运行2个程序的Docker Alpine Linux [英] Docker Alpine linux running 2 programs

问题描述

我正在尝试使用alpine linux创建docker映像，运行后将创建带有2个正在运行的程序的容器。这2个（我认为-我不太了解docker）无法分开，因为第一个程序更改了秒配置文件，然后也应该重新启动该程序。

I am trying to create docker image with alpine linux, which after run will create container with 2 running programs. This 2 (in my opinion - I don't know docker well) can't be separated because first program changes the seconds configuration file and then should restart that program too.

我正在努力运行两个程序。我添加了自己的脚本，该脚本应该运行该程序，但我缺少一些东西-脚本是每行2行是用于运行该程序的命令-而且它仅启动第一个程序。

I am struggling how to run both programs. I have added own script which should run that programs but I am missing something - script is 2 lines on each line is command for running that program - and it only starts first program.

在带有python子进程和systemctl命令的ubuntu中，我重新启动运行的服务，但在高山linux中，它作为程序运行，我不知道如何重新启动/重新加载它。

In ubuntu with python subprocess and systemctl command I restart running service but in alpine linux it's running as program and I don't know how to restart/reload it.

推荐答案

我建议您看一下 supervisord 方法。您可以在 docker文档中找到使用方法。

I would suggest to look at supervisord approach. You can find how to use it in docker documentation.

例如：

1。 Dockerfile 是：

FROM alpine:latest
RUN apk update && apk add --no-cache supervisor openssh nginx
COPY supervisord.conf /etc/supervisord.conf
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisord.conf"]

2。 supervisord.conf 是：

[supervisord]
nodaemon=true

[program:sshd]
command=/usr/sbin/sshd -D

[program:nginx]
command=nginx -c /etc/nginx/nginx.conf
