docker - 设置gitlab与Docker注册表错误500

Question

我在example.domain.com上使用docker Registry运行docker

docker run -d -p 5000:5000 --restart=always --name registry \
-v /etc/ssl/certs/:/certs \
-e REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/var/lib/registry \
-v /git/docker_registry:/var/lib/registry \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/server.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/server.key \
registry:2

我可以推送并拉到该docker注册表，但是当我尝试使用 example.domain.com配置将它与运行在同一台机器 gitlab.yml上的gitlab连接时:

  registry:
    enabled: true
    host: example.domain.com
    port: 5005
    api_url: http://localhost:5000/
    key: /etc/ssl/certs/server.key
    path: /git/docker_registry

在网络浏览器中，在项目上启用Docker注册表可以正常工作，但是当我转到项目页面并打开 Regisry page时，出现错误500

Gitlab日志显示:

和Docker Registry日志:

2016/11/25 09:15:01 http: TLS handshake error from 172.17.0.1:44608: tls: first record does not look like a TLS handshake

Answer 1

问题是gitlab尝试通过http而不是httpS连接到注册表。因此，您将收到TLS握手错误。

从更改您的gitlab配置

registry:
  api_url: http://localhost:5000/

至

registry:
  api_url: https://localhost:5000/

如果您使用的是自签名证书，请不要忘记在安装gitlab的计算机上信任它。参见-> https://docs.docker.com/registry/insecure/#troubleshooting-insecure-registry
