The docker backend's compose renderer now emits a single
`sidecars` service in place of the four per-sidecar services
when CLAUDE_BOTTLE_SIDECAR_BUNDLE is truthy. Default (unset/0/
false) keeps the legacy five-service shape so existing operators
don't have to migrate atomically; chunks 4-5 flip the default
and delete the flag.
New module claude_bottle/backend/docker/sidecar_bundle.py owns
the bundle image constant (CLAUDE_BOTTLE_SIDECAR_IMAGE env var
override + claude-bottle-sidecars:latest default), the
Dockerfile reference, the container-name helper, and the
flag-parser.
The bundle service:
- joins both internal + egress networks with aliases for every
legacy shortname + per-slug long form so the agent's
HTTPS_PROXY URL (which dials `egress` or
`claude-bottle-pipelock-<slug>`) keeps resolving with no
agent-side change
- carries CLAUDE_BOTTLE_SIDECAR_DAEMONS=<csv> for the init
supervisor to narrow which daemons to start
- carries the union of the four prior services' daemon-private
env vars (EGRESS_UPSTREAM_PROXY, SUPERVISE_*, token env names)
- does NOT carry HTTPS_PROXY/HTTP_PROXY/NO_PROXY — those would
route git-gate's git fetches through pipelock by mistake
- union'd bind-mounts at the same in-container paths as before
HTTPS_PROXY scoping moved into egress_entrypoint.sh so only
mitmdump's subprocess sees it. In the legacy four-sidecar shape
the env vars also lived in the egress service's compose env;
the shell script's export is additionally defensive.
Tests:
- All 44 existing TestCompose cases pass unchanged (flag off →
legacy shape).
- 20 new TestSidecarBundleShape cases assert on the bundle's
services / aliases / env / volumes / depends_on under the
flag.
- 8 new TestSidecarBundleFlag cases lock down the env-var
parser (unset / 0 / false / no / off → disabled; everything
else → enabled).
