test: add live migration test suite - #32
Conversation
📝 WalkthroughWalkthroughThe change adds Kind-based OLM migration E2E tests, operator lifecycle scripts, instrumented build and coverage targets, CI updates, and catalogd connectivity. Catalog queries now use catalogd URLs in-cluster or port-forwarding outside the cluster. ChangesMigration E2E testing

Could we configure this client to trust catalogd's CA? rest.InClusterConfig() loads the CA used to verify the Kubernetes API server, but the pinned OLMv1 installer gives catalogd a certificate signed by a separate olmv1-ca.
When the migration tool runs inside a pod, this appears to cause a TLS verification failure when querying catalogd. Catalog resolution then skips the failed queries and may report that the package wasn't found.
The new E2E tests run the CLI outside the cluster, so they exercise the port-forward path and wouldn't catch this. Could we also add coverage for the in-cluster path?

The in-cluster tests would be a separate effort.

do we wanna track that in a follow-up issue? @tmshort

Both event queries produce get-events.yaml; the olmv1-system events overwrite the operator namespace’s events. Include the namespace in the filenam would be better

Could we preserve the caller-provided config here? This branch ignores it whenever the process runs inside a pod, even if the caller explicitly supplied a kubeconfig for another cluster. Running inside a cluster doesn't necessarily mean that it is the target cluster, so this shortcut could cause catalog queries to fail or reach the wrong catalogd

In @.github/workflows/migration-test.yaml:
- Line 16: Update each checkout step in the workflow, including the steps using
actions/checkout@v7 at the referenced locations, to set persist-credentials to
false. Apply this consistently across all jobs without changing other checkout
behavior.
- Line 55: Increase the migration live test job timeout beyond 60 minutes so all
three operators processed sequentially by migration/test-e2e-live-matrix can
complete and the always() teardown and artifact-upload steps can run; update the
timeout-minutes setting without changing unrelated workflow behavior.
In `@migration.mk`:
- Line 70: Validate E2E_OPERATOR before the install and delete loops in the
migration targets, reusing the existing operators.sh validation when available.
Reject unknown operators, while preserving the current “all” behavior and
preventing either target from succeeding without processing an operator.
In `@migration/pkg/migration/catalog.go`:
- Around line 121-130: Update the catalog pod selection around the Lease lookup
so it never falls back to pods.Items[0]. Retry the Lease resolution until it
names a listed pod, and return an error if the request fails, has no holder, or
references an absent pod; preserve the leader matching logic in the catalog
migration flow.
- Line 93: Update the catalogd transport setup around TransportFor to avoid
inheriting Kubernetes service-account credentials: derive the client
configuration from rest.AnonymousClientConfig and configure it with the catalogd
serving CA rather than the Kubernetes API CA, while preserving the existing
transport creation flow.
- Around line 91-104: Update catalogEndpoint to prefer its supplied config
parameter when non-nil, and only call rest.InClusterConfig() when no explicit
configuration is provided. Preserve the existing endpoint, cleanup, and
catalogHTTPTransport selection behavior for both configuration sources.

rest.CopyConfig preserves the kubeconfig’s insecure-skip-tls-verify setting, and client-go rejects it together with CAData. I reproduced this locally; it prevents catalog resolution.

The catalog transport retains the kubeconfig’s proxy-url, so requests to 127.0.0.1 go through the remote proxy instead of reaching the local port-forward. The Kubernetes/SPDY connection should still use the proxy.

Adds the live OLMv0-to-OLMv1 migration E2E suite and its Kind bootstrap. The migration-test workflow runs the migration unit coverage and live-operator E2E jobs, then displays their combined coverage. Fixture scenarios are intentionally excluded from this PR.
