docker的3种网络代理配置

dockerd代理

docker pull由守护进程dockerd执行，代理配置dockerd中。

mkdir -p /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/proxy.conf
[Service]
Environment="HTTP_PROXY=http://xxx:xxx"
Environment="HTTPS_PROXY=http://xxx:xxx"
Environment="NO_PROXY=localhost,127.0.0.1,.xxx.com"

systemctl daemon-reload
systemctl restart docker

container代理

容器运行阶段和docker login走代理，Docker 17.07及以上版本生效。

vim ~/.docker/config.json
{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://xxx:xxx",
     "httpsProxy": "http://xxx:xxx",
     "noProxy": "localhost,127.0.0.1,.xxx.com"
   }
 }
}

docker build代理

docker build . --build-arg "HTTP_PROXY=http://xxx:xxx" --build-arg "HTTPS_PROXY=http://xxx:xxx" --build-arg "NO_PROXY=localhost,127.0.0.1,.xxx.com" -t xxx:xxx
