supervisor下的Dockerfile的多服务镜像封装 *** 作

本文主要介绍了在supervisor下Dockerfile的多业务图像封装 *** 作，具有很好的参考价值。希望对你有帮助。来和边肖一起看看吧。

写入Dockerfile文件

卷曲度

认证sshd服务:

补充知识:使用Dockerfile构建supervisor容器部署项目，cmd["supervisord"、"-c"、"/etc/supervisord.conf"]执行失败

问题描述:

编写Dockerfile创建supervisor容器时，最后一个启动supervisor的命令不起作用-->:Cmd["supervisord"，"-c"，"/etc/supervisord.conf"]，但是在容器内部执行supervisord-c/etc/supervisord.conf可以成功运行。

首先发布Dockerfile文件代码

FROMpython:latest WORKDIR/root/ RUNmkdir/etc/supervisor RUNmkdir-p/root/projects/logs/gunicorn/ RUNmkdir-p/root/projects/logs/celery/ RUNmkdir-p/root/projects/Sy_EvaluateJkApi/logs/ RUNecho"debhttp://mirrors.aliyun.com/debian/bustermainnon-freecontrib">/etc/apt/sources.list RUNecho"deb-srchttp://mirrors.aliyun.com/debian/bustermainnon-freecontrib">>/etc/apt/sources.list RUNecho"debhttp://mirrors.aliyun.com/debian-securitybuster/updatesmain">>/etc/apt/sources.list RUNecho"deb-srchttp://mirrors.aliyun.com/debian-securitybuster/updatesmain">>/etc/apt/sources.list RUNecho"debhttp://mirrors.aliyun.com/debian/buster-updatesmainnon-freecontrib">>/etc/apt/sources.list RUNecho"deb-srchttp://mirrors.aliyun.com/debian/buster-updatesmainnon-freecontrib">>/etc/apt/sources.list RUNecho"debhttp://mirrors.aliyun.com/debian/buster-backportsmainnon-freecontrib">>/etc/apt/sources.list RUNecho"deb-srchttp://mirrors.aliyun.com/debian/buster-backportsmainnon-freecontrib">>/etc/apt/sources.list RUNapt-getupdate-y RUNapt-getinstall-ygitlrzszvim RUNpipinstallsupervisor-ihttps://mirrors.aliyun.com/pypi/simple/ RUNpipinstallgunicorn-ihttps://mirrors.aliyun.com/pypi/simple/ RUNpipinstallgevent-ihttps://mirrors.aliyun.com/pypi/simple/ RUN/usr/local/bin/echo_supervisord_conf>/etc/supervisord.conf RUNecho"[include]">>/etc/supervisord.conf RUNecho"files=/etc/supervisor/*.ini">>/etc/supervisord.conf ADDsy.ini/etc/supervisor/sy.ini ADDSy_EvaluateJkApi/root/projects/Sy_EvaluateJkApi RUNpip3install-r/root/projects/Sy_EvaluateJkApi/requirements.txt-ihttps://mirrors.aliyun.com/pypi/simple/ EXPOSE8800 CMD["supervisord","-c","/etc/supervisord.conf"]

使用dockerbuild-tsystem:test时没有异常。命令构建容器映像，但是用dockerbuild-itdsystem:test运行容器将显示容器没有运行。

解决方案:

将cmd["supervisord"、"-c"、"/etc/supervisord.conf"]命令更改为cmd["supervisord"、"-n"、"-c"、"/etc/supervisord.conf"]，它将成功运行。

它被写在supervisor-n/-nodaemon-run中的前台(与配置文件中的'nodaemon=true'相同)，添加-n是为了保持supervisor在前台运行。
