# Flight Radar — Gitea Actions CI/CD
#
# PREREQUISITES (one-time setup — see README for full instructions):
#
#   1. Add the act_runner service to your Gitea Portainer stack.
#
#   2. Pre-create the runner config file on the host:
#      /srv/docker/traefik/stacks/gitea/volumes/act_runner/config.yaml
#      (see content in the README / deployment docs)
#
#   3. Start the runner, then grab the registration token from:
#      Gitea → Site Administration → Runners → Create Runner
#      Add ACT_RUNNER_TOKEN to Portainer stack environment variables.
#
#   4. Give the runner access to Docker (socket mounted via config.yaml).
#
# PIPELINE BEHAVIOUR:
#   • Triggers on every push to the default branch (main).
#   • Builds both Docker images on the server (no registry needed).
#   • Brings the app up with docker compose; only changed services restart.
#   • If the build fails the old containers keep running — no downtime.
#   • Prunes dangling images after a successful deploy.
