Just what I was looking for . Thank You
This is great, Thank you! May I add this one as well:
# Removes all unused volumes that contain numeric values (i.e: bbd0c58ae90b5a63615388543180cc703d6aaf96d268068833e4ecb4ac1e3d5d).
# It will not remove the volumes that are currently in use
docker volume rm $(docker volume ls | grep "[0-9]")
I have list of containers with different container name and now I want to first grep all the containers with similar container name and stop all containers running since last 3 days. Can anyone please help me with command?
I tried:
docker ps -a | grep -i "ngnix" | xargs docker container prune --force --filter "until=3days"
nginx - say keyword in the name of containers
The awk filters on lines 36, 37 & 39 did not work on my Ubuntu 20.04 host, (bash and zsh tested,) as they use double quotes. Swapping them for single quotes worked for me:
# 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
What is the usecase for:
docker exec -it $(docker container ls | grep '<seach_term>' | awk '{print $1}') shCompared to:
docker exec -it <container_name> sh?
Thank you for this this would be very helpful!
