- Resolve #1893
- Add syslogd to output sshd log on stdout (via `docker logs`)
- Enforce directory rights on `/data/git`, `/data/gogs` & `/data/ssh`
- Add `SOCAT_LINK` environment variable to prevent the creation of scout links when they are not needed (see #1815)

- Remove port 80 & 443 unused by the container
- Add port 3000 used by gogs application

- `start.sh` will now verify that the port is not already used by another service
- Resolve #1807
- Log when a service is created, or could not be created
- Keep track of which port is already used, including goes & sshd port

- ssh/setup: test directive now check if a file exist in key path instead of a folder
- ssh/setup script was hanging waiting for an input about rewriting the key
  as the test case was returning true, when it should have been false
  (check if file is a folder instead of a file)

- resolve #1765
- create link to old git repository path: `/home/git/gogs-repository`

- Volumed subfolder now created up in the ENTRYPOINT script, this way
  they are created before S6 even starts making VOLUME.
- The subfolder will be created during VOLUME creation too as ENTRYPOINT
  script will be run before /bin/true
- SSH Keys will now be created on a single key basis not replying on the
  existence of /data/ssh folder

- Fix s6 fifodir error on container restart
- Add .tags* to .gitignore (Atom auto ctags generation)

- Now using a setup script before starting the app. The separation of
the run script and the setup script will make service initialisation a
little bit clearer
- Now calling start.sh script as ENTRYPOINT and S6 as CMD. This way
when running the container with just a shell script, the start.sh
script will be launched before, making debugging easier
- Added note about `.dockerignore` ignored during Docker Hub Automated
Build

- Removed unnecessary variables
- Fixed symbolic links creation
- Fixed enter point
- Less intermediate containers

- VOLUME for ‘/data’
- Usage of S6 as PID 1 Process
- Usage of ‘socat’ so linked container (like databases) are binded to
localhost
- OpenSSH, Socat Link and Gogs are supervised using S6
- Size of container reduced to ~75Mo

Shrink docker image.
Update from fig (deprecated) to docker-compose.
Update README.md.

The previous setting would cause all repo creations to fail, as
described in issue #328.
The previous commit also resolves this issue, but it seems saner to
create the user in the Dockerfile than at runtime.

Why not use the environment variables, when they are there...

The dev Dockerfile now works without superfluous go get calls.
At this point the -u option is really not what we want.

Rewrite of the docker setup. Now uses fig to manage containers and container
linkage. The base is a block based mix and match, which will give you the
possibility to easily test all configurations.
