Remote cmd on Openshift

Do you use the graphical interface of Openshift too much ? (like way too much!) I do and I’m guilty because I know command line is always faster as soon as you got the habit. So this is it for the introduction!

Lately, I wanted to connect a pod for debugging propuse. So you can connect using the Openshift’s GUI. Or you can also use the oc command line tools.

# first use oc login and nagivate to your project
oc login <token>
oc project <project_name>

Once you are connected, you need to retrieve the pod ID. You are going to use the pod’s name to connect to the pod.

oc get pods
oc rsh <pod-name>
sh-5.1$  # session to the pods open

In my case, I had a problem with a archive file inside the pod. My only way to access was through the pod. So it’s possible to download the file in order to analyse it in your local environment.

# oc rsync <pod-name>:/<remote-dir> <local-dir> 
oc rsync <pod-name>:/data/faulty.zip /tmp
