为什么我不能在ubuntu上移除正在运行的docker容器?

Question

我试图清除我当前的docker容器，但我得到了权限拒绝错误:

我想我没有以root身份运行它们，但即使以root身份运行，我也会得到相同的错误。

如何修复?

谢谢!

Answer 1

您必须在删除它们之前杀死/停止所有正在运行的容器。可以通过运行

下面的cmd命令来终止/停止它。

docker kill $(docker ps -q)
or
docker stop $(docker ps -aq)

，然后通过

删除

docker rm $(docker ps -a -q)

Answer 2

可能与AppArmor有关。检查您是否从不同的来源安装了多个docker实例，因为这可能导致冲突的AppArmor配置文件。

我可以看到你使用的是Ubuntu——所以你有可能通过snap提供了额外的docker。
