I want to know how I can check how many containers are currently running in my cluster? is there any command which shows me all the running containers in the cluster, not in a specific namespace. and how I can get the info about how many container per day get's run in my whole cluster?
You need to sum up all running containers in all pods. Try the following command.
kubectl get pod --all-namespaces | awk '{print $3}' | awk -F/ '{s+=$1} END {print s}'Get all pods from all namespace :
kubectl get po --all-namespacesThen you can have the number of containers in the READY column.
You can find some more info in the official doc
You can get pods by nodes and phase:
kubectl get po --all-namespaces=true --no-headers -o=custom-columns=NODE:.spec.nodeName,NAME:.metadata.name,STATUS:.status.phase --sort-by='.metadata.name'hope this helps
