| ### CONTAINERS ### | |
| docker stop $(docker ps -a -q) #stop ALL containers | |
| docker rm -f $(docker ps -a -q) # remove ALL containers | |
| docker rm -f $(sudo docker ps --before="container_id_here" -q) # can also filter | |
| # exec into container | |
| docker exec -it $(docker container ls | grep '<seach_term>' | awk '{print $1}') sh | |
| # exec into container on windows with Git Bash | |
| winpty docker exec -it $(docker container ls | grep '<seach_term>' | awk '{print $1}') sh | |
| # helps with error: 'unexpected end of JSON input' | |
| docker rm -f $(docker ps -a -q) # Remove all in one command with --force | |
| docker exec -i -t "container_name_here" /bin/bash # Go to container command line | |
| # to exit above use 'ctrl p', 'ctrl q' (don't exit or it will be in exited state) | |
| docker rm $(docker ps -q -f status=exited) # remove all exited containers | |
| ### IMAGES ### | |
| # list images and containers | |
| docker images | grep "search_term_here" | |
| # remove image(s) (must remove associated containers first) | |
| docker rmi -f image_id_here # remove image(s) | |
| docker rmi -f $(docker images -q) # remove ALL images!!! | |
| docker rmi -f $(docker images | grep "^<none>" | awk '{print $3}') # remove all <none> images | |
| docker rmi -f $(docker images | grep 'search_term_here' | awk '{print $1}') # i.e. 2 days ago | |
| docker rmi -f $(docker images | grep 'search_1\|search_2' | awk '{print $1}') | |
| ### DELETE BOTH IMAGES AND CONTAINERS ### | |
| docker images && docker ps -a | |
| # stop and remove containers and associated images with common grep search term | |
| docker ps -a --no-trunc | grep "search_term_here" | awk "{print $1}" | xargs -r --no-run-if-empty docker stop && \ | |
| docker ps -a --no-trunc | grep "search_term_here" | awk "{print $1}" | xargs -r --no-run-if-empty docker rm && \ | |
| docker images --no-trunc | grep "search_term_here" | awk "{print $3}" | xargs -r --no-run-if-empty docker rmi | |
| # stops only exited containers and delete only non-tagged images | |
| docker ps --filter 'status=Exited' -a | xargs docker stop docker images --filter "dangling=true" -q | xargs docker rmi | |
| ### DELETE NETWORKS AND VOLUMES ### | |
| # clean up orphaned volumes | |
| docker volume rm $(docker volume ls -qf dangling=true) | |
| # clean up orphaned networks | |
| docker network rm $(docker network ls -q) | |
| ### NEW IMAGES/CONTAINERS ### | |
| # create new docker container, ie. ubuntu | |
| docker pull ubuntu:latest # 1x pull down image | |
| docker run -i -t ubuntu /bin/bash # drops you into new container as root | |
| ### OTHER ### | |
