docker & docker-compose - Cheatsheet
Usefull commands for docker and docker-compose
| Command | Purpose |
|---|---|
| docker-compose up -d | Starts the Container and dettach (so you have your bash prompt back) |
| docker-compose down | Stops the Container |
| docker-compose ps | Checks the status of the Container |
| docker-exec -ti <container-name> /bin/bash | Opens a Shell Prompt inside a Container (so you can troubleshoot) |
| docker save <image> > file.tar | Saves an Image to a Tar file Eg.: docker save nginx:latest > nginx_backup.tar |
| docker load < file.tar | Loads a Tar file as an Image |
| docker stop $(docker ps -a -q) | Stops all Containers. You can use “rm” instead of “stop” to remove them! |
docker build --tag <tag> . | To be run from the directory where “dockerfile” lives. Will create an Image with the tag provided. Eg.: docker build –tag tornscrapper:0.1 |
docker images -a | grep none | awk '{ print $3; }' | xargs docker rmi
| Delete dangling images and / or images that have a “none” tag. Might be helpful if “docker image prune” doesn't remove those. |
