OADP-8056: create Secret from inline CACert and use CACertRef for BSL cert rotation - #2454
Conversation
… rotation Velero upstream added CACertRef (Secret-based CA cert reference) to replace inline CACert, so a BSL's CA bundle can be rotated by updating the Secret instead of requiring the BSL object itself to change. OADP's CloudStorage-backed BSL paths only accepted inline CACert bytes on the DPA. When provided, create/own a Secret containing those bytes and set CACertRef on the resulting Velero BSL instead, giving users cert rotation support without needing to know about CACertRef. An explicit CACertRef in the DPA is passed through unchanged so users can manage their own Secret. Also updates processCACertForBSLs (the separate AWS_CA_BUNDLE ConfigMap aggregation for the Velero deployment) to resolve CACertRef in addition to inline CACert, since BSLs built through the paths above no longer carry inline CACert bytes.

- Around line 1018-1022: Update the CACertRef resolution helper used by
processCACertForBSLs to return both certificate bytes and an error. Propagate
secret lookup failures, and return an error when the referenced key is missing
unless CACertRef.Optional is explicitly true; only optional missing Secrets or
keys should return an empty result. Ensure callers handle and propagate the
returned error instead of silently continuing.
- Around line 954-955: Update the CACert-to-CACertRef transition in the BSL
reconciliation logic around the caCertRef early return to locate and delete the
obsolete generated Secret before returning, but only when its owner reference
confirms OADP ownership. Add a regression test covering the transition and
preserving Secrets not owned by OADP.
- Around line 965-966: Update the CA Secret mutation flow around the
empty-caCert deletion and inline CA update paths to require the expected DPA
controller owner reference before deleting or modifying an existing Secret.
Ensure nil-owner Secrets are never updated or deleted, reject owner collisions,
and allow creation only when the Secret does not already exist; use the existing
trusted DPA owner and collision-error handling mechanisms.

…CertRef resolution errors Addresses CodeRabbit findings on this PR: - reconcileCACertSecret now refuses to create, update, or delete a Secret at the generated name unless it already carries OADP's own label (i.e. OADP created it), instead of blindly overwriting or deleting whatever Secret happens to occupy that name. - Switching a BSL from inline CACert to an explicit CACertRef now cleans up the Secret OADP previously generated for it, instead of leaving it orphaned. - resolveCACertBytes (used by processCACertForBSLs' AWS_CA_BUNDLE aggregation) now returns an error instead of silently returning nil bytes when a required (non-optional) CACertRef can't be resolved, so a broken reference surfaces as a reconcile error rather than a BSL silently missing its CA cert. Errors for DPA-spec'd BSLs propagate and fail reconciliation; errors for extra BSLs found in-cluster but not in the DPA spec are logged and skipped instead, since one unrelated BSL's broken CACertRef shouldn't block the DPA's own ConfigMap update.

…nsumers CodeRabbit flagged that when a DPA both sets inline CACert and CACertRef (the CRD doesn't reject the combination), reconcileCACertSecret prefers CACertRef for the Velero BSL's ObjectStorage, but resolveCACertBytes preferred inline CACert for the separate AWS_CA_BUNDLE ConfigMap aggregation -- the two consumers of the same DPA fields could end up trusting different CA material. resolveCACertBytes now prefers CACertRef when set, matching reconcileCACertSecret's own precedence, falling back to inline CACert only when CACertRef is nil.

Matches Velero upstream's own deprecation of BackupStorageLocation's inline CACert field in favor of CACertRef (velero-io/velero#9141), so the CRD schema description now steers users toward CACertRef for new configs, since it supports cert rotation via a Secret update instead of requiring the BSL/DPA to change.

…BSL coverage - lib.DpaCustomResource gains BSLCacertRef, wired into BackupStorageLocationSpec() alongside the existing BSLCacert, so e2e tests can build a Velero-typed BSL with either. - cacert_suite_test.go: the minio-backed BSL scenario (Available + AWS_CA_BUNDLE + real backup/delete over the custom-CA TLS connection) now runs twice via a shared helper -- once with the legacy inline CACert (kept for backward-compat coverage) and once, as the new default, with CACertRef pointing at a user-managed Secret. The "no CACert" negative case is unchanged. - New cacert_cloudstorage_suite_test.go covers OADP-8056 itself: for a CloudStorage-backed BackupLocation with inline caCert, OADP must create an owned Secret and set caCertRef on the resulting Velero BSL instead of copying the CA bytes inline, and must delete that Secret again once the inline CACert is removed. Uses the suite's existing real cloud bucket/credentials; only asserts reconciliation and the resulting BSL/Secret state, since pointing an unrelated test CA at the real bucket's TLS endpoint isn't expected to succeed.

Verified live against a real cluster (PR#2454 installed via install-oadp-from-pr): ReconcileBackupStorageLocations requires at least one default BSL, so the single CloudStorage-backed BackupLocation in this suite must set Default: true, or DPA reconcile fails with "no default backupstoragelocations configured" and the test times out waiting for IsReconciledTrue().

Why the changes were made
Velero upstream added
CACertRef(Secret-based CA certificate reference, velero-io/velero#9141) to replace inlineCACertonBackupStorageLocation.Spec.ObjectStorage. The motivation: inlineCACertbytes are effectively cached on the BSL object — rotating a certificate requires updating the BSL itself. WithCACertRef, Velero resolves the cert from a Secret fresh on each use, so rotation is just a Secret update.OADP's DPA-level
ObjectStorageLocation/CloudStorageLocationstructs only had inlineCACert []byte, noCACertRef. This PR:CACertRef *corev1.SecretKeySelectorto both structs.CACerton a CloudStorage-backed BSL, OADP now creates/owns a Secret containing those bytes (oadp-<bsl>-cacert, keycacert) and setsCACertRefon the resulting Velero BSL, instead of copying the bytes inline — giving users cert rotation support without needing to know aboutCACertRef. If the user providesCACertRefdirectly instead, it's passed through unchanged so they can manage their own Secret.processCACertForBSLs(the separate AWS-onlyAWS_CA_BUNDLEConfigMap aggregation mounted into the Velero deployment) to resolveCACertRefin addition to inlineCACert, since BSLs built through the paths above no longer carry inlineCACertbytes — otherwise this would have silently brokenAWS_CA_BUNDLEfor CloudStorage-backed AWS BSLs using a CA cert.Fixes OADP-8056
