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:
[root@kazihuo ~]# 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
[root@kazihuo ~]# 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;
[root@kazihuo ~]# docker rmi nginx-file:v1
Untagged: nginx-file:v1
[root@kazihuo ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE kazihuo/nginx v1 60c22883bb42 11 minutes ago 372 MB
