In this example, we need to make nginx and php-fpm to run inside the same "pod". The reason is that we configured FPM to listen an unix socket instead of the 9000 port.

Because NGinx will need to connect to the unix socket wich is a file, both containers should share the same node and work together.

So, in the docker-compose file, we need to declare:

katenary.io/empty-dirs: socket where socket is the "volume name", this will avoid the creation of a PVC
katenary.io/same-pod: http in php container to declare that this will be added in the containers section of the http deployment

You can note that we also use configmap-volumes to declare our configuration as configMap.

Take a look on chart/same-pod directory to see the result of the katenary convert command.
