我在尝试清除Docker创建的图像时遇到了一个奇怪的问题.这就是我做的：
>删除所有容器
$docker rm $(docker ps -a -q)
bb3927e956bf
3e2eeb6287c4
>检查是否有任何容器在运行或创建后：
$docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
>删除所有图像：第一次尝试失败,因为图像被引用
$docker rmi $(docker images -q)
Error response from daemon: conflict: unable to delete 2f21ea981017 (must be forced) - image is referenced in one or more repositories
Error response from daemon: conflict: unable to delete 2f21ea981017 (must be forced) - image is referenced in one or more repositories
>使用-f选项删除所有图像：
$docker rmi -f $(docker images -q)

Error response from daemon: No such image: 2f21ea981017:latest
Error response from daemon: reference does not exist
然后这个错误：没有这样的形象：2f21ea981017：最新出现,我应该问,为什么？这样的形象在哪里？ Docker有哪种内部数据库存储信息？
运行所有以前的命令后,我运行以下命令并注意输出：
$docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu 14.04.5 b1719e1db756 3 days ago 187.9 MB
但后来我尝试通过运行再次删除图像
$docker rmi b1719e1db756
Error response from daemon: reference does not exist
我得到了同样的错误,我在这里错过了什么？我怎么解决这个问题？
我应该补充说,我还运行了this post的命令,但没有成功.
最佳答案
@H_404_59@我在docker-ce 17.06 / fedora 26上遇到过这个问题.我认为您不需要删除docker,但这些命令会删除所有图像.因此请保存您真正需要的任何图像,删除所有图像并恢复备份;
sudo systemctl stop docker.service
sudo rm -rf /var/lib/docker
sudo systemctl start docker.service
