The Gitea Actions runners on Legion need build containers to be able
to clone repos. They run with network: host so they can't resolve
gitea.git.svc.cluster.local — they have to use the public URL. The
public URL sits behind Cloudflare Access, which is why the previous
naive switch (#3) had to be reverted.
This change keeps the runner daemon registered against the in-cluster
URL (no CF Access on the polling loop) but rewrites
http://gitea.git.svc.cluster.local:3000/ to
https://git.neuralplatform.ai/ inside the build container, with the
CF Access service-token headers injected via git extraHeader.
The redirect script is sourced before every job step via BASH_ENV;
the CF Access credentials reach the build container through
act_runner's container.env, which we now populate from the new
gitea-runner-cf-access Vault path that PR #5's Terraform writes.
Known limitation documented in the init script: actions/checkout's
per-job auth header is keyed to the in-cluster URL and gets dropped
after the insteadOf rewrite. Public repos work; private repos that
need that token will need a follow-up.
The containerd socket is mounted from the host at /run/k3s/containerd/containerd.sock
to /var/run/docker.sock inside the container, but act_runner config was pointing to
the host path directly. Fixes CrashLoopBackOff on all runner pods.
Also codifies both deployments (will org + neuron-technologies org) as git-managed
manifests so Argo CD owns them going forward.
The ExternalSecret had a stale Gitea URL (192.168.8.148:30322 — old
local IP) and runner tokens were never populated in Vault. Update the
template URL to the cluster-internal Gitea service DNS, and store the
registration tokens in Vault at secret/gitea.runner_token.
BuildKit rootless failed on k3s (mount propagation), privileged mode
fixed that but buildkitd gRPC is incompatible with the Docker REST API
that forgejo-runner needs to manage job containers. Net security change
vs. the original socket approach was zero (privileged ≈ socket access).
Remove buildkitd.yaml entirely. Restore docker-sock hostPath mount on
both runners. Builds work again.
Comprehensive runner image with Python, Node.js 20, Ruby, Go 1.22,
Docker CLI, kubectl, Helm, yq, gh, make, jq, rsync, zstd, and all
standard tools. Mirrors GitHub ubuntu-24.04 hosted runner so workflows
are swappable between Gitea and GitHub with no friction.
Add Node.js 20 LTS (required for all Forgejo JS actions), Python 3.12,
Ruby, Go 1.22, Docker CLI, kubectl, Helm, yq, gh, zstd, and common
build/system tools. Mirrors GitHub ubuntu-24.04 hosted runner capability
so jobs work without needing container: overrides for standard tasks.
Replace Alpine-based legion-runner with a minimal Ubuntu 24.04 image.
The act_runner binary is copied from the official image via multi-stage
build. Job-specific tooling (Ruby, Node, Python, etc.) belongs in
per-job container images specified via container: in workflows, not
in the base runner image.
Rename: legion-runner → ci-base
- external-secrets.yaml: GITEA_INSTANCE_URL changed from cluster-internal
URL to https://git.neuralplatform.ai so runner can register externally
- gitea.yaml: add GITEA__actions__DEFAULT_ACTIONS_URL=gitea so all
actions/* references resolve from gitea.com, not github.com
- Dockerfile: track runner image (Python 3.12 + build deps) in repo
