Mount sync_to_cluster bundles as K8s secrets in container tests - #5381
Conversation
Container tests (`secrets:`) treated every resolved credential as a GSM
reference and built a SecretProviderClass for it. Bundles with
sync_to_cluster: true (which includes cluster profile bundles) are
existing Kubernetes secrets, not GSM references, so this produced an
invalid SPC ("invalid mount name '' ... decodes to an empty string").
Mirror the multi-stage credentials logic: split resolved credentials
into K8s-secret references and GSM references. Copy the K8s-secret
sources into the test namespace and mount them as plain secret volumes;
only build SPCs for genuine GSM references.
The "copy a source Kubernetes secret into the test namespace" logic and
the volume-name helper were duplicated between the container-test and
multi-stage paths, so extract SourceSecretName, K8sSecretVolumeName and
CreateSourceCredentials into the shared csi_secrets package and have both
call sites use them.

📝 WalkthroughWalkthroughChangesKubernetes Secret credentials now use shared naming and copying utilities. Pod generation separates Kubernetes Secrets from GSM credentials, copies source Secrets into the test namespace, mounts them as regular Secret volumes, and omits SecretProviderClass resources for them.

- Around line 22-30: Update SourceSecretName and K8sSecretVolumeName to use a
deterministic, injective, bounded naming scheme that keeps distinct
namespace/name pairs separate while satisfying Kubernetes Secret and volume-name
limits. Ensure generated volume names remain DNS-1123 compliant and preserve
compatibility between copied Secrets and their pod references. Add tests
covering collision resistance and maximum-length inputs.
In `@pkg/steps/pod.go`:
- Around line 496-501: Update the container-test GSM documentation to explain
that bundles with sync_to_cluster: true, including cluster profile bundles,
resolve to existing Kubernetes Secrets and use the legacy secret-mount path
without creating a SecretProviderClass; retain the CSI/direct-GSM guidance only
for applicable bundle references.

Container tests (the
secrets:field) were treating every GSM bundle as a CSI-mounted secret, but bundles markedsync_to_cluster: trueare already synced to the cluster as normal Kubernetes secrets and must be mounted that way instead. Because of this, any container test that referenced such a bundle failed withinvalid mount name ''. This change makes container tests handle those bundles the same way multi-stage tests already do: copy the existing Kubernetes secret into the test namespace and mount it as a plain secret volume, and only build a CSI SecretProviderClass for real GSM references. This also covers cluster profile secrets, since those are defined assync_to_cluster: truebundles too.This is relevant only for bundles (in
gsm-config.yaml) that havesync_to_cluster: true:Example container-test
secrets:stanza that now works:Follow-up after #5372
https://redhat.atlassian.net/browse/DPTP-5187
Summary
Container tests now treat
sync_to_cluster: truebundles as Kubernetes Secrets. The tests copy source Secrets into the test namespace and mount them as plain Secret volumes.The pod setup creates CSI
SecretProviderClassresources only for genuine GSM credentials. This preventsinvalid mount name ''failures and supports cluster profile Secrets.Shared Secret-copying and volume-name logic now serves both container-test and multi-stage workflows. Tests verify copied Kubernetes Secrets, standard volume mounts, and the absence of unnecessary CSI resources.
