When booting for the first time, mysql has not properly initialized its
data. Here, we boot and stop mysql to make sure the root user has been
properly created.
We re-introduce the dependency of the nginx container on the lms/cms
images. This dependency was removed to address a debugging scenario
which is actually not practical. Without this dependency, we are forced
to use an external docker-specific resolver which makes the local nginx
configuration incompatible with the kubernetes configuration.
Portainer is no longer a global activation flag, because it does not
make much sense in the context of kubernetes. Instead, we use a simpler
"make" command.
