harbor:
  # GKE counterpart of helm-overrides/k8s-admin-prd-ase1/harbor, same chart
  # (1.19.1), with one fundamental difference: this Harbor is served over
  # real TLS, and it has to be.
  #
  # The homelab runs Harbor on plain HTTP and works around containerd's
  # refusal to pull from an insecure registry by hand-editing
  # /etc/containerd/certs.d/<host>/hosts.toml on the node. GKE nodes are
  # managed and replaced, so that edit cannot survive.
  #
  # That used to mean a private CA: the registry was a nip.io name, Let's
  # Encrypt cannot issue for one (not on the public suffix list, and every
  # *.nip.io certificate shares a single rate limit), so Terraform generated
  # a CA, the node pool was told at creation to trust it for exactly that
  # hostname, and cert-manager signed Harbor from it. It worked for pulls,
  # which is what mattered, but every browser warned on the Harbor UI and
  # every docker client that was not a node needed the CA mounted by hand.
  #
  # Owning a domain removes all of it. harbor.infra.deployshed.com takes an
  # ordinary Let's Encrypt certificate that everything already trusts — the
  # nodes, dockerd in a build pod, a laptop, a browser. What retires with it:
  # registry-ca-clusterissuer.yaml, registry-ca-configmap.yaml, the CA mount
  # in every dind pod, and eventually the node pool's own
  # private_registry_access_config block in Terraform.
  #
  # The nip.io name is still served, by a standalone Ingress alongside this
  # one, and still signed by the private CA. It has to be: apps deployed
  # before the move recorded their image as harbor.35.238.248.203.nip.io/...
  # in toolshed's database, and that reference only changes when each app is
  # rebuilt. Retiring the old name before then breaks their next image pull.

  # The update strategy for the two deployments with persistent volumes,
  # jobservice and registry. Recreate, not the chart's default RollingUpdate,
  # because their volumes are standard-rwo — ReadWriteOnce — and a rolling
  # update starts the replacement pod before the old one releases the disk.
  # The new pod then waits on "Multi-Attach error for volume ... already used
  # by pod" forever, and the rollout never converges: this cluster sat in
  # exactly that state, old pods serving while new ones hung in
  # ContainerCreating. The chart's own comment on this value says to set it
  # this way when RWM volumes are unavailable.
  #
  # The cost is honest: Harbor is briefly down during an upgrade, because the
  # old pod must stop before the new one starts. That beats an update that
  # cannot complete at all.

  # are built from, which is where a stale value is noticed first.
