Docker

Notes

Port mapping syntax

Keep forgetting this.

${HOST_PORT}:${CONTAINER_PORT}

i.e.

8080:8000

here, 8080 is the port on the host machine and 8000 is on the docker container

Pycharm cannot find Docker on MacOS

Trying to setup docker-compose based interpreter but getting this

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I found this solution on SO. It didn't work the first time around. I restarted Docker Desktop again and also restarted Pycharm to finally get it working.
