Metric-server-sample-app is being deployed on a namespace created by the patch 0001-Add-sample-app-to-metrics-server.patch named metric-server-test-app. Due to this, when metric-server-sample-app tries to use it's docker image on localhost it doesn't have the necessary permissions since default-registry-key wasn't created on this namespace. Changing the sample-app to the metrics-server namespace as to use the resources that were created when deploying metrics-server app and having authorization to use the necessary docker image to work as expected. Test Plan: PASS: Upload and apply metrics-server, apply helm overrides to set sampleApp.create=true and re-apply metrics-server. Check if sample-app pod is up and healthy. PASS: Application-update with older version with sample-app enabled Closes-Bug: 2037081 Depends-On: https://review.opendev.org/c/starlingx/metrics-server-armada-app/+/891624 Change-Id: I5dafab3410981046ab36bded7e56ee27d0124f2d Signed-off-by: Luiz Felipe Kina <LuizFelipe.EiskeKina@windriver.com>
