Examples on how to build and run docker containers

General docker commands

• docker system info
• docker system events
• docker system df
• docker system prune

Space is only freed when images are deleted. Space is not freed automatically when files are deleted inside running containers. To trigger a space reclamation at any point, run the command

Diagnosing problems

1. From DockerDesktop Here
2. From CLI use the com.docker.diagnose tool probably located here: /Applications/Docker.app/Contents/MacOS/comdocker.diagnose

To create and upload diagnostics, run:

/Applications/Docker.app/Contents/MacOS/com.docker.diagnose gather -upload

After the diagnostics have finished, you should have the following output, containing your diagnostics ID:
