docker-组成卷不能以这种方式工作

Question

在我的docker-compose.yml中，我使用注册表:2镜像(版本)，因为我需要设置我自己的配置(为了使用S3存储)，我尝试将我的配置目录堆在默认目录的位置

/usr/share/docker- registry / config /config.yml #我自己在本地主机/go/src/github.com/docker/distribution/cmd/registry/config.yml中的注册表配置#容器中的默认配置

在我的docker-compose.yml中，我写道

backend: 
  image: registry:2
  ports:
    - 127.0.0.1:5000:5000 
  links: 
    - cache 
  volumes:
    - /usr/share/docker-registry/config:/go/src/github.com/docker/distribution/cmd/registry
 ..

但当我编写它时，我的配置设置永远不会被考虑在内……它始终使用容器cmd/registry/config.yml中的默认设置

会出什么问题呢？

如果我检查正在运行的registry:v2容器，可以看到

感谢您的启迪...

如果我检查正在运行的registry:v2容器，就会发现配置很奇怪(有S3信息，但没有卷，而且CMD正在执行标准的config.yml文件... )

我需要用环境变量覆盖设置。不使用外部卷..
