当我启动容器时最后一个屏幕命令没有运行，但是当我进入容器并运行它运行的完全相同的命令时。 dockerfile 使用 reHLDS 构建 Counter-Strike 1.6 服务器。

编辑：在我运行容器时尝试了 ti7 方法后，它给了我这个错误：

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"start.sh\": executable file not found in $PATH": unknown.

这是我尝试过的代码：

echo "#!/bin/sh" >> /home/cs/start.sh &&\
    echo "# start.sh" &&\
    echo "screen -A -m -d -S cs /home/cs/hlds_run -game cstrike +maxplayers 25 +map de_dust2 -autoupdate -pingboost 3" >> /home/cs/start.sh &&\
    chmod +x /home/cs/start.sh &&\
    /home/cs/start.sh
WORKDIR /home/cs/
ENTRYPOINT ["/home/cs/start.sh"]

这是我运行图像的命令：

sudo docker run -itd -p 27015:27015/udp --name=cs cstrike /bin/bash

【问题讨论】：

标签： linux docker dockerfile

【解决方案1】：

屏幕是在容器完成之前创建的

在ENTRYPOINT或它调用的脚本中直接设置容器开始时应该以容器开头的命令

#!/bin/bash
# start.sh
screen screen_command

# exec the final command replacing this script with the new process
# this makes the new process the forefront in Docker, keeping the container
# running until it exits and allowing signals to be passed (such as ^C)
exec sleep infinity

...
RUN generate_script.sh
WORKDIR /home/cs/
ENTRYPOINT ["/home/cs/start.sh"]

使用ENTRYPOINT，运行容器时无需指定任何shell
名称后传递的参数将被发送到容器中，并且可以被脚本more进行解释

docker run --detach --init --name foo-name container

【讨论】：

CMD 可能更好。
我的经历参差不齐，我记得ENTRYPOINT 更方便将参数传递给（尽管可能不是或可能不再是这种情况）
@Zeth 啊，你应该用完整或相对路径来调用它 - 我也更新了我的答案
有效吗？图层应该被缓存
@ti7 现在容器在 1 秒后存在
