# No `options: --network host` here -- act_runner ignores that per-job
|
|
# override and always decides the job container's network from its own
|
|
# config.yaml (container.network), which defaults to an isolated
|
|
# per-job bridge. Confirmed live: with that default, DOCKER_HOST=
|
|
# tcp://localhost:2376 resolved to the job container itself, not dind,
|
|
# so every command past `docker login` (which never touches DOCKER_HOST
|
|
# -- it only talks to the registry) failed with "Cannot connect to the
|
|
# Docker daemon". host networking is set once, for every job, in the
|
|
# runner's own Helm chart.

|
# The mTLS certs dind generates at startup are a separate gap: they
|
|
# live in an emptyDir mounted into the runner/dind containers, not into
|
|
# containers a workflow spins up. Job containers get no bind mounts at
|
|
# all unless the path is in the runner's container.valid_volumes
|
|
# allowlist (empty by default -- this exact mount was rejected until
|
|
# the runner's Helm chart added a config.yaml scoping valid_volumes to
|
|
# exactly this path).

# actions/checkout@v4 is a JS action -- Forgejo Actions execs it with

|
# checkout step fails with "exec: node: executable file not found in
|
|
# $PATH" before any of the job's own steps run. Verified locally:
|
|
# `apk add --no-cache nodejs git` in this exact image gets node v22 +
|
|
# git 2.47, and the checkout action's dist/index.js then actually
|
|
# executes (confirmed by running it directly) instead of failing on a
|
|
# missing binary.
