艰巨的任务:每次我尝试停止或杀死正在运行的容器时,我都会被拒绝权限作为守护程序的错误响应。
我刚刚开始使用 Ubuntu18.04 VM 来使用 docker。我是第一次运行容器。我无法阻止它,但至少它在运行。现在,在我尝试运行另一个图像"furtuas/daisitory:image_available_first_ms"之后,一切都变得更糟了。两个容器正在运行,我无法阻止它们中的任何一个。我尝试重新启动 docker,但容器仍在运行,不同之处在于本地主机不再工作。也许它发生在我像以前的主机一样在同一个主机上运行
我不熟悉Docker,ubuntu,终端等。我将不胜感激初学者的详细答案

请帮忙。

注销 VM 后,仍然相同的响应:
$ docker stop 66c6c49a95f4
Error response from daemon: cannot stop container: 66c6c49a95f4: Cannot kill container 66c6c49a95f499abeb62b1c02e7e9b8ce1739709bb2140ba7b1a61094a9d16f7: unknown error after kill: runc did not terminate sucessfully: container_linux.go:387: signaling init process caused "permission denied"

这个答案帮助我解决了这个问题
执行 sudo aa-remove-unknown
成功执行后,docker stop
命令将起作用。
我解决了它,但我不知道为什么。我想我通过重新启动 VM 并使用这些命令重新启动 docker 解决了它
齐平变化:$ sudo systemctl daemon-reload
重新启动 Docker: $ sudo systemctl restart docker
使用技巧:
sudo killall docker-containerd-shim
将docker
从像这样卡住的停止容器中释放出来
你试过docker stop <container-id>
还是docker kill <container-id>
?
注意:使用docker ps -a
获取容器 ID
另外,您使用的是sudo
还是记录为root
?
这可能是由Ubuntu的安全性引起的,特别是apparmor
。在这种情况下,您应该已将 docker 运行--security-opt apparmor:unconfined
添加到 docker 中。这似乎比移除盔甲更可取。
例如,尝试:
docker run --security-opt apparmor:unconfined -ti ubuntu bash
然后尝试docker stop
,看看它有效!
处所述,检查入口点脚本是否以以下内容开头:
#!/bin/bash -xe
系统将阻止容器停止。为了解决此问题,请更改不带"e"的入口点脚本
#!/bin/bash -x
我无法停止容器,所以我只是重新启动了容器服务,它工作了 ->sudo systemctl restart containerd
这些命令都不起作用,只是重新启动主机工作,但这意味着所有正在运行的容器都停止了,如果有人可以提供帮助,我需要解决方案。注意:--security-opt apparmor:unconfined
使主机无法工作,docker 命令停止工作,我不得不重建其他容器
我遇到了同样的问题。与装甲服务有一些冲突。在 Ubuntu 上,我可以通过重新安装 apparmor 来解决此问题:
- sudo apt-get purge apparmor
- sudo apt-get install apparmor
- sudo /etc/init.d/apparmor start
