1.问题描述
docker在删除两个相同IMAGE ID镜像(E.g:docker rmi 605c77e624dd)时，会有如下报错：
Error response from daemon: conflict: unable to delete 605c77e624dd (must be forced) - image is referenced in multiple repositories
[root@centos79 ~]# docker images | grep nginx
nginx-test 1.0 605c77e624dd 23 months ago 141MB
nginx latest 605c77e624dd 23 months ago 141MB
[root@centos79 ~]# docker rmi 605c77e624dd
Error response from daemon: conflict: unable to delete 605c77e624dd (must be forced) - image is referenced in multiple repositories
[root@centos79 ~]#2.解决方案
2.1.方案一：
使用repository加tag的方式进行image的删除。
命令：
docker rmi nginx-test:1.0
[root@centos79 ~]# docker images | grep nginx
nginx-test 1.0 605c77e624dd 23 months ago 141MB
nginx latest 605c77e624dd 23 months ago 141MB
[root@centos79 ~]# docker rmi nginx-test:1.0
Untagged: nginx-test:1.0
[root@centos79 ~]# docker images | grep nginx
nginx latest 605c77e624dd 23 months ago 141MB
[root@centos79 ~]#2.2.方案二：
使用docker rmi -f 的方式进行镜像的删除，不过该方式会把两个相同IMAGE ID镜像全部删除。
命令：
docker rmi -f IMAGE_ID
-f：--force Force removal of the image
[root@centos79 ~]# docker images | grep nginx
nginx-test 1.0 605c77e624dd 23 months ago 141MB
nginx latest 605c77e624dd 23 months ago 141MB
[root@centos79 ~]# docker rmi -f 605c77e624dd
Untagged: nginx-test:1.0
Untagged: nginx:latest
