Docker Compose Nodejs and Postgres example

We can easily run the whole with only a single command:

docker compose up

Docker will pull the Postgres and Node.js images (if our machine does not have it before).

The services can be run on the background with command:

docker compose up -d

Stopping all the running containers is also simple with a single command:

docker compose down

If you need to stop and remove all containers, networks, and all images used by any service in docker-compose.yml file, use the command:

docker compose down --rmi all

Enter psql:

    psql ticketDB postgres

Show all tables

    \dt
