In this PR we're adding the Garbage Collection retention spec that allows it to be set on the application.

Core PR: https://github.com/wandb/core/pull/51329

Testing:

  1. Changed wandb-dev-v2.yaml to be having the new environment variables:

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds optional W&B retention settings to API types and CRD schemas, deep-copy support, environment-resolution tests, and development manifests. It also adds release-manifest sizing and autoscaling settings, updates image tags, and changes runtime commands.

Changes

Retention configuration

Layer / File(s) Summary
Retention API and CRD contracts
api/v2/weightsandbiases_types.go, config/crd/bases/..., internal/crdinstaller/crds/operator/...
Adds optional artifact garbage-collection and data-retention fields to the API and CRD schemas. Adds application autoscaling validation to the operator CRD.
Retention copying and environment resolution
api/v2/zz_generated.deepcopy.go, internal/controller/reconciler/retention_env_test.go, hack/testing-manifests/server-manifest/.../manifest.yaml
Adds deep-copy support and tests environment-variable conversion for retention settings.
Retention development manifest
hack/testing-manifests/wandb/wandb-dev-v2.yaml
Enables artifact garbage collection, sets a 168-hour data-retention period, and updates the W&B version.

Release testing manifests

Layer / File(s) Summary
Autoscaling schema and service sizing
internal/crdinstaller/crds/operator/..., hack/testing-manifests/server-manifest/.../sizing.yaml
Adds bounded application replica settings and tiered sizing for infrastructure and application workloads.
Runtime image and command updates
hack/testing-manifests/server-manifest/.../manifest.yaml
Updates image tags, adds the runtime CA bundle path, and prepends the W&B entrypoint to the Weave cache-clear command.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 0ba43

The PR adds application retention settings and updates the associated resource definitions and manifests. It is mergeable with owner awareness that a manifest lint error should be fixed and invalid retention durations could otherwise fail later at runtime.

14-72: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add a test case for Retention == nil.

The test only covers the case where Spec.Wandb.Retention is explicitly set. Most existing WeightsAndBiases resources will not set Retention after this upgrade, since it is an optional pointer field. Add a case (or a second test function) that leaves Retention unset and asserts the expected resolved value for GORILLA_ARTIFACT_GC_ENABLED and GORILLA_DATA_RETENTION_PERIOD, since neither env var declares a defaultValue in manifest.yaml.

Reject invalid DataRetentionPeriod values at admission.

The CRD accepts any string, but metav1.Duration deserialization uses time.ParseDuration. Add an admission rule that matches the accepted duration syntax, then run make manifests generate sync-crd-embed.
