# CD — rebuild and restart ci-ai-bot on the Pi whenever bot/ or scripts/ change.
#
# How it works (Docker-out-of-Docker):
#   1. Job runs in docker:cli on the Pi runner (eulernest label).
#   2. Mounts the HOST docker socket → builds the new image directly in the host
#      Docker daemon (no registry push needed — image is already local).
#   3. Mounts /mnt/external:ro → runs `docker compose up --force-recreate`
#      which picks up the freshly built image and recreates the container.
#
# Prerequisite (one-time):
#   - Runner config must list /var/run/docker.sock and /mnt/external in valid_volumes
#     (set in ansible-eulernest roles/gitea_runner/templates/config.yaml.j2).
#   - Set org variable JETSON_OLLAMA_URL in conformallab → Actions → Variables:
#     value = http://192.168.178.103:11434/v1
