Docker / build (pull_request) Successful in 31s
This repo now lives on git.ffaerber.duckdns.org and its image is consumed by the homelab swarm, so the build moves with it: .gitea/workflows/docker.yml builds on the homelab runner and pushes to this Gitea's registry as an immutable short-SHA tag plus :latest. Build-only, on purpose. The GitHub workflow it replaces also SSHed into the Hostinger VPS and ran `docker stack deploy` on every push to main, which deploys the machine being retired and makes a deploy a side effect of a push. The homelab pattern is a PR bumping the tag in ffaerber/homelab, so shipping is a reviewed commit. Plain `docker build` rather than buildx: the runner shares the host daemon through a mounted socket, and buildx's gha cache backend does not exist outside GitHub. .github/workflows is removed from this copy so Gitea does not also try to run it -- it would log in to ghcr with a Gitea token and SSH to a host whose secrets are not here. The GitHub repository keeps its own copy untouched.
