Kubernetes Pods, unlike Virtual Machines, don't provide a direct login capability. However, you can execute commands within a container using the command:
kubectl exec <pod-name> -- <command>
Take note that the container needs to contain the binary for the specified command, otherwise, the execution will fail. Additionally, if you have multiple namespaces, you must specify the namespace your pod is using:
kubectl exec -n <namespace name> <pod-name> -it -- /bin/sh
This will allow you to access the pod and navigate through the container. For further information, refer to the Kubernetes documentation on "Getting a shell to a running container".
