Deploy

We use docker-compose to deploy your application. You can check the docker-compose.yml and important variables in .env.example file.

There are two important variables for building production image:

  • DOCKER_FILE_INSTALL_COMMAND -- install extra packages and system requirements (ex: python3 -m pip install 'psycopg2-binary>=2.8.5' && python3 -m pip install 'Django>=3.0.6' or apt-get -y install nano)
  • DOCKER_FILE_BUILD_COMMAND -- run build static or prepare some project files for production (ex: yarn build or yarn workspace @app/_example05app build)

You can build a production docker container by docker-compose build command.

There are important variables for runtime:

  • DOCKER_COMPOSE_START_APP_COMMAND -- docker start command (ex: yarn workspace @app/_back02keystone start)
  • DOCKER_COMPOSE_COOKIE_SECRET -- the keystone important variable for sessions store (ex: AWJfbsbaf! or some secret random string)
  • DOCKER_COMPOSE_SERVER_URL -- the next.js important variable for API calls from frontend to backend (ex: https://example.dok.8iq.dev)

That's it!

You can build a production image localy and copy it to the production server by command: docker save apps:prod | bzip2 | pv | ssh [email protected] 'bunzip2 | docker load' (required brew install pv or just rm it from command)

Final script should looks like:

# 0. warm docker cache (it's speed up your rebuild)
bash ./bin/warm-docker-cache
# 1. You should build a prod image.
docker-compose build
# 2.1 Copy to prod server `docker image`
docker save apps:prod | bzip2 | pv | ssh [email protected] 'bunzip2 | docker load'
# 2.2 Copy to prod server `docker-compose.yml` and required `.env`
scp ./docker-compose.yml [email protected]:~
scp ./.env [email protected]:~
# 3. Run redeploy command
ssh [email protected] 'docker-compose down && docker-compose up -d'

NOTE: If you need some extra containers or you want to customize existing containers you can create docker-compose.override.yml file.
