Docker删除镜像报错

Posted 2020-11-20 kazihuo

问题描述：

笔者意图删除nginx-file的镜像文件，但通过命令删除镜像时出现报错信息，提示存在多个引用（即一个IMAGE可被多个REPOSITORY引用，故删除会出现失败），如下：

[[email protected] ~]# docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
kazihuo/nginx       v1                60c22883bb42        6 minutes ago       372 MB
nginx-file          v1                60c22883bb42        6 minutes ago       372 MB

[[email protected] ~]# docker rmi 60c22883bb42

Error response from daemon: conflict: unable to delete 60c22883bb42 (must be forced) - image is referenced in multiple repositories

 

解决方案：

当指定IMAGE ID删除报错时，可直接通过REPOSITORY:TAG的方式删除；

[[email protected] ~]# docker rmi nginx-file:v1

Untagged: nginx-file:v1

[[email protected] ~]# docker images

REPOSITORY       TAG                 IMAGE ID            CREATED             SIZE
