1. 全部清理

该清理包括：容器、网络、镜像、cache

[root@das-meeting-16 ~]# docker system prune
WARNING! This will remove:
        - all stopped containers
        - all networks not used by at least one container
        - all dangling images
        - all build cache
Are you sure you want to continue? [y/N] y
Deleted Networks:
app_kong-net
boe-iotgw-server_default
 
Deleted Images:

如上可知：

    - all stopped containers
    - all networks not used by at least one container
    - all dangling images
    - all build cache

当然也可以对以上项目分别进行清理

2. 容器清理

• 删除所有已停止的容器

# docker container prune
WARNING! This will remove all stopped containers.
Are you sure you want to continue? [y/N] y

• 删除停止指定时间的容器
  如：删除停止24h以上的容器

# docker container prune --filter "until=24h" 

3. 镜像清理

• 清理dangling 状态的容器

# docker image prune
WARNING! This will remove all dangling images.
Are you sure you want to continue? [y/N] y

说明：dangling 状态为容器名和tag都为空的镜像，如：

<none>         <none>           2122db2ff445        3 weeks ago         49.7MB

• 清理所有未使用的镜像

# docker image prune -a
 
WARNING! This will remove all images without at least one container associated to them.
Are you sure you want to continue? [y/N] y

• 删除指定时间外未被使用过的镜像
  如：删除停止24h以上未被使用过angling 状态的镜像

# docker image prune --filter "until=24h" 

4. 存储卷清理

• 删除未被使用的卷

# docker volume prune
WARNING! This will remove all volumes not used by at least one container.
Are you sure you want to continue? [y/N] y

• 清理挂载卷labe不是keep的卷

没看懂！！！这个是从docker volume inspect xxx 命令看到的结果都是null

 docker volume prune --filter "label!=keep"

5. 网络清理

• 删除未被使用的网络

#  docker network prune
WARNING! This will remove all networks not used by at least one container.
Are you sure you want to continue? [y/N] y

• 删除24小时未被使用的网络

# docker network prune --filter "until=24h"

6. 日志清理
