docker使用问题整理

镜像处理相关

1.无法删除所有镜像，提示如下

[@localhost:~]$ docker rmi $(docker images -q)
Error response from daemon: conflict: unable to delete af2f74c517aa (must be forced) - image is referenced in multiple repositories
Error response from daemon: conflict: unable to delete af2f74c517aa (must be forced) - image is referenced in multiple repositories

出现上面问题的原因：
对于被删除的ImageID，这里存在多个REPOSITORY名字引用，解决方法如下：

[@localhost:~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox latest af2f74c517aa 5 weeks ago 1.2MB
test-docker-hub.dding.net/admin/busybox latest af2f74c517aa 5 weeks ago 1.2MB
test-docker-hub.dding.net/admin/wuxiaoyu latest af2f74c517aa 5 weeks ago 1.2MB
test-docker-hub.dding.net/busybox latest af2f74c517aa 5 weeks ago 1.2MB
[@localhost:~]$ docker rmi test-docker-hub.dding.net/busybox:latest
Untagged: test-docker-hub.dding.net/busybox:latest
[@localhost:~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox latest af2f74c517aa 5 weeks ago 1.2MB
test-docker-hub.dding.net/admin/busybox latest af2f74c517aa 5 weeks ago 1.2MB
test-docker-hub.dding.net/admin/wuxiaoyu latest af2f74c517aa 5 weeks ago 1.2MB
[@localhost:~]$

即删除时指定名称，而不是IMAGE ID

2.无法删除被stop container引用的image，提示如下

[@localhost:~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox latest af2f74c517aa 5 weeks ago 1.2MB
[@localhost:~]$ docker rmi af2f74c517aa
Error response from daemon: conflict: unable to delete af2f74c517aa (must be forced) - image is being used by stopped container ce1cd38f5311
[@localhost:~]$

解决方法:

[@localhost:~]$ docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                        PORTS               NAMES

[@localhost:~]$ docker rm ce1cd38f5311  #删除容器
ce1cd38f5311
[@localhost:~]$ docker rmi busybox  #删除镜像

即先删除容器，然后删除镜像。
