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.

# Both real clusters (node1-3 "prod", dev-k8s-1-3 "dev") run Traefik, not
|
|
# nginx — confirmed via `kubectl get ingressclass` (class is literally named
|
|
# `traefik`). Unlike nginx's restrictive 1MB default, Traefik has no default
|
|
# request-body-size cap, so there's no equivalent needed for mail attachment
|
|
# uploads (the old nginx.ingress.kubernetes.io/proxy-body-size annotation
|
|
# this file used to carry is simply not applicable here).
|
|
#
|
|
# Host, TLS secretName, and cert-manager issuer are ALL overlay-specific now
|
|
# (dev-k8s only has a `letsencrypt-staging` issuer; node1-3/prod has none
|
|
# configured yet) — every overlay's patch-ingress.yaml must override the
|
|
# CHANGEME placeholders below.
