Useful-docker-commands.md

• List all docker containers

docker container ls -a

• List port mappings or a specific mapping for the container -> see the port to your pg instance exposed from whichever db container I want to connect to

docker port <db container id>

• Remove the volumes

docker compose down -v 

• Prune the system

docker system prune -af 

• Not docker, but useful to see all open files

lsof -i 

• Show running containers

docker ps

• Shows running and stopped containers

docker ps -a

*maybe of note: docker compose down is to spin down docker-compose.yml and when you do docker compose down -v it removes volumes as it spins down..

docker compose up spin up docker-compose.yml

• remove volumes not used by a container if you forget the -v

docker volume prune

• also https://docs.docker.com/engine/reference/run/ this is a great reference spot too
