I have kubernetes pods running as shown in command "kubectl get all -A" :
and same pods are shown in command "kubectl get pod -A" :
I want to enter/login to any of these pod (all are in Running state). How can I do that please let me know the command?
Kubernetes Pods are not Virtual Machines, so not something you typically can "log in" to.
But you might be able to execute a command in a container. e.g. with:
kubectl exec <pod-name> -- <command>
Note that your container need to contain the binary for <command>, otherwise this will fail.
See also Getting a shell to a container.
In addition to Jonas' answer above;
If you have more than one namespace, you need to specify the namespace your pod is currently using i.e kubectl exec -n <name space here> <pod-name> -it -- /bin/sh
After successfully accessing your pod, you can go ahead and navigate through your container.
