方案 2(服务器自建): 利用 registry 或者 harbor :
下面是 reigistry 方案:
nano registry/docker-compose.yml
#version: '3' #最新版本 docker 不在需要此字段
services:
registry:
image: registry:2
ports:
- "15000:5000"
environment:
REGISTRY_PROXY_REMOTEURL: https://registry-1.docker.io # 上游源
REGISTRY_STORAGE_CACHE_BLOBDESCRIPTOR: inmemory # 内存缓存
volumes:
- ./data:/var/lib/registry
如果只是作为镜像, 就把推送功能 ban 掉. 这里推荐用简单的方式 nginx 反代 禁止其他 http method.
# 端口, 域名 都改为自己的
server {
listen 80;
server_name my-registry-domain.com;
location / {
# 仅允许 GET 请求
limit_except GET {deny all;}
proxy_pass http://localhost:15000; # 假设 Docker Registry 运行在本地的 15000 端口
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
