How to login/enter in kubernetes pod

Question

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?

you cannot login to a pod. it is not a process. it is a kind of 'environment'. it doesn't have port numbers. only IP. but as mentioned by others, you can exec binaries present on the node, which run as a container. — Apurva Singh, Dec 23 '22 at 21:20

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.

If your pod has many containers, you can do: `kubectl exec -n --container -it -- /bin/bash` – Andrei Manolache Apr 06 '23 at 12:54

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
