* fix: use bash shebang for wider compatibility
* fix: quote the command subst to prevent word splitting
- Add a shell script to orchestrate a production setup with
`docker-compose`. The script fetches config and `docker-compose.yml`
from the `master` branch, generates a secure password, performs DB
migrations and starts the container services.
- Add a health check for Postgres container service in `docker-compose.yml`.
- Add cusotm `container_name` for services inside `docker-compose`.
This is helpful to check the status of containers in the install shell script.
