自建方法

镜像 dockerhub

version: '3.1'
services:
  registry:
    image: registry:2.8.2
    #network_mode: "host"
    environment:
      REGISTRY_HTTP_ADDR: "0.0.0.0:5000"
      REGISTRY_PROXY_REMOTEURL: "https://registry-1.docker.io"
      REGISTRY_PROXY_TTL: 168h 
      HTTPS_PROXY: "http://192.168.25.18:7890"
    restart: always
    container_name: registry
    ports:
      - 5000:5000
    volumes:
      - "./registry:/var/lib/registry"

docker-compose -f registry.yml up -d

镜像 quay

类似的原理可以镜像 quay.io 等等：

version: '3.1'
services:
  mirror-quay-io:  
   image: registry:2.8.2  
   environment:  
     REGISTRY_HTTP_ADDR: "0.0.0.0:5000"  
     REGISTRY_PROXY_REMOTEURL: "https://quay.io"  
     REGISTRY_COMPATIBILITY_SCHEMA1_ENABLED: "true"  
     REGISTRY_PROXY_TTL: 168h  
     HTTPS_PROXY: "http://192.168.25.18:8890"  
   restart: always  
   ports:  
     - 5003:5000  
   volumes:  
     - "./data/quay.io:/var/lib/registry"

参数说明：

• REGISTRY_COMPATIBILITY_SCHEMA1_ENABLED：开启 schema1 支持，默认关闭
• REGISTRY_PROXY_REMOTEURL： 镜像上游地址

• REGISTRY_PROXY_TTL： 镜像过期时间

  客户端用法

正常使用即可：

sudo vim /etc/docker/daemon.json
{
  ...
  "insecure-registries": ["192.168.1.30:5000"],
    "registry-mirrors": [
    "http://192.168.1.30:5000"
  ]
  ...
}
