使用 docker 注册表错误 500 设置 GitHub

Question

我在example.domain.com上运行了带有 docker 注册表的 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

我可以推送和拉取到这个 docker 注册表，但是当我尝试将其与在同一台机器上运行的 gitlab 连接时example.domain.comgitlab.yml配置：

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Web浏览器中，在项目上启用docker注册表工作正常，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 注册表日志：

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，您收到TLS握手错误。

将 gitlab 配置从

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

自

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

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