通过主管关闭Docker容器

显然,CMD myexec param1 param2启动了一个外壳,它反过来启动了myexec(实际上这两个进程在容器中可见,在PID 1中有/ bin / sh -c myexec ….更好的方法是直接启动程序我的情况supervisord).

另一方面,CMD [“/usr/bin/python”,“/usr/local / bin / supervisord”,“-c”,“/root/supervisord.conf”,“–nodaemon”我现在能够通过主管启动和停止码头集装箱.

停泊处的相关部分Here’s docs：

The CMD instruction has three forms:

CMD ["executable","param1","param2"] (exec form,this is the preferred form)

CMD ["param1","param2"] (as default parameters to ENTRYPOINT)

CMD command param1 param2 (shell form)

更新

示例管理员文件(Docker容器内)：

[program:app]
command=python run_web_server.py
stdout_logfile=/var/log/app/app.log
directory=/opt/app
autostart=true
autorestart=false
stopsignal=INT
redirect_stderr=true
startretries=0
stopasgroup=true
killasgroup=true


[unix_http_server]
file=/var/run/supervisor.sock
chmod=0700

[supervisord]
logfile=/var/log/supervisor/supervisord.log
pidfile=/var/run/supervisord.pid
childlogdir=/var/log/supervisor

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock
