ECS Maintain Tips(1)Clean Docker Images/Applications

Clean ECS to release data storage

I found sometimes ECS shutdown the docker application, but left the exited application data there. Sometimes, ECS upgrade the images, but left the <none> version images there.

Command to check all applications including exited ones.

>docker ps -a

65469eab87f8        xxxxxx.dkr.ecr.us-east-1.amazonaws.com/xxxxx      "./start.sh"        About an hour ago   Exited (255) About an hour ago                                ecs-fr-task-process-42-jobs-producer-xxxxxx

Clean the exited applications

>docker rm $(docker ps -a | grep "Exited (255)" | awk "{print \$1}")

Command to list all images including the none version ones

>docker images

Clean the <none> version images

>docker rmi $(docker images | grep "<none>" | awk "{print \$3}")
