We have deployed a few pods in cluster in various namespaces. I would like to inspect and identify all pod which is not in a Ready state.

 master $ k get pod/nginx1401 -n dev1401
 NAME        READY   STATUS    RESTARTS   AGE
 nginx1401   0/1     Running   0          10m

In above list, Pod are showing in Running status but having some issue. How can we find the list of those pods. Below command not showing me the desired output:

 kubectl get po -A | grep Pending Looking for pods that have yet to schedule

 kubectl get po -A | grep -v Running Looking for pods in a state other than Running     

 kubectl get pods --field-selector=status.phase=Failed
kubernetes

There is a long-standing feature request for this. The latest entry suggests

kubectl get po --all-namespaces | gawk 'match($3, /([0-9])+\/([0-9])+/, a) {if (a[1] < a[2] && $4 != "Completed") print $0}'

for finding pods that are running but not complete.

There are a lot of other suggestions in the thread that might work as well.

You can try this:

$ kubectl get po --all-namespaces -w
  • you will get an update whenever any change(create/update/delete) happened in the pod for all namespace

Or you can watch all pod by using:

$ watch -n 1 kubectl get po --all-namespaces
  • This will continuously watch all pod in any namespace in 1 seconds interval.
