feat(tls): inject centrally managed TLS config into pipelines-as-code by jkhelil · Pull Request #3385 · tektoncd/operator

jkhelil · 2026-04-30T10:41:36Z

Summary

Extends the OpenShift TLS centralization pattern to the pipelines-as-code-webhook deployment (SRVKP-9616), completing the webhook TLS trilogy alongside the Pipelines and Triggers PRs.

What changes

openshiftpipelinesascode/extension.go — switched to pointer receiver; added tektonConfigLister and resolvedTLSConfig fields. PreReconcile resolves the cluster APIServer TLS profile via ResolveCentralTLSToEnvVars. Transformers injects TLS_MIN_VERSION and TLS_CIPHER_SUITES into the pipelines-as-code-webhook deployment (pac-webhook container) when a profile is resolved.

pipelinesascode/pipelinesascode.go — EnsureOpenShiftPipelinesAsCodeExists, createOPAC, and updateOPAC now accept and propagate a platformData string parameter, stamped as the operator.tekton.dev/platform-data-hash annotation on the OpenShiftPipelinesAsCode CR. This triggers re-reconciliation when the APIServer TLS profile changes.

openshift/tektonconfig/extension.go — PostReconcile passes oe.GetPlatformData() (the APIServer TLS hash) into EnsureOpenShiftPipelinesAsCodeExists.

kubernetes/tektonconfig/extension.go — Kubernetes-side caller updated to pass "" (no platform data on Kubernetes).

extension_test.go (new) — 3 table-driven tests: no TLS config, injection into pac-webhook, no injection into unrelated deployments.

Changing the cluster APIServer TLS profile updates the hash annotation and triggers a redeploy with the new settings — same verified behavior as Pipelines and Triggers PRs.

Release Notes

On OpenShift, the `pipelines-as-code-webhook` deployment now automatically inherits the cluster-wide TLS version and cipher suites from the OpenShift APIServer TLS security profile. Changes to the profile are automatically propagated without manual intervention.

Evidence: TLS injection into PAC controller, watcher, and webhook + dynamic propagation

This comment extends the original evidence to cover the full PAC TLS scope:

pipelines-as-code-controller (pac-controller)
pipelines-as-code-watcher (pac-watcher)
pipelines-as-code-webhook (pac-webhook)

And validates the automatic propagation flow end-to-end after a fix to the InstallerSet hash computation.

1. Baseline — APIServer: Intermediate (TLSv1.2)

$ kubectl get apiserver cluster -o jsonpath='{.spec.tlsSecurityProfile.type}'
Intermediate

$ kubectl get openshiftpipelinesascode pipelines-as-code \
    -o jsonpath='{.metadata.annotations.operator\.tekton\.dev/platform-data-hash}'
d96e4890584e1fc72e863f47ee42b735054cfe7e5af8df11c1ae9d499150c129

$ kubectl get tektoninstallerset openshiftpipelinesascode-main-deployment-ldjp7 \
    -o jsonpath='{.metadata.annotations.operator\.tekton\.dev/last-applied-hash}'
952b8c90d99c31da85c8e8f1ac93bc84fff0d47c78ec06121fcdde813a062365

All three PAC deployments — TLS_MIN_VERSION=1.2, confirmed in both the InstallerSet manifests and the live Deployments:

=== pipelines-as-code-controller (pac-controller) ===
  TLS_MIN_VERSION=1.2
  TLS_CIPHER_SUITES=TLS_AES_128_GCM_SHA256,TLS_AES_256_GCM_SHA384,TLS_CHACHA20_POLY1305_SHA256,...

=== pipelines-as-code-watcher (pac-watcher) ===
  TLS_MIN_VERSION=1.2
  TLS_CIPHER_SUITES=TLS_AES_128_GCM_SHA256,TLS_AES_256_GCM_SHA384,TLS_CHACHA20_POLY1305_SHA256,...

=== pipelines-as-code-webhook (pac-webhook) ===
  TLS_MIN_VERSION=1.2
  TLS_CIPHER_SUITES=TLS_AES_128_GCM_SHA256,TLS_AES_256_GCM_SHA384,TLS_CHACHA20_POLY1305_SHA256,...

2. Switch to Old profile (TLSv1.0)

$ kubectl patch apiserver cluster --type=merge \
    -p '{"spec":{"tlsSecurityProfile":{"type":"Old","old":{}}}}'
apiserver.config.openshift.io/cluster patched

~20 seconds later, automatic propagation — no operator restart, no manual intervention:

$ kubectl get openshiftpipelinesascode pipelines-as-code \
    -o jsonpath='{.metadata.annotations.operator\.tekton\.dev/platform-data-hash}'
c44729544d9530f284d40bdab2891509f656c9f9512e06c45fa6b122daf28ec9   ← changed

$ kubectl get tektoninstallerset openshiftpipelinesascode-main-deployment-ldjp7 \
    -o jsonpath='{.metadata.annotations.operator\.tekton\.dev/last-applied-hash}'
eedb46d65fd06a9181fc1c3d01b4e80419f8687cb68dc9759a3118fd01b4ad21   ← updated

All three PAC deployments updated automatically:

=== pipelines-as-code-controller (pac-controller) ===
  TLS_MIN_VERSION=1.0   ← updated from 1.2

=== pipelines-as-code-watcher (pac-watcher) ===
  TLS_MIN_VERSION=1.0   ← updated from 1.2

=== pipelines-as-code-webhook (pac-webhook) ===
  TLS_MIN_VERSION=1.0   ← updated from 1.2

3. Restore Intermediate — reverts automatically

$ kubectl patch apiserver cluster --type=merge \
    -p '{"spec":{"tlsSecurityProfile":{"type":"Intermediate","old":null}}}'
apiserver.config.openshift.io/cluster patched

~20 seconds later:

pipelines-as-code-controller (pac-controller): TLS_MIN_VERSION=1.2   ← reverted
pipelines-as-code-watcher (pac-watcher):       TLS_MIN_VERSION=1.2   ← reverted
pipelines-as-code-webhook (pac-webhook):        TLS_MIN_VERSION=1.2   ← reverted

Summary table

Event	`platform-data-hash`	InstallerSet `last-applied-hash`	`TLS_MIN_VERSION` (all 3 PAC deployments)
Baseline (Intermediate)	`d96e4890…`	`952b8c90…`	`1.2`
After switch to Old	`c44729544…`	`eedb46d65…`	`1.0`
After restore Intermediate	`d96e4890…`	reverted	`1.2`

@jkhelil - same comment as for PR#3383 and PR#3384 related to webhook env vars. Please consider updating the var names prefixed with WEBHOOK_

anithapriyanatarajan · 2026-05-21T17:32:34Z

@jkhelil - Thank you for the update. The controller and watcher correctly have the env vars as TLS_CIPHER_SUITES and TLS_MIN_VERSION while the webhook has the values as WEBHOOK_TLS_MIN_VERSION and WEBHOOK_TLS_CIPHER_SUITES.

Could you check the ci failure for e2e tests?

theakshaypant · 2026-05-25T10:54:49Z

+	expectedHash, err := hash.Compute(struct {
+		Spec             interface{}
+		PlatformDataHash string
+	}{
+		Spec:             comp.GetSpec(),
+		PlatformDataHash: comp.GetAnnotations()[v1alpha1.PlatformDataHashKey],
+	})


Question: Why did we need to replace the usage of specHashInput here when it essentially does the same thing, with the key name being different (PlatformData -> PlatformDataHash)?

Same for other occurrences of hash calculation.

… deployment and webhook Extend the OpenShift TLS centralization pattern to the Pipelines-as-Code webhook. The openshiftpipelinesascode extension now resolves the cluster-wide APIServer TLS security profile in PreReconcile and injects the resulting TLS_MIN_VERSION and TLS_CIPHER_SUITES environment variables into the pipelines-as-code-webhook deployment (pac-webhook container) via the Transformers step. PlatformDataHashKey propagation is wired through EnsureOpenShiftPipelinesAsCodeExists / createOPAC / updateOPAC so that any change to the cluster APIServer TLS profile automatically re-reconciles the OpenShiftPipelinesAsCode CR and redeploys the webhook with the updated settings. Resolves: SRVKP-9616 Made-with: Cursor
