杀死容器时,在ubuntu 16.04错误的docker

Question

我不能杀死或停止任何码头集装箱.我允许非特权用户运行Docker命令.并且docker run hello-world工作正常.但我不能阻止任何其他容器.

我得到了以下:

$ docker stop 59e3b815d1dc
Error response from daemon: cannot stop container: 59e3b815d1dc: 
Cannot kill container 59e3b815d1dcf2d8c8bcd3dd641c3c033b83ac68ea2f0257a32a76468af7374c: 
unknown error after kill: docker-runc did not terminate sucessfully: 
container_linux.go:393: signaling init process caused "permission denied"
: unknown

与sudo相同的错误.同时,所有容器都成功运行,但要停止它们只能完全重启系统.

Docker撰写示例:#使用postgres/example用户/密码凭证版本:'3.1'

services:

  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_PASSWORD: example

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

Answer 1

对我来说，从AppArmor作品中删除未知的作品：

sudo aa-remove-unknown

Answer 2

AppArmor(Application Armor)是一个Linux安全模块,可以保护操作系统及其应用程序免受安全威胁.要使用它,系统管理员会将AppArmor安全配置文件与每个程序相关联.Docker希望找到一个加载并强制执行的AppArmor策略.检查默认配置文件:

# sudo apparmor_status

要在容器上使用docker默认配置文件,请运行:

$ docker run --rm -it --name test-container --security-opt apparmor=docker-default image-name

您可以使用以下命令禁用它:

--security-opt apparmor=unconfined

使用docker run命令.

要禁用apparmor服务,请使用:

# systemctl stop apparmor && systemctl disable apparmor

对于Ubuntu 14.使用:

# service apparmor stop
# update-rc.d -f apparmor remove

建议为Docker apparmor设置工作配置文件而不是禁用它,尤其是对于生产设置.

查看关于使用AppArmor保护容器的这个非常棒的Google文档.

Answer 3

此命令将停止所有docker容器.

sudo killall docker-containerd-shim

此命令将删除所有docker容器.

sudo docker-compose down

Answer 4

只需在终端中运行此命令，所有正在运行的 docker 容器都将停止

sudo systemctl restart docker.service
