# Recreate (not RollingUpdate): the gitea data volume is a single RWO PVC. With
# RollingUpdate the new pod tries to attach the PVC while the old pod still holds
# it -> "Multi-Attach error", new pod stuck Init forever, rollout wedged. Recreate
# terminates the old pod first so the PVC detaches before the new one starts.

# External SSH access for git over the LAN. The chart's ssh Service becomes a
# LoadBalancer with a stable IP from the Cilium homelab-pool (192.168.1.160/28,
# L2-announced) so `git clone ssh://[email protected]:2222/...` works from the
# LAN. gitea's sshd listens on 2222 in-pod; port 2222 is exposed directly to
# avoid needing privileged :22.

    # Actions must be enabled globally, not just per-repo. Without this section
    # app.ini carries no [actions] block at all and Forgejo never *creates* a
    # workflow run — the API returns total_count: 0 for every repo even though
    # each repo reports has_actions: true, the workflow file is on the default
    # branch, and forgejo-runner has registered successfully with label
    # [docker]. Registration does not require the dispatcher, so a healthy-
    # looking runner sitting at "[poller 0] launched" with zero task pickups is
    # the symptom of this being off, not of a bad workflow or a label mismatch.
    #
    # DEFAULT_ACTIONS_URL is left at its default (https://code.forgejo.org),

    # requires egress from the runner; if it is ever blocked, pin the actions to
    # local copies rather than turning this off.
