Quickly create a local postgres database with docker

Here are some quick package.json scripts to create, remove, start, and stop a local docker postgres database.

{
  "scripts": {
    "db:create": "docker run --name DB_NAME -e POSTGRES_PASSWORD=postgres -p DB_EXTERNAL_PORT:5432 -d postgres",
    "db:remove": "docker rm DB_NAME",
    "db:start": "docker start DB_NAME",
    "db:stop": "docker stop DB_NAME"
  }
}

Used env vars:
DB_NAME: Name for the docker container to create.
DB_EXTERNAL_PORT: What local port the database should be accessible from. Use 5432 for default pg port.

1. Might want to document the env variables to use this.
2. Install instruction for docker + postgres would help to flesh this out.
3. Link to your sources, both to give credit, and to give readers more resources.

1. Good point.
2. This is more of a cheat-sheet. This assumes you already have docker installed & know how it works. If you don't there are plenty of guides available just a search away for how to install it on your specific system. This doesn't require any psql tools to be installed, but again, it's just a search away.
3. Could you elaborate on resources? Again, this is more a cheat-sheet / quick-reference and assumes you already know what docker and pg is.
