Problem
Using Docker for Mac long time uses large storage spaces.
sot-mbp:clean_docker_resources sot528$ docker system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 152 2 37.57GB 35.79GB (95%)
Containers 4 0 35.8MB 35.8MB (100%)
Local Volumes 4 0 7.118MB 7.118MB (100%)
Build Cache 0 0 0B 0B
Solution
docker system prune
Then, SIZE is be around 30GB.
And remove old images without recent 10 images.
docker rmi -f $(docker images | sed -n '10,$p')
Result
Good!
