How do I run a container from the command line in Kubernetes (like docker run)?

Question

I would like to run a one-off container Pod from the command line in my Kubernetes cluster. I am looking for the equivalent of:

docker run --rm -it centos /b         


        

Answer 1

In order to have a Pod created instead of a Deployment and to have it removed by itself when you exit it, try this:

kubectl run curl-debug --rm -i --tty --restart=Never --image=radial/busyboxplus:curl -- /bin/sh

The --restart=Never flag is what it says to create a Pod instead of a Deployment object

Also - This image is lightweight, downloads fast and is good for network debugging.

Hope that helps
