# Gitea Actions workflow for a single-service homelab app.
#
# THIS IS A TEMPLATE. On repo creation from this template, Gitea copies this file
# verbatim. Fill in the placeholders below (<APP>, <OWNER>, <NS>) to match your
# service. See RUNBOOK.md §2 for the one-time per-repo setup (repo secrets/vars).
#
# Proven patterns baked in (all verified live on armistace/wedding-photos):
#   - buildx driver: remote -> persistent buildkit daemon (NOT docker-container,
#     which can't reach Docker Hub on this runner). endpoint MUST be top-level,
#     not under driver-opts (that yields "no remote endpoint provided").
#   - Kubeconfig from CI secret, kubectl installed in-job.
#   - Deploy does NOT delete the namespace (preserves hand-provisioned Secrets).
#   - reconcile-cluster-inject.sh keeps the live Secret/ConfigMap in sync with
#     repo secrets/vars without clobbering hand-provisioned values.
#   - linux/amd64 only (arm64 via qemu OOMs the buildkit pod on the NUCs).
#   - Do NOT use ghcr.io images in COPY --from (buildkit can't reach it); use the
#     ECR base and install uv via pip.
