Question

我正在尝试使用here和here

步骤设置docker注册表镜像

我用来启动注册表镜像的命令是

docker run -d --restart=always -p 5000:5000 --name registry-mirror -v /Users/proxycache/docker-proxy-cache/data:/var/lib/registry -v /Users/proxycache/docker-proxy-cache/config:/etc/docker/registry registry:2

我的配置看起来像

version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
  delete:
    enabled: true
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3
proxy:
  remoteurl: https://registry-1.docker.io

我没有设置任何证书，因为这只是本地的，并没有绑定到域。

启动后我可以运行curl -I http://proxycache.local:5000/v2/而我

HTTP/1.1 200 OK
Content-Length: 2
Content-Type: application/json; charset=utf-8
Docker-Distribution-Api-Version: registry/2.0
X-Content-Type-Options: nosniff
Date: Mon, 20 Feb 2017 17:52:21 GMT

我也可以curl http://proxycache.local:5000/v2/_catalog运行

{"repositories":[]}

然后我使用此命令minikube start --vm-driver=xhyve --disk-size=40g --memory=8192 --registry-mirror http://proxycache.local:5000 --insecure-registry http://proxycache.local:5000

启动minikube

eval $(minikube docker-env)

如果我运行docker info，我会

它所说的部分

Registry Mirrors:
 http://proxycache.local:5000/

似乎表明minikube设置正确

如果我运行docker pull busybox:latest，它会下载图像，但不会更新镜像。如果我拉出目录curl http://proxycache.local:5000/v2/_catalog，它仍然是空的

我还缺少什么？

根据请求，这是我从docker logs registry-mirror

获得的

Answer 1

所以似乎docker或者coreos不喜欢我们设置DNS的方式。我最终不得不使用镜像的IP地址而不是DNS名称，现在它可以工作。

Docker注册表镜像不使用minikube保存图像
