fix(plane-ce): stop forcing TLS on the Traefik ingress, and fix the WEB_URL scheme

[pratapalakshmi]

What

Ports #295 to plane-ce, which carried the same Traefik defect plus a second, worse one of its own. Also documents the nginx TLS path on both charts.

1. All three Traefik IngressRoutes no longer force TLS. charts/plane-ce/templates/ingress-traefik.yaml hardcoded HTTPS in the app route, the MinIO console route and the RabbitMQ console route — each pinned websecure and emitted its tls: block outside any conditional:

spec:
  entryPoints:
    - websecure          # never any HTTP listener
  ...
  tls:                   # outside any `if`
    secretName: {{ default (printf "%s-ssl-cert" .Release.Name) .Values.ssl.tls_secret_name }}

2. WEB_URL now follows the TLS configuration. config-secrets/app-env.yaml hardcoded it:

WEB_URL: "http://{{ .Values.ingress.appHost }}"    # regardless of ssl.*

3. New ssl.externalTermination and ingress.traefik.entryPoints, matching plane-enterprise.

Driven by the same three helpers, so each setting has exactly one job:

plane.chartManagedCert = tls_secret_name OR (generateCerts AND createIssuer)   → `tls:` block + entrypoint
plane.tlsEnabled       = chartManagedCert OR ssl.externalTermination           → https:// scheme for WEB_URL
ingress.traefik.entryPoints                                                    → entrypoint override

Chart 1.6.3 → 1.7.0. plane-enterprise 3.4.1 → 3.4.2 (docs + the nginx fix, see below).

Why

The Traefik bug is identical to #295. With shipped defaults (tls_secret_name: '', generateCerts: false, createIssuer: false) a plane-ce Traefik install was unreachable over HTTP and had no valid certificate: the routes advertised <release>-ssl-cert, which templates/certs/certs.yaml:1 only creates when createIssuer and generateCerts are both true. Traefik answers such a handshake with its built-in self-signed certificate, logs nothing, and stays Ready — which is why it went unnoticed.

The WEB_URL bug is worse than plane-enterprise's, because it hit the configurations that were working. plane-enterprise at least made WEB_URL conditional on tls_secret_name OR (generateCerts AND createIssuer). plane-ce did not: it emitted http://<appHost> unconditionally. So a plane-ce install with a perfectly good certificate served Plane over HTTPS while telling the app it lived at http:// — blocked mixed content, OAuth callbacks failing the provider's exact-match check, broken asset links. That is a live bug for every TLS-configured plane-ce user, not just the no-TLS case, and it is the one behaviour change here.

Why externalTermination is needed once WEB_URL is scheme-aware. TLS terminated upstream is invisible to the chart — an ALB with an ACM cert, an NLB TLS listener, Cloudflare, or a Traefik entrypoint with its own certificate all mean "users are on https://" while the chart owns no Secret. generateCerts: false cannot express it, being equally true of "plain HTTP, no TLS anywhere". Splitting the condition matters because "traffic is HTTPS" and "this chart owns a Secret" are different questions, and only the second may gate a tls: block.

Scope / behavior

ssl configuration	Entrypoint	tls: block	WEB_URL	vs 1.6.3
nothing set	web	—	http://	fixed (was websecure + dangling Secret)
tls_secret_name	websecure	your Secret	https://	WEB_URL fixed (was http://)
generateCerts + createIssuer	websecure	<release>-ssl-cert	https://	WEB_URL fixed (was http://)
generateCerts alone	web	—	http://	fixed (was a dangling Secret — nothing is minted without createIssuer)
externalTermination: true (4a — upstream)	web	—	https://	new
externalTermination: true + entryPoints: ['websecure'] (4b — Traefik terminates)	websecure	—	https://	new

All three IngressRoutes follow the same derivation. The nginx Ingress path already gated its tls: block and is untouched beyond picking up the WEB_URL fix.

The one behaviour change: WEB_URL moves http:// → https:// for existing TLS-configured installs, on both ingress classes. That is the bug fix, but it is a change — if you worked around the old value downstream, drop the override.

Testing

Render matrix, all three routes, release t, MinIO and RabbitMQ consoles enabled:

1  nothing set          t-ingress/minio/rabbitmq  ['web']        tls=NONE                      WEB_URL=http://   Certs=0
2  tls_secret_name      t-ingress/minio/rabbitmq  ['websecure']  tls={secretName: my-tls}      WEB_URL=https://  Certs=0
3  generateCerts+issuer t-ingress/minio/rabbitmq  ['websecure']  tls={secretName: t-ssl-cert}  WEB_URL=https://  Certs=1
4a externalTermination  t-ingress/minio/rabbitmq  ['web']        tls=NONE                      WEB_URL=https://  Certs=0
4b 4a + entryPoints     t-ingress/minio/rabbitmq  ['websecure']  tls=NONE                      WEB_URL=https://  Certs=0

generateCerts alone → ['web'], no tls:, http:// — confirming the README's "creates nothing, treated as no TLS".

Full-chart render diff against master, parsed YAML compared object-by-object with the helm.sh/chart label and render timestamp normalized out:

[nothing set]                 base=33 head=33 | differing: 2  → IngressRoute t-ingress, t-minio-ingress (the fix)
[tls_secret_name]             base=33 head=33 | differing: 1  → ConfigMap t-app-vars (WEB_URL only)
[generateCerts+createIssuer]  base=36 head=36 | differing: 1  → ConfigMap t-app-vars (WEB_URL only)
[nginx, nothing set]          base=31 head=31 | differing: 0
[nginx, tls_secret_name]      base=31 head=31 | differing: 1  → ConfigMap t-app-vars (WEB_URL only)

Textual diff for the TLS-configured case confirms the only substantive line is:

-  WEB_URL: "http://plane.example.com"
+  WEB_URL: "https://plane.example.com"

everything else being the chart-version label and the render timestamp.

Also checked: entryPoints accepts unset / [] / a list / a bare string (a scalar would otherwise render a list-less mapping the CRD rejects); helm lint passes on both charts; and every README snippet was rendered as a literal values file rather than eyeballed — including the nginx one, on both charts.

Not deployed to a live cluster. #295 got the live install → upgrade → rollback treatment on plane-eks-dev; this is the same template change plus a one-line scheme fix, verified by render diff.

Docs

plane-ce README replaces the section that documented the bug as intended behaviour — "The IngressRoute always references a TLS secret" — with the TLS options section from #295, adapted: the routing table, a copy-pasteable snippet per option, the 4a/4b split, the entrypoint override, the Traefik-redirection caveat, and an upgrade note covering both behaviour changes. ssl.externalTermination and ingress.traefik.entryPoints are added to the Ingress and SSL Setup reference table.

Both READMEs gain an nginx note. The TLS sections were Traefik-only — the table's Entrypoint column does not apply to ingressClass: nginx, and nothing said what externalTermination does there, even though an ALB or nginx-ingress holding the certificate is exactly the common nginx case.

Also fixes the nginx path outright, so that guidance describes something that renders. ingress.ingress_annotations ships commented out and templates/ingress.yaml:10 called len on it, so ingressClass: nginx died with error calling len: len of nil pointer on default values — unusable unless you happened to set an annotation. Switched to {{- with }} in both charts. Verified: both now render with annotations unset, and still emit them when set.

plane-enterprise is bumped 3.4.1 → 3.4.2 purely so the new section ships: chart-releaser runs with skip_existing: true, so a docs change under charts/ without a version bump is silently never republished.

• Supersedes fix(plane-ce): stop forcing TLS on the Traefik ingress #296. That PR did the plane-ce Traefik fix first, but it predates the CodeRabbit finding on fix(plane-enterprise): stop forcing TLS on the Traefik ingress #295 and keys plane.traefikEntryPoints on plane.tlsEnabled — carrying the routing bug where externalTermination puts the route on websecure while an upstream terminator forwards cleartext to web, so those requests 404. It also does not touch WEB_URL, and its 1.6.2 → 1.6.3 bump now collides with master. Its one unique change, the nginx len of nil pointer fix, is carried over here (and applied to both charts), so this PR is a strict superset — fix(plane-ce): stop forcing TLS on the Traefik ingress #296 can be closed.
• Follows fix(plane-enterprise): stop forcing TLS on the Traefik ingress #295 (merged), which fixed the same defect in plane-enterprise.
• feat(plane-enterprise): support OpenShift's restricted-v2 SCC and Route ingress #289 makes the same one-line nginx annotation fix to the plane-enterprise copy; expect a trivial conflict on that hunk.
• ssl.mode enum: fix(plane-enterprise): stop forcing TLS on the Traefik ingress #295 discussion concluded the boolean pair (externalTermination + entryPoints) is right for an additive change, but a single enum — none | cert-manager | existing-secret | external-upstream | external-traefik — is the better shape and would make invalid combinations like generateCerts without createIssuer unrepresentable. Wants its own PR and a major bump on both charts.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to cd62d

The nginx setup documentation should clarify that ingress.ingress_annotations: {} is a valid workaround, not only a non-empty annotation map. The change is otherwise mergeable with this bounded documentation follow-up.

Poem

A rabbit checks the TLS gate,
And hops through web at a chosen rate.
Certificates bloom when charts provide,
While HTTPS URLs safely ride.
Three routes follow the helper’s tune.
