Let's follow the steps to create more complex docker images:
- frontend - wordpress image
- backend - mysql image
First, we just start a docker images with Multipass.
PS> multipass launch docker -n kiko
Login to docker (kiko) and start creating docker-compose.yaml.
PS> multipass shell kiko
ubuntu@kiko:~$ mkdir blog && cd blog
ubuntu@kiko:~/blog$ vi docker.compose.yaml
