OCPBUGS-73848: test/e2e - do not use ambiguous container image short names #343

ibihim · 2026-01-14T17:25:46Z

Summary

Replace ambiguous backend image with fully qualified registry.k8s.io/e2e-test-images/agnhost:2.53
Add container args to run agnhost's HTTP server (netexec --http-port=8080)
Update test response expectations to match agnhost's output format

Problem

The e2e-component tests fail on OCP 4.22/RHEL 9 with:

ImageInspectError: short name mode is enforcing, but image name 
nginxdemos/nginx-hello:plain-text returns ambiguous list

RHEL 9 requires fully qualified container image names. The unqualified nginxdemos/nginx-hello is ambiguous since Podman cannot determine which registry to pull from.

Solution

Use registry.k8s.io/e2e-test-images/agnhost:2.53, which is the standard test image adopted across OpenShift repositories (openshift/origin PR #29672). It is fully qualified and mirrored in OpenShift CI infrastructure.

The test expectations are updated from "URI: /" to "NOW:" because agnhost's netexec returns timestamps rather than echoing the request path.

Test plan

CI e2e-component tests pass

test/e2e/proxy_test.go

 	require.NoError(t, err)

-	backendImage := "nginxdemos/nginx-hello:plain-text"
+	backendImage := "registry.k8s.io/e2e-test-images/agnhost:2.53"


Looks like the currently used version in openshift/origin is registry.k8s.io/e2e-test-images/agnhost:2.56: https://github.com/openshift/origin/blob/93a5612582f5e22a2ca64e67af649db09b6d9a9f/test/extended/util/image/image.go#L53

Should we match that?

The e2e tests fail on OCP 4.22 because RHEL 9 enforces fully qualified container image names ("short name mode"). The backend image `nginxdemos/nginx-hello:plain-text` is rejected with ImageInspectError since Podman cannot determine which registry to pull from. Replace it with `registry.k8s.io/e2e-test-images/agnhost:2.53`, a fully qualified image that is the standard e2e test image across OpenShift repositories. The agnhost image requires running the `netexec` subcommand to start its HTTP server. Update test expectations from "URI: /" to "NOW:" to match agnhost's response format. Assisted-By: Claude Code
