一、磁盘清理

# docker system  --help

# docker system df  --help

# docker system prune    --help

二、删除非Up容器

# docker ps --help

# docker rm --help

# docker ps -a | grep "Exited" | awk '{print $1}' | xargs docker rm

# docker ps -a | grep "Dead" | awk '{print $1}' | xargs docker rm

# docker ps -a | grep "Created" | awk '{print $1}' | xargs docker rm

# docker ps -a | grep -E "Exited|Dead|Created" | awk '{print $1}' | xargs docker rm
