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:

在编写Dockerfile创建supervisor容器时,最后一条启动supervisor的命令不起作用 -> CMD ["supervisord","-c","/etc/supervisord.conf"],但是进到容器内部执行supervisord -c /etc/supervisord.conf可以成功运行。

先贴出来Dockerfile文件代码

FROM python:latest 
WORKDIR /root/
 
RUN mkdir /etc/supervisor
RUN mkdir -p /root/projects/logs/gunicorn/
RUN mkdir -p /root/projects/logs/celery/
RUN mkdir -p /root/projects/Sy_EvaluateJkApi/logs/
RUN echo "deb http://mirrors.aliyun.com/debian/ buster main non-free contrib" > /etc/apt/sources.list
RUN echo "deb-src http://mirrors.aliyun.com/debian/ buster main non-free contrib"  /etc/apt/sources.list
RUN echo "deb http://mirrors.aliyun.com/debian-security buster/updates main"  /etc/apt/sources.list
RUN echo "deb-src http://mirrors.aliyun.com/debian-security buster/updates main"  /etc/apt/sources.list
RUN echo "deb http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib"  /etc/apt/sources.list
RUN echo "deb-src http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib"  /etc/apt/sources.list
RUN echo "deb http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib"  /etc/apt/sources.list
RUN echo "deb-src http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib"  /etc/apt/sources.list
RUN apt-get update -y
RUN apt-get install -y git lrzsz vim
RUN pip install supervisor -i https://mirrors.aliyun.com/pypi/simple/
RUN pip install gunicorn -i https://mirrors.aliyun.com/pypi/simple/
RUN pip install gevent -i https://mirrors.aliyun.com/pypi/simple/
RUN /usr/local/bin/echo_supervisord_conf > /etc/supervisord.conf
RUN echo "[include]"/etc/supervisord.conf
RUN echo "files = /etc/supervisor/*.ini"/etc/supervisord.conf
 
ADD sy.ini /etc/supervisor/sy.ini
ADD Sy_EvaluateJkApi /root/projects/Sy_EvaluateJkApi
RUN pip3 install -r /root/projects/Sy_EvaluateJkApi/requirements.txt -i https://mirrors.aliyun.com/pypi/simple/
EXPOSE 8800
CMD ["supervisord","-c","/etc/supervisord.conf"]

使用docker build -t system:test . 命令构建容器镜像没有异常,但是使用docker run -itd system:test运行容器就会显示容器不在运行。

解决方式:

把CMD ["supervisord","-c","/etc/supervisord.conf"]命令改成CMD ["supervisord","-n","-c","/etc/supervisord.conf"]就可以成功运行了。

supervisor里是这么写的-n/--nodaemon -- run in the foreground (same as 'nodaemon=true' in config file),加了-n让supervisor在前台保持运行就可以了。

以上这篇supervisor下的Dockerfile的多服务镜像封装操作就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
