I'm trying to get the ip address of pods with particular label using jsonpath with the following command:
kubectl get pods -l app=validate -n {namespace_name} -o jsonpath={.status.podIP}
But this doesn't result into anything, even though the namespace and label names are correct. On the other hand, if I try to do:
kubectl get pod/pod_name -n {namespace_name} -o jsonpath={.status.podIP}
I'm able to get the pod IP address after that. But the problem is, since I'm trying to query all the pods created for a particular deployment, I want to fetch Ip addresses for all the pods under that particular label. I'm not sure what is wrong with the command.
If you have multiple Pods with the same label, you get a list of Pods. You have to adjust your jsonpath to -o jsonpath="{.items[*].status.podIP}" to get all the podIPs.
According to the official doc, you can add custom columns when querying a list of resources.
So you can do kubectl get pods -l app=validate -n {namespace_name} -o custom-columns=ip:.status.podIP
