 In case you need to debug what it is happening with the container you can run `docker logs <name_of_the_container>`. But if you want to get access to an interactive shell run:
 
-```
+```sh
 $ docker exec -it <name_of_the_container> /bin/bash
 ```
 
 With this same image, you can launch an interactive container with the `redis-cli` program,
 and connect to the `redis-server` that is running in the first container.

 ### Deploy with Kubernetes
 
 You can use your favorite Kubernetes distribution; if you don't have one, consider [installing MicroK8s](https://microk8s.io/).
 
 With microk8s running, enable the `dns` and `storage` add-ons:
+
 ```sh
 $ microk8s enable dns storage
 ```
