Hey, @BrunoHigino  
I don’t know if you’re familiar with the Docker or similar technologies. But you’re running a container with an Ubuntu image which has no process defined inside. It’s just a simple shell container and waiting for a process.  
If you add the `sleep` command then you won’t see the “CrashLoopBackOff” error.  
In simple words, Kubelet is trying to achieve a running state of Pod’s container (restarting, killing, restarting …) → `kubectl describe pod <pod-name>`  
Add `sleep` command as a testing -

```auto
command:
 - /bin/sh
 - -c
 - "sleep 8999"

```
