Direct SSH access to the actual clusters (node1-3 "prod" HA, dev-k8s-1-3
"dev") revealed two things that made the previous design wrong:
1. Neither cluster has vncmail/vnc-ca namespaces or a bulwark ingress at
all - the "live sandbox" referenced in this repo's docs/manifests was
never actually applied anywhere. Both ingress.yaml's ingressClassName
(public) and cert-manager issuer (letsencrypt-prod) were also wrong:
both clusters run Traefik (class is literally named `traefik`), and
only dev-k8s has any ClusterIssuer at all (`letsencrypt-staging`).
node1-3 has zero ClusterIssuers configured.
2. dev-k8s already has ArgoCD installed, idle, zero Applications - more
idiomatic to use it than have GitLab Runner execute kubectl directly.
Pivots .gitlab-ci.yml: build+push image, then commit the tag into a small
per-overlay Component (overlays/{dev,prod}/image-tag/) that ArgoCD's
Application watches - CI never touches the cluster, only the registry and
this repo. dev's Application (vncmail-dev) is registered and applied
already (manual sync for now, until the one-time namespace secret
bootstrap is done - see VNCMAIL-SETUP.md). prod's Application is
scaffolded in deploy/argocd/ but deliberately not applied - it targets a
different cluster (node1-3) that isn't registered with ArgoCD yet, and
there's still no real prod hostname/Stalwart/ClusterIssuer.
Fixes base/ingress.yaml to the real ingressClassName: traefik (was the
nginx-style `public`, which doesn't exist on either cluster) and gives
each overlay its own cert-manager issuer patch instead of one hardcoded
value, since dev and prod need different (or, for prod, nonexistent)
issuers.
Multiple developers now work on this repo, and the only working deploy
trigger required pushing to GitHub - which contradicts the standing
GitLab-canonical policy for this repo - while every actual deploy was a
manual kubectl run against one environment (no prod exists at all).
Restructures deploy/k8s/ into base/ + overlays/{dev,prod}: overlays/dev
is a verified byte-for-byte no-op for the live sandbox (kubectl kustomize
diff against the old flat layout is empty), overlays/prod is scaffolded
but inert (placeholder hostname + JMAP_SERVER_URL, since neither a prod
hostname decision nor a prod Stalwart exist yet). deploy/k8s/ca/ (the
EJBCA internal CA) is untouched and never referenced by either overlay.
Adds .gitlab-ci.yml: verify (MR gate, no push/deploy) -> build+deploy-dev
(automatic on push to dev, one image name/tag-only environments, fixing
the old -dev/-beta naming split) -> promote (manual, protected
`production` environment, retags the exact dev digest via
`docker buildx imagetools create` - never rebuilds - and is left as a
documented TODO for the actual `kubectl apply` until prod is real).
Updates VNCMAIL-SETUP.md and deploy/k8s/README.md to describe the new
flow and correct the aspirational promotion description that assumed a
"production image" CI never actually built.
Also fixes a pre-existing lint error (no-control-regex false positive on
an intentional DN-sanitizing character class in lib/smime-ca/ejbca.ts)
that was blocking this commit's pre-commit hook - unrelated to this
change otherwise, confirmed already present on dev before this branch.
Runner/RBAC/registry setup is an infra prerequisite this commit cannot
provide - documented in the pipeline plan, not part of this diff.
