分享:自建Docker镜像

2024年6月,中国大陆多个Docker镜像因监管要求关闭服务,包括中科大、上海交大等教育机构和云服务商的镜像站。此举旨在维护网络生态安全,影响范围广泛。

在各个Docker镜像重新开放之前,无法拉去镜像给日常开发者带来了诸多不便,为了能够方便自己能够便捷拉取镜像。站住通过Github项目Docker-proxy搭建了Docker镜像代理拉取站点。

这里分享一下Docker-proxy大致的搭建方式,需要注意的是,Docker-proxy需要在国外服务器(能访问docker源的服务器)上搭建。同时该服务器没有被墙,或者你的域名国内可以访问。需要提前安装好docker应用,不同linux发行版的安装方式不同,这一步可自行按需进行。

首先创建路径

mkdir docker-proxy

cd docker-proxy

随后创建docker-compose.yaml

vim docker-compose.yaml

填入下面的代码

services:

  ## docker hub

  dockerhub:
    container_name: reg-docker-hub

    volumes:
      - ./registry/data:/var/lib/registry

保存docker-compose.yaml后,在相同目录下,下载这个压缩包(config.zip)并把里面的接个文件放置在和docker-compose.yaml相同的目录路径下。

随后部署Docker-proxy容器,等待完成

docker compose up -d

完成后,不同的镜像在不同的端口

ui 端口50000

docker-hub 端口51000

ghcr 端口52000

grc 端口 53000

k8s-grc 端口54000

k8s 端口55000

quay 端口56000

mrc 端口57000

elastic 端口58000

可以通过放通端口,使用ip+端口的方式访问对应镜像代理,也可以使用反代+https访问来体高安全性。

目前站主搭建的代理镜像使用量并不大,如果有学习、学术科研需求的朋友需要使用,可以留言评论获取。
