(SM) Support Tip: What's the meaning of “READY=2/2” output by command “kubectl get pods”

When running the command kubectl get pods --all-namespaces the output will show a column named READY with values such as 0/1, 1/1, 1/2, 2/2, etc. The number values show how many containers in a pod are considered ready. Some containers start faster than others or the pods readiness checks have not yet been fulfilled (or still in initial delay). In such cases there will be less containers ready in pod than the total number (ie. 1/2) hence the whole pod will not be considered ready.
