How to get PID of the main process in containers to be used for strace

Hwo to get PID of the main process in a container used later on to check strace. Needed for CKS Kubernetes certification.

kubectl get pod -n team-tulip \
  -o custom-columns="P:.metadata.name,N:.spec.nodeName,ID:.status.containerStatuses[0].containerID" \
  --no-headers \
  | awk -F" " '{
      print "ssh " $2 " -- sudo strace -p $(ssh " $2 " -- sudo crictl inspect " substr($3,14,14) " | yq .info.pid)" "# " $1
    }'

controlplane:~$ kubectl get pod -n kube-system  -o custom-columns="ID :.status.containerStatuses[0].containerID,P:.metadata.name,N:.spec.nodeName" --no-headers | \ 
awk '{print "ssh "$3 " -- sudo crictl inspect " substr($1,14,14) " | \
yq '.info.pid' # " $2}'
