Init docker for local development environment. (#4193) 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 ``` 2018-06-10 00:26:41 -04:00			`#!/bin/bash`
