推荐答案

，您还可以 docker exec -it container_id bash ，然后 kill -9 主进程.我用 docker run -d --restart = always -e DISPLAY = $ DISPLAY -v/home/gg/moncontainer:/home/gg -v/tmp/.X11-unix:/tmp/.X11-测试了Unix k3ck3c/captvty 我杀死了主进程(pid 5，Captvty.exe)，从容器中注销，并在2秒后重新启动，再次创建了窗口

you can also docker exec -it container_id bash and then kill -9 of the main process. I tested with docker run -d --restart=always -e DISPLAY=$DISPLAY -v /home/gg/moncontainer:/home/gg -v /tmp/.X11-unix:/tmp/.X11-unix k3ck3c/captvty I killed the main process (pid 5, Captvty.exe), was logged out of the container, and 2 seconds later it was restarted, the window was created again
