROXY` keeps the
name, which is matched against what a client asks for.
The gateway TLS-intercepts, so the CA bundle is mounted read-only and
`SSL_CERT_FILE`, `CURL_CA_BUNDLE`, `REQUESTS_CA_BUNDLE`, and
`NODE_EXTRA_CA_CERTS` point at it — no distro-specific trust commands.
## Verified on macOS 26 / Apple Container 1.0.0 / podman 5.4.2
With plain `docker`, no extra flags: image pulls from Docker Hub, GHCR, and
quay; `docker run` with correct exit-code propagation; `docker compose` up,
logs, down, and a published port curl'd from the bottle; `curl https://quay.io`
and `https://pypi.org/simple/` returning 200 from inside a nested container;
and `https://example.com` returning **403** — the egress allowlist applies to
nested containers, not just the bottle.
Alpine's BusyBox `wget` drops the connection after TLS interception and
reports "error getting response". The proxy logs the decrypted request, and
`curl` on the same host succeeds, so this is a BusyBox client limitation
rather than anything in the egress path.
## Open questions
- Whether the `docker` and `firecracker` backends want an equivalent, or
whether guest-local containers stay macOS-only.

# PRD prd-new: Encrypted at-rest egress secrets (SecretProvider, interim slice)
- **Status:** Draft
- **Author:** didericis
- **Created:** 2026-07-21
- **Issue:** #355
## Summary
An interim step toward the generic `SecretProvider` (#355) that stops short
of per-request minting. Today the orchestrator holds each bottle's egress
auth tokens **in process memory only**, so any infra-container recreation
silently strips every already-running bottle of its upstream credentials.
This PRD makes those secrets survive a gateway restart by persisting them
**encrypted**, under a key that is not itself sitting next to the
ciphertext.
The end state in #355 — short-lived, scoped credentials minted per request
— removes the need to store anything durable at all. That is a larger
change gated on per-upstream minting support. This slice buys back
restart-survivability now without regressing to plaintext secrets at rest.
## Problem
`Orchestrator._tokens` (`bot_bottle/orchestrator/service.py:74-79`) is a
plain in-memory dict, deliberately never written to the registry DB:
> Held **in memory only** — never written to the registry DB — so the
> gateway can inject each bottle's upstream credential without secrets at
> rest. Lost on restart (re-launch re-registers them); the future
> SecretProvider (#355) replaces this with per-request minting.
The registry itself *is* durable (SQLite on a container-only volume), and
so is the gateway CA since #450 / `2cd44cf7`. The tokens are now the only
piece of gateway state that does not survive a restart, which makes the
failure mode both silent and confusing.
### Observed failure
Checking out a branch that touches `bot_bottle/**/*.py` changes
`source_hash()` (`bot_bottle/orchestrator/lifecycle.py:88-99`).
`MacosInfraService._source_current()`
(`bot_bottle/backend/macos_container/infra.py:159-169`) sees the mismatch
and `ensure_running()` force-removes and recreates the infra container
(`infra.py:198-208`). The registry rows survive on the DB volume; the CA
survives on its host bind-mount; `_tokens` comes back empty.
Every already-running bottle then fails closed, mid-session, on its next
outbound request:
- `/resolve` succeeds — the bottle is still `active` in
`orchestrator_bottles` and its policy blob is served intact, including
`- host: "api.anthropic.com"` with `auth_scheme: Bearer` /
`token_env: EGRESS_TOKEN_0`.
- `tokens_for()` returns `{}`, so the resolved env overlay has no
`EGRESS_TOKEN_0`.
- `decide()` (`bot_bottle/egress_addon_core.py:644-652`) blocks with
`egress: route for 'api.anthropic.com' declared auth but env var
'EGRESS_TOKEN_0' is unset` — an 89-byte `403` on every request.
Confirmed live on the macOS backend on 2026-07-21: two bottles running
since 20:29/20:30 were still registered `active` with valid policy after
the 23:05 infra recreation, and both took 89-byte `403`s from then on,
while a bottle launched *after* the recreation egressed normally. The
recovery today is to relaunch every affected bottle.
Note this is a re-attachment blocker distinct from #443/#445 and from #450
— the CA and the gateway address were both fine. It is specifically the
credential wipe.
## Goals / Success criteria
1. A bottle's egress auth tokens survive infra-container recreation: an
already-running bottle keeps egressing across a gateway restart with no
relaunch and no operator action.
2. Secrets are **never** at rest in plaintext, and never at rest next to a
key that trivially decrypts them.
3. Compromise of the registry DB file alone does not yield usable
upstream credentials.
4. The stored form is revocable and rotatable without relaunching bottles
that are not affected.
5. When the retained bottle record reaches the lifecycle status `removed`,
its stored secrets are destroyed. Status/event persistence and the removal
transition land separately; this interim slice intentionally retains the
ciphertext across today's teardown/reconcile calls until that lifecycle is
available.
6. Migration is transparent: existing bottles keep working, no manifest
changes required.
## Non-goals
- **Per-request minting** of short-lived scoped credentials. That is the
#355 end state; this PRD is explicitly the interim slice and should not
foreclose it.
- Generalizing `DeployKeyProvisioner` into the full `SecretProvider` ABC,
or the manifest-level `{ provider: <name> }` reference surface.
- User-extensible provider discovery (`~/.bot-bottle/contrib/<name>/`).
- Changing the `/resolve` contract's shape (it already carries `tokens`).
- Fixing the *trigger*`source_hash` churn on branch switch. Recreating
infra is legitimate; it just must not cost running bottles their
credentials. A separate guard that refuses recreation while bottles are
active is complementary and out of scope here.
## Design
> **TODO (didericis):** the encryption flow goes here — key custody, where
> the key material lives relative to the ciphertext, the wrap/unwrap path
> at register and at `/resolve`, and what an attacker who holds only the
> DB (or only the host, or only the infra container) can recover.
Constraints the design has to satisfy, for reference while drafting:
- The gateway's `PolicyResolver` needs the cleartext at request time, on
the data-plane path, so unwrap has to be cheap enough to sit in a
per-flow `/resolve` (or be cached in memory after first unwrap).
- The infra container is recreated routinely and unattended. Anything
requiring an interactive unlock on every recreation defeats the goal.
- The DB lives on a container-only volume that the host does not mount, so
host-side and guest-side components see different filesystems — that
asymmetry is available as a place to split custody.
- The agent must never be able to reach the key material. It is a separate
container with no control-plane token, which is the existing boundary.
## Open questions
- Where does the unwrap key live, and what recreates/re-derives it when the
infra container is rebuilt?
- Is the cleartext cached in memory after first unwrap, or unwrapped per
request? (Latency vs. exposure window.)
- What is the rotation story — re-wrap in place, or force re-registration?
- Does this land behind a flag, or replace `_tokens` outright?

# Egress proxy OOMs on large downloads
Found on 2026-07-21 while running the rootless-podman spike
(`docs/research/rootless-docker-in-apple-container-spike.md`). Recorded
rather than fixed — the fix is a security-relevant decision, not a
mechanical patch.
## Summary
A single large HTTPS download through the gateway kills the egress
proxy. `mitmdump` buffers whole response bodies so the DLP detectors can
scan them, grows past the gateway container's memory limit, and is
OOM-killed by the cgroup. Nothing restarts it.
Two properties make this worse than a failed download:
- **The gateway is a per-host singleton.** Every bottle shares it, so
one bottle's download takes egress away from all of them.
- **There is no restart on death.** The gateway supervisor is
`while : ; do wait ; done`; a killed daemon stays dead until the infra
container is recreated.
So ordinary agent activity — pulling a container image, downloading a
model or dataset, fetching a large tarball — is a denial of service
against every other bottle on the host. No malice required, though it is
trivially reachable on purpose.
## Evidence
Triggered by `docker compose up` pulling `quay.io/fedora/python-312`
(two layers, ~82MB and ~83MB) inside a bottle. The pull itself
succeeded; the *next* request failed:
```
initializing source docker://quay.io/fedora/python-312:latest:
pinging container registry quay.io: Get "https://quay.io/v2/":
proxyconnect tcp: dial tcp 192.168.128.39:9099: connect: connection refused
```
From the gateway's `dmesg`:
```
python3 invoked oom-killer: gfp_mask=0x100cca(GFP_HIGHUSER_MOVABLE), order=0
oom-kill:constraint=CONSTRAINT_MEMCG,
oom_memcg=/container/bot-bottle-mac-infra,
task_memcg=/container/bot-bottle-mac-infra,task=mitmdump,pid=118
Memory cgroup out of memory: Killed process 118 (mitmdump)
total-vm:1391936kB, anon-rss:997768kB
```
~1GB RSS against a 1024MB container. Note the amplification: ~165MB of
layers produced ~1GB of resident memory, so the buffering is several
copies deep (encoded body, decoded body, and the text conversion the
regex detectors scan).
Afterwards the gateway container was still running and healthy-looking —
orchestrator, supervise, and git-http all alive — with no `mitmdump`
process at all, and it stayed that way until the container was
recreated. A liveness check on the container would not have caught this.
## Reproduction
1. Launch any bottle with an egress route to a host serving a large file.
2. Download >~150MB over HTTPS through the proxy.
3. `dmesg | grep -i oom` inside `bot-bottle-mac-infra`, and note that no
`mitmdump` process remains.
Beware a false negative when checking: truncating the process listing
(`cut -c1-45`) cuts before the binary name, because `mitmdump` runs as
`/usr/local/bin/python3.12 /usr/local/bin/mitmdump …`.
## Fix options, not yet chosen
1. **Restart dead daemons.** Smallest change and strictly an
improvement: an OOM then degrades one download instead of removing
egress for every bottle. Does not stop the OOM.
2. **Cap the scanned body size.** Above a threshold, stop buffering —
either skip the scan or stream it. This is the root-cause fix and a
security decision: a size threshold is exactly the hole an exfiltrator
would aim for, so "skip above N" trades a DoS for a covert channel.
Streaming with a bounded window keeps coverage, at more complexity.
3. **Raise the gateway's memory limit.** Moves the threshold; does not
remove it.
Worth noting that (1) and (2) are complementary — the restart gap is
worth closing regardless of how the memory behaviour is resolved.

# Firecracker Image Remote Store
**Date:** 2026-07-22
**Context:** PR #459 (run-dir leak fix) surfaced that committed Firecracker snapshots
currently live only on the host machine. Once a host is wiped or a run-dir is
evicted, a user's preserved bottle is gone. This note investigates a secure remote
store so committed images survive host turnover and can be restored without the
user having to pre-flag which sessions to keep.
## Verdict
Backblaze B2 + Cloudflare CDN is the cost-optimal choice for most deployments.
Cloudflare R2 is the simpler zero-config option at slightly higher storage cost.
Self-hosted MinIO is the right call for air-gapped or on-premises installs.
On the image-size front, zstd-compressing the committed tar before upload
produces roughly a 6070% reduction with negligible impact on restore latency.
OverlayFS (for in-flight working rootfs, not for the committed artifact) cuts
per-instance disk use to ~1050 MB per extra bottle sharing the same base.
---
## What Gets Stored
The Firecracker backend produces two artifact types:
| Artifact | Created by | Size | Lifetime |
|----------|-----------|------|---------|
| `rootfs/agent-<digest>/` (dir) | `image_builder.py``mke2fs -d` | ~1 GB as ext4 | Cached per Dockerfile hash; evictable |
| `committed/<slug>/rootfs.tar` | `FirecrackerFreezer._freeze` via SSH tar | 500 MB1 GB | User-preserved; must survive host wipe |
The committed artifact is a tar of the guest's live filesystem streamed out over
SSH (`freezer.py:5890`). At resume time `launch.py` calls `mke2fs -d` to
rebuild a fresh ext4 from this tar. The tar — not the ext4 — is what needs to be
pushed to remote storage and pulled back at restore time.
The base image cache (`rootfs/agent-<digest>/`) is derivable from the Dockerfile
and can be rebuilt on demand; it is lower priority for remote storage.
---
## Storage Candidates
### Object storage
| Provider | Storage | Egress | Notes |
|----------|---------|--------|-------|
| **Backblaze B2** | $0.006/GB | Free (via Cloudflare Bandwidth Alliance) | Cheapest storage; pairs with Cloudflare CDN to eliminate egress |
| **Cloudflare R2** | $0.015/GB | $0 always | Zero-config egress; no lifecycle transitions (limitation) |
| **Wasabi** | $0.0069/GB | Free (1:1 ratio) | 90-day minimum retention; good for archival; lifecycle evaluated daily |
| **AWS S3** | $0.023/GB | $0.09/GB | Richest lifecycle support; expensive at scale; avoid unless already in AWS |
| **MinIO** (self-hosted) | Host cost only | None | S3-compatible; best for private/on-prem deployments |
**B2 + Cloudflare CDN** is effectively $0.006/GB with zero egress — about 18×
cheaper than S3 for restore-heavy workloads. **R2** is the zero-config choice
($0 egress by default, no Bandwidth Alliance pairing needed) at a slightly
higher storage rate.
**Cloudflare R2's missing lifecycle support** is the main caveat: auto-eviction
rules (evict images older than N days) cannot currently be expressed natively in
R2. Wasabi and S3 both support declarative lifecycle policies.
### Retention policy recommendation
The comment proposes:
- Retain images for ~1 week by default
- Warn when approaching a capacity threshold
- Auto-evict oldest images once threshold is exceeded
This maps cleanly to an application-level policy (not a provider lifecycle rule),
which avoids the R2 limitation and works consistently across providers:
1. On `commit`: upload tar, record `(slug, size_bytes, uploaded_at)` in a local
or remote manifest file.
2. On startup / on `list`: scan the manifest, warn if total stored size exceeds
e.g. 80% of the configured threshold.
3. On eviction run (CLI or cron): delete objects older than `retention_days`
(default 7) that push total over `max_capacity`; oldest-first.
This keeps the policy logic in bot-bottle and the storage provider as a dumb
object store — no vendor-specific lifecycle API required.
---
## Image Size Reduction
### Current artifact sizes
A typical committed tar for a Claude Code agent image is 500 MB1 GB uncompressed.
The per-run ext4 (copy of the base, written at `start`) adds another ~1 GB of
local disk. The leak fix in this PR addresses the ext4 copies; the remote store
addresses the committed tars.
### Compression
zstd compression of the committed tar before upload is the highest-leverage
single change:
| Codec | Typical size (1 GB rootfs) | Compress speed | Decompress speed |
|-------|---------------------------|---------------|-----------------|
| gzip | 350430 MB | ~100 MB/s | ~500 MB/s |
| **zstd (default)** | **330360 MB** | **~400 MB/s** | **~2 GB/s** |
| xz | 290320 MB | ~20 MB/s | ~200 MB/s |
**zstd is the best trade-off**: 6567% size reduction, near-instantaneous
decompression. The `tar` call in `freezer.py` could pipe through `zstd` before
writing to disk and to the remote; `resume` decompresses on the way back. A
`.tar.zst` suffix marks compressed artifacts so old tars remain restorable
without the codec.
### SquashFS for the base image cache
The `rootfs/agent-<digest>/` directory (the buildah-exported tree) is rebuilt by
`image_builder.py` and turned into per-run ext4 by `mke2fs -d`. Storing the
base as a SquashFS image instead of a flat directory tree would reduce it from
~1 GB to ~330360 MB and make the cache remote-friendly. Firecracker does not
directly boot SquashFS, but the existing `mke2fs -d` path reads a directory tree
— a SquashFS mount could serve as the source. This is a larger change and lower
priority than tar compression.
### OverlayFS for per-run rootfs
Multiple simultaneous bottles sharing the same agent image today each get a full
`mke2fs -d` copy (~1 GB). OverlayFS (read-only base + writable sparse overlay)
would reduce this to ~1050 MB per instance beyond the first:
- Mount the base image directory as read-only lower layer
- Attach a sparse ext4 or tmpfs writable layer per bottle
- Pass the merged overlay to Firecracker as the block device
E2B's public write-up on Firecracker + OverlayFS confirms this approach works
at scale. The `launch.py` changes would be non-trivial (device mapper or
`fuse-overlayfs` plumbing), so this is a follow-up rather than a prerequisite
for the remote store.
---
## Recommended Approach
**Phase 1 — remote store with zstd (tight scope, actionable now)**
1. Add `--zstd` to the `tar` call in `FirecrackerFreezer._freeze`; name the
artifact `rootfs.tar.zst`. Keep uncompressed restore path for legacy tars.
2. Add a `bb firecracker upload <slug>` / `bb firecracker pull <slug>` pair that
pushes/fetches the compressed tar to the configured object store (S3-compatible
API, so B2, R2, MinIO, and Wasabi all work with the same client).
3. Store a `manifest.json` in the bucket (or a local mirror) tracking slug →
`{size, uploaded_at}`. Use it for threshold warnings and eviction.
4. Default retention: 7 days, configurable via `firecracker.image_retention_days`
in `~/.config/bot-bottle/config.toml` (or equivalent).
5. Warn at 80% of `max_capacity` (default e.g. 50 GB); evict oldest on commit
once at 100%.
**Storage recommendation:** Cloudflare R2 for hosted deployments (zero egress,
zero config), MinIO for private/on-premises.
**Phase 2 — base image cache compression**
Compress the `agent-<digest>` cache dir as a `.tar.zst` to save ~65% on repeated
image uploads. Low urgency since the base image is rebuildable.
**Phase 3 — OverlayFS per-run disk**
Replace the full per-run ext4 copy with an OverlayFS sparse layer. Largest disk
impact (~9095% savings per concurrent bottle) but highest implementation
complexity. Track as a separate PRD.
---
## Open Questions
- Does the host have a configured object-store credential path, or should the
remote store be an opt-in with an explicit `bb config set image-store.url ...`?
- Should `commit` automatically upload, or should upload be an explicit step to
avoid surprise egress?
- What is the acceptable cold-start latency for a restore from remote? A 330 MB
zstd tar at 100 Mbit/s takes ~26 s; at 1 Gbit/s, ~2.6 s. This bounds the
retention strategy (evict from local after successful upload vs keep local copy).

# Rootless Docker inside Apple Container bottles
Spike branch: `spike/rootless-docker-macos` (`a4d8461`)
**Outcome:** the podman recommendation below shipped as the
`nested_containers` bottle flag — see
[`docs/prds/prd-new-nested-containers.md`](../prds/prd-new-nested-containers.md).
The `docker_access` name used throughout the spike text was renamed on the
way in; it granted no access to anything on the host.
## Summary
**Negative result.** Rootless Docker cannot run inside an Apple
Container bottle without granting the bottle `CAP_SYS_ADMIN`. This is a
kernel constraint on writing multi-range `uid_map`, not a packaging gap
we can close with a better init script, a different base image, or more
careful `/etc/subuid` handling.
The spike was built on the premise — stated in
`bot_bottle/backend/macos_container/rootless_docker.py` — that it would
*"deliberately refuse to compensate for missing prerequisites with outer
capabilities, a privileged container, or a host Docker socket."* That
premise is exactly what the experiment falsified. The two ways forward
are to abandon the premise (add `CAP_SYS_ADMIN` to the bottle, and with
it most of the isolation the bottle exists to provide) or to abandon
rootless Docker.
Recommendation: abandon rootless Docker. Podman does not have this
problem — see [Podman is not blocked by
this](#podman-is-not-blocked-by-this) below.
## Local environment
Tested on 2026-07-21:
```console
$ sw_vers
ProductName: macOS
ProductVersion: 26.5.1
BuildVersion: 25F80
$ container --version
container CLI version 1.0.0 (build: release, commit: ee848e3)

```
## The failure
`tests/integration/test_macos_rootless_docker_spike.py` builds the
image, launches the bottle, and dies in `rootless_docker.start`:
```
+ exec rootlesskit --net=slirp4netns --mtu=65520 ... dockerd-rootless.sh
[rootlesskit:parent] error: failed to setup UID/GID map:
newuidmap 1100 [0 1000 1 1 100000 65536] failed:
newuidmap: write to uid_map failed: Operation not permitted
```
## Why it fails
Every prerequisite you would normally suspect is present and correct in
the guest:
| Check | Result |
| --- | --- |
| `/usr/bin/newuidmap` | `-rwsr-xr-x root root` — setuid bit intact, survived the OCI export |
| `/` mount options | `rw,relatime`**not** `nosuid` |
| `NoNewPrivs` | `0` |
| `Seccomp` | `0`, no filters |
| `/etc/subuid`, `/etc/subgid` | `node:100000:65536` in both |
| user namespace | `user:[4026531837]`, identical to pid 1 — the *initial* userns |
| `unshare -U -r true` | succeeds |
| `/proc/sys/user/max_user_namespaces` | `4505` |
The one thing that is missing is in the capability bounding set that
Apple Container gives the container:
```
CapBnd: 00000000a80425fb
= chown, dac_override, fowner, fsetid, kill, setgid, setuid, setpcap,
net_bind_service, net_raw, sys_chroot, mknod, audit_write, setfcap
```
No `CAP_SYS_ADMIN`. That is the whole story, and the chain is:
1. The kernel's `map_write()` gates writing a `uid_map` on
`file_ns_capable(file, ns, CAP_SYS_ADMIN)` — capability over the
**new** user namespace, evaluated against the credentials that opened
`/proc/<pid>/uid_map`.
2. `newuidmap` is setuid-root, so it runs with euid 0 — but its
capability sets are clamped by the bounding set, which has no
`CAP_SYS_ADMIN`.
3. `cap_capable()` has a shortcut that grants *all* capabilities when
the caller's userns is the new namespace's parent **and**
`ns->owner == cred->euid`. It does not apply: the namespace was
created by `node` (uid 1000) while `newuidmap` runs as euid 0.
4. So the check falls through to the effective-set test in the initial
userns, which fails. `EPERM`.
Note that the single-line unprivileged path (`unshare -U -r`) works
precisely because it does not go through `newuidmap` and does not need
`CAP_SYS_ADMIN`. Only the multi-range subuid mapping that rootless
Docker requires does.
This is the same constraint that makes upstream's `dind-rootless` image
require `--privileged`. It is not specific to Apple Container, except
that Apple Container gives us no bounding set that includes
`CAP_SYS_ADMIN` by default.
## It does work with the capability — which is the point
Adding the capability clears the failure immediately, and exposes one
further, much smaller blocker: `/dev/net/tun` exists (the kernel has
tun; `/proc/misc` lists `200 tun`) but Apple Container creates it
`crw------- root root`, so uid 1000 cannot open it and `slirp4netns`
fails with `open: Permission denied`. A `chmod 0666 /dev/net/tun` as
root inside the bottle fixes that, and needs no capability beyond what
the bottle already has.
With both applied by hand, the daemon comes up completely:
```console
$ container run --rm -u root --cap-add CAP_SYS_ADMIN \
bot-bottle-claude:latest-rootless-docker sh -c '...'
Server Version: 20.10.24+dfsg1
Storage Driver: fuse-overlayfs
Cgroup Driver: none
Cgroup Version: 2
API listen on /tmp/rt/docker.sock
```
So `rootless-docker-init.sh` and `rootless_docker.py` are *correct*.
The spike did not fail on a bug. It failed on its own premise.
Two secondary findings from that run, relevant if anyone revisits this:
- Debian's `docker.io` package pins Docker **20.10** (EOL), not the 28.x
implied by the `docker:28-cli` compose plugin the image copies in.
- `Cgroup Driver: none` — no resource limits on nested containers.
## Why we should not just add the capability
`CAP_SYS_ADMIN` is close to a superset of "root" in practical terms —
mount, `pivot_root`, namespace manipulation, and a long tail of
subsystem-specific powers. Granting it to the agent bottle would
undercut the containment argument the rest of the backend is built
around, including the deliberately narrow choices immediately adjacent
to it in `launch.py` (`--cap-drop CAP_NET_RAW`, no `NET_ADMIN`, a
host-only agent network). Trading all of that for nested `docker
compose` is a bad exchange.
## Podman is not blocked by this
Sanity-checked on the same host, same kernel, same runtime, so the
comparison is apples to apples:
| Scenario | Result |
| --- | --- |
| Podman rootless, `/etc/subuid` populated | **Fails identically**`newuidmap: write to uid_map failed: Operation not permitted` |
| Podman rootless, no subuid ranges, `--network=host` | **Works**, no added capabilities |
| Podman rootless, no subuid ranges, default netns, `/dev/net/tun` at `0600` | Fails — `slirp4netns: open("/dev/net/tun"): Permission denied` |
| Podman rootless, no subuid ranges, default netns, `/dev/net/tun` at `0666` | **Works**, no added capabilities |
The difference is that podman degrades gracefully when no subuid range
is available: it falls back to a single-UID self-mapping, which an
unprivileged process may write itself, so `newuidmap` is never invoked
and `CAP_SYS_ADMIN` is never needed. Docker's rootless mode has no
equivalent fallback.
The cost of that fallback is real and should be weighed before building
on it: with a single-UID mapping, every UID inside a nested container
collapses onto the bottle's own uid 1000. There is no UID separation
between the agent and anything it runs — `root` in a nested container is
the agent user outside it. It also requires `ignore_chown_errors` on the
storage driver. Whether that is acceptable depends on whether the bottle
boundary (which is unchanged) or the nested-container boundary (which is
effectively nil) is the one we are relying on.
## What the podman spike then needed
The podman implementation that replaced the Docker one on this branch
turned up two more device-node blockers of the same shape as
`/dev/net/tun` — Apple Container creates the node, but 0600 root:root:
- **`/dev/fuse`** — blocks the `fuse-overlayfs` storage driver
(`fuse: failed to open /dev/fuse: Permission denied`). Without it the
only working driver is `vfs`, which copies whole layers per container.
- **`/dev/net/tun`** — blocks `slirp4netns`, which rootless podman uses
for the default bridge network.
Both are fixed by `chmod 0666` as root inside the bottle, which needs no
capability the bottle does not already hold. This is categorically
different from the `CAP_SYS_ADMIN` requirement: it is a permission on a
node that already exists, not an outer privilege grant.
One design note worth recording: the agent-facing surface stays `docker`
and `docker compose`, pointed at podman's Docker-compatible API socket
via `DOCKER_HOST`. Setting `netns="host"` in `containers.conf` does *not*
propagate through that compat API — stock `docker run` and compose files
request bridge networking explicitly — so slirp4netns (and therefore the
`/dev/net/tun` chmod) is required for ordinary compose files to work at
all. Host networking remains available per-workload via
`--network=host`.
Verified working in a bottle with zero added capabilities: fuse-overlayfs
storage, the compat API socket, `docker run` on both bridge and host
networking, and published ports.
### Nested pulls collide with our own egress DLP
The first live run got podman up and `docker compose` running, then
failed on the image pull:
```
web Pulling
initializing source docker://python:3.12-alpine: reading manifest ...
StatusCode: 403, egress DLP: Generic Bearer JWT found in body
```
This is bot-bottle's own egress scanner, not a podman problem. The
Docker registry auth flow carries a bearer JWT *by protocol*, and the
`token_patterns` detector's `Generic Bearer JWT` rule
(`Bearer\s+[A-Za-z0-9._\-]{50,}`) matches it on every pull. Any bottle
that pulls images will hit this.
The fix is per-route detector scoping, which the egress config already
supports — drop `token_patterns` on the registry hosts and keep
`known_secrets`:
```json
{"host": "registry-1.docker.io",
"dlp": {"outbound_detectors": ["known_secrets"]}}
```
That is the right trade rather than a grudging one: `known_secrets`
matches the bottle's *actual* credential values, so real exfil through a
registry host is still caught. `token_patterns` on a registry route only
ever produces protocol noise.
Worth generalising later: any manifest enabling `nested_containers` needs
this on its registry routes, so it probably belongs in a shared
registry-route snippet rather than being copy-pasted per bottle.
### And then registry auth collides with the Authorization strip
With DLP scoped, the pull failed differently: `unauthorized:
authentication required`. This one is architectural.
`egress_addon.py` strips agent-set `Authorization` unconditionally
before forwarding — deliberately, so an agent cannot smuggle a
credential out in a header the DLP detectors don't recognise. A route
may carry gateway-injected auth instead, but only from a *static* token
in an env var (`auth_scheme` + `token_env`).
Docker registry auth doesn't fit that shape. The client fetches a
short-lived, per-repository-scope bearer token from `auth.docker.io` and
presents it to `registry-1.docker.io`. There is no static token to
inject, and the token the client legitimately obtained is stripped.
Measured inside a bottle, by hand:
| Step | Result |
| --- | --- |
| Fetch token from `auth.docker.io` | 200, 5409-byte token body |
| Manifest request **with** that valid token | 401 |
| Manifest request with **no** Authorization | 401 — identical |
A valid token behaves exactly like sending none, which is direct
evidence the header never arrives. Any nested-container workflow that
pulls from a registry is blocked on this, so it is not a detail that can
be deferred: pulling base images is most of what nested containers are
for.
### Registries that skip the token dance work today
Not every registry needs the stripped header. Measured directly:
| Registry | Manifest request with no `Authorization` |
| --- | --- |
| `quay.io` | 200 |
| `mcr.microsoft.com` | 200 |
| `registry.k8s.io` | 307 (redirect, no auth) |
| `ghcr.io` | 401 |
| `registry-1.docker.io` | 401 |
So "just add the registry to the bottle config" genuinely works — for
quay, MCR, registry.k8s.io, or any unauthenticated internal registry.
Docker Hub and GHCR are the ones that need the strip resolved. The
acceptance test uses quay for exactly this reason.
Resolving it for Docker Hub means picking one of:
1. **Per-route opt-in to preserve client Authorization.** Smallest
change. Note the compounding effect on exactly these routes: the DLP
scoping above already removed `token_patterns` there, so a
preserved-auth registry route is one where the agent may send bearer
tokens that neither the strip nor the pattern detector inspects.
`known_secrets` still applies, so the bottle's real credentials are
still caught.
2. **A registry-aware gateway** that performs the token dance itself and
injects the result. Preserves the invariant fully; materially more
work, and it makes the gateway speak a specific registry protocol.
3. **Pre-seed images at provision time** (host-side `container image
save` into podman storage), so bottles never pull at runtime.
Preserves the invariant, and limits nested containers to
pre-approved images — which fits the custody positioning, at the cost
of no ad-hoc `docker pull`.
4. **Stop.** Nested containers are not supported on this backend.
### Podman 4.3.1 silently swallows container exit codes
Debian bookworm — which the current agent base image is built on —
ships podman 4.3.1. Through its Docker-compatible API, `docker run`
returns 0 no matter what the container did:
| Command | podman 4.3.1 | podman 5.4.2 |
| --- | --- | --- |
| `docker run … sh -c 'exit 7'` (compat API) | **0** | 7 |
| `docker run … sh -c 'exit 0'` (compat API) | 0 | 0 |
| `podman run … sh -c 'exit 7'` (native) | 7 | 7 |
This is worse than a broken feature: every failing command an agent runs
via `docker run` reports success. A test suite, a build step, or a CI
script inside a bottle would pass while failing. It also silently
defeated the acceptance test's egress-containment assertion, which is
why that assertion now checks an in-band marker rather than an exit
code.
Podman 5.4.2 (Debian trixie) fixes it, but needs two packages that
bookworm's podman does not: `passt` (podman 5's default network tool)
and `nftables` (netavark shells out to `nft`; without it every run fails
with `unable to upgrade to tcp, received 500`). With both installed,
exit codes propagate correctly and the compat API behaves.
The open question this leaves is where podman 5 comes from, since the
agent base is bookworm-based:
1. **Move the agent images to Debian trixie.** Trixie is current stable.
Correct, and the blast radius is every bottle, not just this feature.
2. **Drop the compat socket and use podman natively** (`podman-docker`
provides a `docker` shim; compose comes from `podman-compose`).
Native podman propagates exit codes correctly even on 4.3.1. Contained
to this feature, at the cost of `docker compose` becoming
`docker-compose`/`podman-compose`.
3. **Ship bookworm's podman 4.3.1 with the compat socket** — not viable.
Silent false success is a correctness bug agents cannot see.
## Recommendation
1. Do not revive rootless Docker on this backend. This document is the
record of why.
2. Nested containers, if wanted, come from podman under the
single-mapping constraint — with the explicit understanding that the
nested-container boundary carries no security weight. `root` in a
nested container is the agent user outside it.
3. Nested containers are therefore a build/test convenience. The bottle
remains the security boundary, exactly as it was.

Each CI integration job runs `./cli.py backend status --backend=<name>`
