docker 镜像代理配置

image-20240926105236984

因为Docker 官方源很早之前就被官方封禁了,国内拉取 Docker 镜像必须依赖国内镜像源:比如网易、中科大、阿里等。
但是最近大家应该都遇到了无法拉取 Docker 镜像的问题,即使换了国内源也会拉取失败。就我目前的测试来看:国内的 Docker 镜像源疑似集体停止服务。而且这一切发生得静悄悄,没有任何相关公告。 虽然可以通过部分镜像源拉取历史版本(阿里 2022之前的版本镜像),为了从根本解决问题。
本文,将为docker配置上代理(梯子),解决docker镜像拉取问题,获取最新镜像文件。

准备代理IP

可以某宝购买,也可以是自己搭建的TZ;这里介绍 从 clash 中分享出来的代理,开启来自局域网的连接。

为docker 配置代理

  • 修改文件vim /etc/docker/daemon.json ,配置内容为下文,没有则新建

删除之前配置的国内镜像源,配置docker 官方镜像链接。这里直接粘贴进去即可。

 {
     "registry-mirrors": ["https://hub.docker.com"],
     "insecure-registries": ["http://hub.WinJay.cn"],
     "storage-driver": "overlay2",
     "log-driver":"json-file",
     "log-opts": {"max-size":"5m", "max-file":"3"}
 }

创建代理文件

mkdir /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/proxy.conf
[Service]
# 172.16.0.88为代理服务器IP地址
Environment="HTTP_PROXY=http://172.16.0.88:7890"
Environment="HTTPS_PROXY=http://172.16.0.88:7890"
Environment="NO_PROXY=localhost,127.0.0.1"

加载配置、重启docker

# 加载配置
systemctl daemon-reload
# 重启docker
systemctl restart docker
# 查看代理配置是否生效
systemctl show --property=Environment docker
##---打印内容---
Environment=HTTP_PROXY=http://172.16.0.88:7890 HTTPS_PROXY=http://172.16.0.88:7890
