在docker容器中运行Haproxy

我试图从haproxy图像创建Docker容器，但遇到了一些问题。我按照教程的说明创建了一个包含

FROM haproxy:1.7  
COPY haproxy.cfg /usr/local/etc/haproxy/haproxy.cfg

然后我运行

docker build-t my haproxy.

一切看起来都很好，但是当我运行

docker run-it--rm--name haproxy语法时，请检查我的haproxy-haproxy-c-f/usr/local/etc/haproxy/haproxy.cfg来测试配置文件，我得到以下错误`s

[ALERT] 114/152637 (1) : parsing [/usr/local/etc/haproxy/haproxy.cfg:7] : cannot find user id for 'haproxy' (0:Success)

每当我拉动官方的Haproxy容器时，我都看不到Haproxy用户/组。实际上，我为haproxy定制图像的全部原因就是添加它们

RUN addgroup -g 1000 haproxy && \
    adduser -u 1000 -G haproxy -h /app -D haproxy 

将用户和组从haproxy更改为root。它会起作用的

global
    log /dev/log    local0
    log /dev/log    local1 notice
    chroot /var/lib/haproxy
    stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
    stats timeout 30s
    user root
    group root
    daemon

在全局部分添加这两行

      user haproxy
      group haproxy

在“默认值”部分删除或注释此行
