Currently docker entrypoint is a bash script.
`docker stop` command (or restart in kubernetes) sends SIGTERM to the
container but it isn't catched by gunicorn.
So gunicorn can't start graceful shutdown which may lead to killing
user's connection and also adds 10s (default value) delay for stopping
until docker sends SIGKILL.
Using `exec` replaces the shell with the process being opened and
signals are propagated correctly.

- Used 'celery worker' command instead of 'superset worker' which is
deprecated since 0.26.0
- Used 'gunicorn' command instead of 'superset runserver'

- Improve Docker image
- smaller
- faster to build
- deterministict dependencies (see #5958)
- Rework process to simplify setting things up
- updated documentation
- less commands to type
- no files to move and modify
- optional loading of samples
- Still working in standalone mode (without volumes for superset)
This commit will try to dockerize superset in local development
environment.
The basic design is:
- Enable superset, redis and postgres service instead of using sqlite,
just want to simulate production environment settings
- Use environment variables to config various app settings. It's easy to
run and config superset to any environment if we use environment than
traditional config files
- For local development environment, we just expose postgres and redis
to local host machine thus you can connect local port via `psql` or
`redis-cli`
- Wrap start up command in a standard `docker-entrypoint.sh`, and use
`tail -f /dev/null` combined with manually `superset runserver -d` to
make sure that code error didn't cause the container to fail.
- Use volumes to share code between host and container, thus you can use
your favourite tools to modify code and your code will run in
containerized environment
- Use volumes to persistent postgres and redis data, and also
`node_modules` data.
- If we don't cache `node_modules` in docker volume, then every time
run docker build, the `node_modules` directory, will is about 500 MB
large, will be sent to docker daemon, and make the build quite slow.
- Wrap initialization commands to a single script `docker-init.sh`
After this dockerize setup, any developers who want to contribute to
superset, just follow three easy steps:
```
git clone https://github.com/apache/incubator-superset/
cd incubator-superset
cp contrib/docker/{docker-build.sh,docker-compose.yml,docker-entrypoint.sh,docker-init.sh,Dockerfile} .
cp contrib/docker/superset_config.py superset/
bash -x docker-build.sh
docker-compose up -d
docker-compose exec superset bash
bash docker-init.sh
```
