Summary

The ci-image.yml build was failing because the DinD build environment could not resolve deb.debian.org, so apt install docker.io failed and python-repositories-ci:latest was never published. That blocked PRs using runs-on: python-repositories-ci.

  • Copy the Docker CLI from docker:27-cli instead of installing docker.io via apt (only the CLI is needed for testcontainers)
  • Add --network=host to docker build in the workflow and build-ci-image.sh so builds use the host DNS resolver

Test plan

  • Merge to main
  • Run Build CI Image (workflow_dispatch) and confirm it completes successfully
  • Verify gitea.lille-vemmelund.dk/brian/python-repositories-ci:latest exists in the registry
  • Re-run the blocked python-repositories-ci PR workflows
  • If needed, restart homelab-cluster-gitea-runner-0 to clear the DinD RWLayer error
## Summary The `ci-image.yml` build was failing because the DinD build environment could not resolve `deb.debian.org`, so `apt install docker.io` failed and `python-repositories-ci:latest` was never published. That blocked PRs using `runs-on: python-repositories-ci`. - Copy the Docker CLI from `docker:27-cli` instead of installing `docker.io` via apt (only the CLI is needed for testcontainers) - Add `--network=host` to `docker build` in the workflow and `build-ci-image.sh` so builds use the host DNS resolver ## Test plan - [ ] Merge to `main` - [ ] Run **Build CI Image** (`workflow_dispatch`) and confirm it completes successfully - [ ] Verify `gitea.lille-vemmelund.dk/brian/python-repositories-ci:latest` exists in the registry - [ ] Re-run the blocked `python-repositories-ci` PR workflows - [ ] If needed, restart `homelab-cluster-gitea-runner-0` to clear the DinD `RWLayer` error

Copy the Docker CLI from the official image instead of apt, and use
--network=host during docker build so apt and layer pulls can resolve
external registries on standalone runners.
