Docker使用代理

方法一

创建配置文件
~/.docker/config.json
内容如下

"proxies": {
   "default": {
     "httpProxy": "socks5://127.0.0.1:1080",
     "httpsProxy": "socks5://127.0.0.1:1080",
     "noProxy": "127.0.0.0/8"
   }
}

方法二

创建配置文件和文件夹
/etc/systemd/system/docker.service.d/proxy.conf
配置文件内容如下

[Service]
Environment="http_proxy=socks5://192.168.0.1:1080"
Environment="https_proxy=socks5://192.168.0.1:1080"
Environment="no_proxy=10.0.0.0/8,172.0.0.0/8,192.168.0.0/16"  //不走代理

重启Docker服务

systemctl daemon-reload
systemctl restart docker

验证生效
1. 查看Docker服务启动时的环境变量
systemctl show docker --property Environment

2. 测试拉取镜像

Docker容器使用代理

docker run命令

docker run -e http_proxy=${http_proxy} -e https_proxy=${https_proxy}

Docker Compose
docker-compose.yml，在environment增加配置

- http_proxy=socks5://192.168.0.1:1080
- https_proxy=socks5://192.168.0.1:1080
- all_proxy=socks5://192.168.0.1:1080  //全局代理
- no_proxy=10.0.0.0/8,172.0.0.0/8,192.168.0.0/16  //不走代理
