以下是我在docker-compose.yml文件中创建注册表的方法：

version: "3"
services:
  registry:
    restart: always
    image: registry:latest
    container_name: registry
    ports:
      - 5000:5000
    volumes:
      - ~/dev/docker/registries/registry:/var/lib/registry

我的码头版本是：

$ docker version
Client:
 Version:   17.12.0-ce
 API version:   1.35
 Go version:    go1.9.2
 Git commit:    c97c6d6

Server:
 Engine:

Answer 1

您可以尝试使用-o选项从服务器恢复响应的实际内容，例如：

curl –k –o body.txt -X GET domain.com:5000/v2/_catalog/

然后，更改文件.txt的扩展名，以对应服务器提供的预期内容类型格式。

curl -i -X GET domain.com:5000/v2/_catalog/

检查：

Content-Type: image/png, application/json , etc

服务器发送的数据可能是格式错误的

Answer 2

由于ssl东西，我也遇到了相同的错误，因为我的本地docker注册表受到保护，因此您必须在本地注册表url的开头提到 https：// ...

curl --key <ssl key file> --cacert <ssl pem file> -X GET https://<your local registry url >:<your port>/v2/_catalog

或不安全：

curl -k -X GET https://<your local registry url >:<your port>/v2/_catalog

我的私有存储库在curl GET请求中返回二进制内容
