Above, it's visible that after the deployment is created it would like to set the CPU value to 50m. But when changing the container name in the deployment, suddenly, two VerticalPodAutoscalerCheckpoint are being reported and the cpu minimum is set to 25m instead of 50, which is not correct (as it only holds one container).

Now with ".spec.resourcePolicy.containerPolicies" it's possible to address or overcome this problem. Yet it's nothing that is documented or where awareness is being raised and hence can quickly and easily trigger problems when podMinCPUMillicores is set to 50% instead of 100%

OpenShift Container Platform 4.13 and potentially before

- Always

1. See problem description

podMinCPUMillicores value is set to 50% on the respective deployment even though it has only one container and therefore should have 100% of podMinCPUMillicores set.

VerticalPodAutoscalerCheckpoint should be reconciled when the container name is changing to prevent a false image of the respective deployment (two containers but it's actually just 1)
