CentOS7 docker网络代理设置

一、为docker服务创建一个内嵌的systemd目录
$ mkdir -p /etc/systemd/system/docker.service.d

二、创建/etc/systemd/system/docker.service.d/http-proxy.conf文件，并添加HTTP_PROXY环境变量

[Service]
Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=https://[proxy-addr]:[proxy-port]/"

或

[Service]
Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=https://[proxy-addr]:[proxy-port]/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"

三、更新配置
$ systemctl daemon-reload
四、重启docker
$ systemctl restart docker
