What happened:

I'd like to have a simple command to check for pods that are currently not ready

What you expected to happen:

I can see a couple of options:

• There is some magic flag I am not aware of
• Having a flag for kubectl get to filter the output using go/jsonpath
• Distinguish between Pod Phase Running&Ready and Running
• Flag to filter on ready status

How to get that currently:

kubectl get pods --all-namespaces -o json  | jq -r '.items[] | select(.status.phase != "Running" or ([ .status.conditions[] | select(.type == "Ready" and .state == false) ] | length ) == 1 ) | .metadata.namespace + "/" + .metadata.name'
