Description of problem:

The path used by --rotated-pod-logs to gather the rotated pod logs from /var/log/pods node folder via /api/v1/nodes/${NODE}/proxy/logs/${LOG_PATH} is only valid for regular pods but not for static pods.

The main problem is that, while normal pods have their rotated logs at this /var/log/pods/${POD_NAME}_${POD_UID_IN_API}/${CONTAINER_NAME}, static pods have them at /var/log/pods/${POD_NAME}_${CONFIG_HASH}/${CONTAINER_NAME} because the UID cannot be known at the time that the static pod is born (because static pods are created by kubelet before registering them in the kube-apiserver, and UID is assigned by the kube-apiserver).

The visible results of that are:

• Spurious errors of not found resources related to the pods.
• Rotated pod logs are not gathered even if present.

Version-Release number of selected component (if applicable):

4.10

How reproducible:

Always if there are static pods.

Steps to Reproduce:

1. oc adm inspect --rotated-pod-logs ns/openshift-etcd (or any other project with static pods).

Actual results:

• Rotated pods not gathered.
• Errors like these

  error: errors occurred while gathering data:
      one or more errors occurred while gathering pod-specific data for namespace: openshift-etcd
  
      [one or more errors occurred while gathering container data for pod etcd-master-0.example.net:
  
      the server could not find the requested resource, one or more errors occurred while gathering container data for pod etcd-master-1.example.net:
  
      the server could not find the requested resource, one or more errors occurred while gathering container data for pod etcd-master-2.example.net:
  
      the server could not find the requested resource]
  

Expected results:

No errors like the ones above and rotated pod logs to be gathered, if present.

Additional info:

Despite being marked as experimental, this --rotated-pod-logs is used in must-gather, so this issue can be easily reproduced by just running a default must-gather. I focused on bare oc adm inspect reproducers for simplicity.
