Docker-Compose 无法复制 haproxy.cfg

Question

我的问题是，我有一个 docker-compose.yml 文件和一个 haproxy.cfg 文件，我希望 docker-compose 复制 haproxy。 cfg 文件到 docker 容器。根据帖子Docker composer copy files我可以使用卷来做到这一点，但就我而言，我收到以下错误。谁能帮我实现这个目标。

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

Answer 1

试试这个:

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

这只会挂载 haproxy.cfg，而不是挂载整个目录。 ro 是只读的缩写，它的使用保证容器在挂载后不会对其进行修改。
