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.

Just like we login to docker container by "docker attach container_name" and then we can execute commands inside the container, I thought we might can into kubernetes pods as well. – solveit May 16 '21 at 14:48

yes you can ```kubectl exec -it -- /bin/sh ``` – confused genius May 16 '21 at 17:15
I was able to login to pod with command: kubectl exec -n -it /bin/sh – solveit May 18 '21 at 14:51

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.
