Groundwork for #225, built on a throwaway pull request against the Gitea
instance rather than on assumptions. The move itself is not part of this
change - no Actions are switched off, no mirror is enabled, no branch
protection is touched.
What the probe run measured, and what follows from it:
- Which jobs need a Docker socket: only the install-test. Measured per
job - detect-changed-charts, build-chart, the quantity render and the
Trivy config scan all pass on `ubuntu-latest`, which on that instance
has no socket. The install-test dies there at "Create k3d cluster"
with "Cannot connect to the Docker daemon", an error naming k3d and
never the runner label. Its `runs-on` is now an expression: the label
`ubuntu-docker` on Gitea, `ubuntu-latest` on GitHub, because the
former does not exist there and a chart PR would otherwise queue
forever during the handover. Gitea evaluates it - the probe job was
taken by the docker runner.
- The install-test still cannot pass on Gitea. That daemon is rootless
with "Cgroup Driver: none"; the k3s node restarts immediately with an
empty log because k3s needs cgroup delegation. The label is necessary
and not sufficient, and the fix is the maintainer's.
- aquasecurity/setup-trivy cannot be used on Gitea: it checks out
aquasecurity/trivy from github.com with `github.token`, which there is
a Gitea token, and ends on "could not read Username for
https://github.com". Replaced by the release tarball - one request,
same behaviour on both forges, green on the probe run.
Also in this change:
- .github/workflows/renovate.yml, Renovate in self-operation: a daily
scheduled run in the official container, inert on github.com via a
`github.server_url` guard. Every rule proved by dry run instead of
assumed - the pinned Renovate image is tracked by the built-in
github-actions manager (44.80.0 -> 44.87.1, minor), TRIVY_VERSION is
still tracked after setup-trivy is gone (v0.72.0 -> v0.74.0, minor),
and `ubuntu-docker` is not extracted by the github-runners manager at
all, so nothing will quietly "correct" it.
- ci/migrate-issues-to-gitea.sh, runnable, with --dry-run, and NOT run.
Its header names what it cannot do: comment authorship, the #<n>
references between issues, and attachments.
- CLAUDE.md and README.md on the new flow: which forge and which tool,
auto-merge on green checks in place of the merge queue Gitea does not
have, and the measured differences of the two CIs.
Refs #225 - deliberately no "Fixes": the move is not finished with this.
