Docker-Compose无法复制haproxy.cfg [英] Docker-Compose not able to copy haproxy.cfg

问题描述

我的问题是我有一个docker-compose.yml文件和一个haproxy.cfg文件，我想让docker-compose将haproxy.cfg文件复制到docker容器中.根据 Docker composer复制文件的帖子，我可以使用卷来做，但是就我而言正在收到以下错误.谁能帮我实现这一目标.

My problem is that I have a docker-compose.yml file and an haproxy.cfg file and I want docker-compose to copy the haproxy.cfg file to the docker container. As per the post Docker composer copy files I can use volumes to do it but in my case I'm getting the below error. Can anybody help me achieve this.

下面是代码和所有内容

docker-compose.yml

version: "3.3"
services:
 ###After all services are up, we are initializing the gateway
 gateway:
  container_name: gateway-haproxy
  image: haproxy
  volumes:
    - .:/usr/local/etc/haproxy
  ports:
   - 80:80
  network_mode: "host"

文件夹结构

命令输出

root@ubuntu:/home/karunesh/Desktop/Stuff/SelfStudy/DevOps/docker# docker-compose up

推荐答案

尝试一下:

volumes:
  - ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro

仅装载haproxy.cfg，而不是装载整个目录. ro是只读的缩写，它的用法可确保容器在挂载后不会对其进行修改.

Instead of mounting the whole directory, this will only mount haproxy.cfg. The ro is an abbreviation for read-only, and its usage guarantees the container won't modify it after it gets mounted.
