Bug: git fetch failed with "connect to host
claude-bottle-ssh-gate-implementer port 30009: Connection refused".
OpenSSH treats a URL-supplied port (the user's remote was
ssh://git@gitea.dideric.is:30009/...) as overriding the
~/.ssh/config Port directive, so even though the config wrote
Port 30000 the agent dialed :30009 — where nothing was listening
because the gate had been assigned BASE_LISTEN_PORT + index.
Fix: the gate's listen port now equals the upstream port. Same
script, same socat, just port = entry.Port. Two entries on the
same upstream port are rejected at prepare time (the gate is one
container with a flat port space).
Re-smoked: probe nc github.com via the gate at :22, banner came
back as expected.
PRD 0007 updated to record the design refinement.
PRD 0007: the launch ExitStack calls gate.stop on every failure
path, so an early bring-up error (where the gate container was
never created) must not raise from teardown. Mirrors the existing
DockerPipelockProxy.stop assertion.
The orphan-container enumeration in cleanup.py already covers
ssh-gate containers via its `claude-bottle-` name prefix filter —
no code change there.
PRD 0007: SSH traffic now flows through the per-agent ssh-gate
sidecar, so pipelock should know nothing about bottle.ssh.
Removed:
- pipelock_bottle_ssh_hostnames, _trusted_domains, _ip_cidrs.
- The trusted_domains / ssrf blocks built from ssh entries.
- pipelock_proxy_host_port — its last caller (the ssh provisioner)
is gone.
- is_ipv4_literal — only used to classify ssh hostnames into
trusted_domains vs ssrf.ip_allowlist, both of which are gone.
api_allowlist now derives solely from baked-in defaults +
bottle.egress.allowlist. Tests updated to pin the new shape and
assert ssh hostnames do NOT leak into pipelock's config.
PRD 0007: stop tunneling ssh through pipelock. Each Host block in
the agent's ~/.ssh/config now points at the gate container + the
per-entry listen port; HostKeyAlias preserves host-key validation
against the real upstream name, and CheckHostIP=no skips the
resolved-IP path (which would otherwise hit the gate's IP).
known_hosts collapses to a single entry per upstream keyed on the
alias.
The pipelock_proxy_host_port import is gone from this module; the
function itself becomes dead code and gets removed alongside the
broader pipelock SSH carve-outs in the next commit.
PRD 0007: thread the DockerSSHGate through the bottle lifecycle.
- DockerBottlePlan gains gate_plan: SSHGatePlan.
- prepare.resolve_plan accepts a gate and renders its entrypoint
script next to the pipelock yaml.
- launch.launch starts the gate sidecar after pipelock (so it's on
the same internal + egress networks) and registers its stop in
the ExitStack. Skipped when the bottle has no ssh entries.
- DockerBottleBackend instantiates DockerSSHGate alongside the
pipelock proxy.
- bottle_plan.print + to_dict surface the upstream table so
--dry-run shows the per-host listen-port mapping.
ssh_config provisioning still points at pipelock; that swap lands
in the next commit so this one stays a pure wiring change.
PRD 0007: Docker-specific start/stop for the SSH egress gate.
Mirrors DockerPipelockProxy: docker create on the internal
network with /bin/sh entrypoint, docker cp the staged entrypoint
script in, attach to the egress network, docker start. Image is
alpine/socat pinned by digest — self-sufficient at boot so the
gate's agent-facing leg can stay on the --internal network.
Not yet wired into the bottle launch path; that lands next.
First piece of PRD 0007: the per-agent SSH egress gate that will
let pipelock stop seeing SSH traffic. This commit only lands the
backend-agnostic surface — the SSHGate ABC, SSHGatePlan, the
listen-port assignment (BASE_LISTEN_PORT + index), and the
entrypoint-script renderer. Backend wiring lands in follow-up
commits.
The gate's agent-facing leg sits on the `--internal` network, so
the forwarder image cannot rely on apk/apt at startup. Surfaced
by the DNS spike — a placeholder using `apk add socat` died
silently and gave a false-negative DNS-on-internal result.
Spike: container on a `--internal` user-defined network resolves
another container's name via the embedded resolver at 127.0.0.11
and reaches it over TCP, while egress to the public internet
remains blocked. The PRD's design assumption holds — no design
change needed.
PRD 0006 enabled pipelock's native TLS interception, which broke
git fetch over SSH from inside the agent: pipelock's SNI gate
rejects the SSH banner that follows CONNECT. Document the
architectural fix — a dedicated per-agent TCP-forwarder sidecar
built from bottle.ssh entries — so pipelock can stay maximally
strict on the HTTPS path with no SSH carve-outs.
