docker删除镜像image is referenced in one or more repositories

来源：网络文章列表 2020-04-11 8

我们在删除镜像的时候，有时候会报：image is referenced in one or more repositories的错误，出现此错误的原因是：被删除的ImageID，这里存在多个REPOSITORY名字引用

1. 首先查看镜像

docker images

REPOSITORY                             TAG                 IMAGE ID                  CREATED               SIZE
jenkins                                2.19.4              ff6f0851ef57             2 weeks ago           714.1 MB
jenkins/jenkins                        2.19.4              ff6f0851ef57             2 weeks ago           714.1 MB
192.168.1.110/centos/centos            7.2                 38ea04e19303            12 months ago          194.6 MB
192.168.1.111/centos/centos            7.2                 38ea04e19303            12 months ago          194.6 MB

2. 删除其中一个镜像，这里的镜像有两个repo引用，并且没有容器使用

docker rmi 38ea04e19303

# 错误提示：
Error response from daemon: conflict: unable to delete 38ea04e19303 (must be forced) - image is referenced in one or more repositories

出现上面问题的原因：
对于被删除的ImageID，这里存在多个REPOSITORY名字引用，解决方法如下：

docker rmi 192.168.1.111/centos/centos:7.2

Untagged: 192.168.1.111/centos/centos:7.2
Untagged: 192.168.1.111/centos/centos@sha256:05c5e4ffbd3e4e54a685915394858e1dacc38873f02920b57b66551a1626dbd3

即删除时指定名称，而不是IMAGE ID。

然后再删除IMAGE ID就可以了：

docker rmi 38ea04e19303

Untagged: 192.168.1.110/centos/centos:7.2
Untagged: 192.168.1.110/centos/centos@sha256:05c5e4ffbd3e4e54a685915394858e1dacc38873f02920b57b66551a1626dbd3

3. 继续查看剩余的镜像

docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
jenkins/jenkins     2.19.4              ff6f0851ef57        2 weeks ago         714.1 MB
jenkins             2.19.4              ff6f0851ef57        2 weeks ago         714.1 MB
