A minimal repository for exxperimenting with POSTGRESQL using Docker.

To start the container:

./scripts/create-container.sh

To begin interacting with the container:

./scripts/attach-container.sh

docker run --name example-db --mount type=bind,source="$(pwd)",dst="/code" -e POSTGRES_PASSWORD=password -d postgres

• docker run - start a container based on an image
• --name example-db- give the container a name for convenience
• --mount type=bind,source="$(pwd)",dst="/code" - connect the current working director (host machine) to the /code folder on the container
• -e POSTGRES_PASSWORD=password - give the container an environment variable
• -d - run the container behind the scenes
• postgres - the image to base it on

docker exec -it example-db psql -U postgres

• docker exec - execute a command in a running container
• -it - using an interactive terminal
• example-db - the name of the container
• psql - the command to run (psql lets you talk to POSTGRES databases)
• -U postgres - an argument to the psql command: the username
