Run a Postgres Instance using Docker

.pgpass

<HOST>:5432:*:<USERNAME>:<PASSWORD>
<HOST>:5432:*:<USERNAME>:<PASSWORD>

README_FIRST.md

1. Save stack.yml to your computer
2. Copy & paste start_docker.sh into your command line to start a postgres instance
3. Set up a .pgpass file with 2 lines. One for the RDS instance and one for your local postgres instance. Put the file in your home directory
4. Copy & paste load_data.sh into your command line, to load data to your local instance. This may take 30 minutes.
5. Now you can use your docker machine's IP address at port 5432 as a hestia instance

load_data.sh

pg_dump -h <rds_host_full_uri e.g., something.amazon.com>  -U ops -C prod | psql -h <your docker machine IP e.g., 192.168.99.100>  -U postgres postgres

stack.yml

# Use postgres/example user/password credentials
version: '3.1'

services:
    db:
        image: postgres
        environment:
            POSTGRES_PASSWORD: example
        ports:
            - 5432:5432

start_docker.sh

docker stack deploy -c stack.yml

docker stack deploy -c stack.yml is not working for me, ```"docker stack deploy" requires exactly 1 argument(s).
See 'docker stack deploy --help'.

Usage: docker stack deploy [OPTIONS] STACK

Deploy a new stack or update an existing stack``` Help?
