- ./launcher bootstrap => init seafile server data & letsencrypt, then
build a local image based on seafileorg/server:<version>
- ./launcher start => start a container using the local image
At this moment, we only support running mysql server inside the
container. Support for running mysql(and memcached) in a separate
container would be added later.
