I do feel this is important :
kubectl get pods --all-namespaces --field-selector status.phase!=Running
will give you info about pods that not running but not if allication in it is ready…
so you add readiness probe
How quickly I can get info about readiness failure on all pods ?
as of now the only way is to go over events like :
k get events | grep ‘Readiness probe failed*’
new question : is k events go over all namespaces or not ?
