The manifest key is `egress:` now; finish the rename so the rest of the codebase matches. Files (Dockerfile.egress, claude_bottle/egress.py etc.), classes (Egress, EgressConfig, EgressRoute, EgressPlan, DockerEgress), constants (EGRESS_HOSTNAME, EGRESS_ROUTES, ...), container name prefix (claude-bottle-egress-*), docker network alias (egress), the introspection host (_egress.local), the MCP tool IDs (egress-block, list-egress-routes), and the preflight label all drop the `-proxy` suffix.

# Per-bottle egress sidecar image (PRD 0017).
|
|
#
|
|
# Replaces cred-proxy (PRD 0010). Sits on the agent's HTTP_PROXY /
|
|
# HTTPS_PROXY path (wiring lands in chunk 2) and owns three jobs:
|
|
# 1. MITM HTTPS using the per-bottle CA (chunk 2 moves the CA
|
|
# generation from pipelock).
|
|
# 2. Enforce manifest-declared path_allowlist per route.
|
|
# 3. Inject Authorization headers for routes that declare an auth
|
|
# block.
|
|
#
|
|
# Chunk 1 of PRD 0017 ships this image and the addon. Wiring it
|
|
# into the bottle launch (and the per-bottle CA + the pipelock
|
|
# upstream proxy) is chunk 2.

|
# - Upstream proxy: when EGRESS_UPSTREAM_PROXY is set,
|
|
# use mitmproxy's `--mode upstream:URL` to forward all
|
|
# post-MITM traffic through pipelock. (mitmproxy does NOT
|
|
# honor HTTPS_PROXY env vars on its outbound side — it's a
|
|
# proxy server, not a client.) Standalone runs without
|
|
# EGRESS_UPSTREAM_PROXY fall back to `regular@9099`
|
|
# direct-to-upstream — useful for unit tests of the image.
|
|
# - Upstream trust: when EGRESS_UPSTREAM_CA is set, build
|
|
# a combined trust bundle (system roots + pipelock CA) and
|
|
# point mitmproxy at it via
|
|
# `--set ssl_verify_upstream_trusted_ca`. This option REPLACES
|
|
# mitmproxy's default trust store with the file we point it
|
|
# at — passing just pipelock's CA would break pipelock-
|
|
# passthrough hosts (api.anthropic.com etc.) where mitmproxy
|
|
# sees real upstream certs signed by public CAs. The combined
|
|
# bundle covers both pipelock-MITM'd and pipelock-passthrough
|
|
# hosts.
|
|
# - -s /app/egress_addon.py → loads our addon, reads
|
|
# /etc/egress/routes.yaml.
