Postgresql: Run on Docker

So this midnight I tried to run postgresql 10 on docker. Few notes I get so far:

1. Use official image or build from official Dockerfile
2. Provide postgres password using environment variable POSTGRES_PASSWORD
3. Never forget to store in persistence volume on host, use -v /host/path/data:/var/lib/postgresql/data
4. On default config pg_hba.conf, it will use MD5 auth-method. (read for more here)
5. I can't use .pgpass if auth-method is MD5 or password
6. To use .pgpass, I need to change auth-method to trust
