Basic go application dockerised with a persistent postgres container

Db is created on init using the commands from the seed-data folder and will persist over stop and starts.

To interact with the db from the host machine - If you look in the docker-compose.yml you'll see that there is a port mapping that respects that postgres might be running on the host.

So to connect to to postgres container something like

         psql -h localhost -p 5433 -d postgres -U postgres -W

Fiddled around with creating a new database and a new user in the initalisation stage and couldn't seem to get it working. The db command kept getting run against the default database so settled with using the postgresdb postgres user combination.

Useful commands

        docker compose up -d
        docker compose down
        docker network prune

Rebuild

        docker compose up -d --build

Follow logs real-time:

        docker-compose logs -f
