How to get status of a particular pod or container : kubectl get pods using jsonpath
24,498
Solution 1
If you want that output, my advice would be to execute the command like this:
kubectl get pods -n kube-system some-appdeployment -o jsonpath="Name: {.metadata.name} Status: {.status.phase}"
Would this work for your case?
Solution 2
Following Command works for me, please try this out.
kubectl get pods <pod-name> --no-headers -o custom-columns=":status.phase"
Solution 3
A bit more ugly, but at least it's not the desired (as done by Javier Salmeron) but the true status of the Pod:
kubectl -n MYNAMESPACE describe pods MYPOD | grep ^Status: | head -1 | awk '{print $2}' | tr -d '\n'
Explanation: We do a describe on the Pod, then grep the row starting with Status:, strip to the first row, select the value of the 2nd column, trail the linebreak. What remains is the status value.
Solution 4
For pod status, the one and only answer (a pod can be Running but not yet ready!):
kubectl get pods -l <key=val> -o 'jsonpath={..status.conditions[?(@.type=="Ready")].status}'
For individual container statuses (need to be "true"):
kubectl get pod <pod_name> --output="jsonpath={.status.containerStatuses[*].ready}" | cut -d' ' -f2
Solution 5
kubectl get pods -n deployNamespace -ojson | jq '.spec.status.phase'
You will have jq installed.
