Is it possible to take ssh to pod? Eg: ssh pod_ip

I know we can do this with the kubectl command. But I need to do ssh from my local linux machine which doesn't have kubectl.

If you would like to login inside a particular container in the POD

kubectl exec -it <Pod_Name> -c <Container_Name> -- /bin/bash

If you would like to login to default container (or if there is only one container in POD) then just use

kubectl exec -it <Pod_Name> -- /bin/bash


PS:- If /bin/bash is not working try /bin/sh

for anyone looking for a one liner, this should do it.

Given:

  • namespace: cars
  • app: hud

Running, gets you bash in the first pod:

kubectl exec -i -t $(kubectl get pod --namespace cars --selector='app=hud' --output jsonpath='{.items[0].metadata.name}') -n cars -- /bin/bash

Where this extracts the 1st pod when listing pods:

$(kubectl get pod --namespace cars --selector='app=hud' --output jsonpath='{.items[0].metadata.name}')

I use:

kubectl exec -it deployments.apps/deployment-example bash -n namespace-example
