Error response from daemon: conflict: unable to delete 4ac2d12f10cd (must be forced) - image is referenced in multiple repositories

來自守護程序的錯誤響應：衝突：無法刪除4ac2d12f10cd（必須強制） - 映像在多個儲存庫中被引用

1.刪除映象

檢視映象

root@souyunku:~/mydocker# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               v1                  4ac2d12f10cd        41 minutes ago      108MB
souyunku/nginx      v1                  4ac2d12f10cd        41 minutes ago      108MB
hello-world         latest              f2a91732366c        5 weeks ago         1.85kB
 

刪除失敗

刪除其中一個映象，這裡的映象有1個repo引用，並且沒有容器使用

並且沒有容器使用

root@souyunku:~/mydocker# docker container ls -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                         PORTS               NAMES
4c104074b3f4        hello-world         "/hello"            About an hour ago   Exited (0) About an hour ago                       priceless_hawking
 

映象有1個repo引用

root@souyunku:~/mydocker# docker rmi 4ac
Error response from daemon: conflict: unable to delete 4ac2d12f10cd (must be forced) - image is referenced in multiple repositories

2.解決方法

刪除REPOSITORY

被刪除的ImageID，這裡存在1個REPOSITORY名字引用，解決方法如下：

即刪除時指定名稱，而不是IMAGE ID。

root@souyunku:~/mydocker# docker rmi souyunku/nginx:v1
Untagged: souyunku/nginx:v1
 

再刪除IMAGE ID就可以了：

root@souyunku:~/mydocker# docker rmi 4ac
Untagged: nginx:v1

3.檢視映象

root@souyunku:~/mydocker# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
