报错

删除镜像时报错：

[root@iZhp33j6fklnmhbf0lz2obZ ~]# docker rmi test:latest 
Error response from daemon: conflict: unable to remove repository reference "test:latest" (must force) - container 
1c21d7ca4d79 is using its  referenced image 90cb9f03bf34

解决

报错内容是因为镜像被容器引用，那么删除容器在删除镜像。

# 删除容器
docker rm 1c21d7ca4d79

[root@iZhp33j6fklnmhbf0lz2obZ ~]# docker rm 1c21d7ca4d79
Error response from daemon: You cannot remove a running container 1c21d7ca4d79eddd1e81112af422f1e878882174b625f707ecd5e04a08f6aed5. 
Stop the container before attempting removal or force remove

报错：Error response from daemon: You cannot remove a running container
