Examples connecting to PostgreSQL

We got our own image called 'my-postgres-db'. We can run it as a container by doing:
docker run -d --name my-postgresdb-container -p 5432:5432 my-postgres-db

To enter the container:
docker exec -it postgres-docker bash

• exec we’ve entered a postgres-docker image
• -it in detached mode
• bash to run its bash app

You need to use the following connection details to connect to the DB:

• Host: localhost
• Port: 5432
• User: postgres
• Password: docker (from Dockerfile)
• Database name: usershop (from Dockerfile)

To see the images:
docker images -a

To remove images:
docker image rm 'nameOfTheImage'
