问题

国内互联网环境状况堪忧。最近连国内各大docker镜像源都用不了。拉取Docker镜像一直失败。尝试用HTTP代理也经常报错。发现还是socks5代理好用。

代理设置

mkdir -p /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/http-proxy.conf

往 /etc/systemd/system/docker.service.d/http-proxy.conf 文件添加内容：

[Service]
Environment="HTTP_PROXY=socks5://user:pass@127.0.0.1:1080"
Environment="HTTPS_PROXY=socks5://user:pass@127.0.0.1:1080"

重启docker

systemctl daemon-reload
systemctl restart docker

查看环境变量:

sudo systemctl show --property=Environment docker

群晖 Container Manager 配置代理

mkdir -p /etc/systemd/system/pkg-ContainerManager-dockerd.service.d
vi /etc/systemd/system/pkg-ContainerManager-dockerd.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=socks5://192.168.1.3:10808"
Environment="HTTPS_PROXY=socks5://192.168.1.3:10808"
Environment="NO_PROXY=localhost,127.0.0.1"

systemctl daemon-reload
systemctl restart pkg-ContainerManager-dockerd.service

systemctl show --property=Environment pkg-ContainerManager-dockerd.service

另外如果要在 Docker 容器内通过代理访问网络，你可以在运行 Docker 容器时，设置环境变量来指定代理，例如：

docker run -e http_proxy=http://your-proxy:port \
           -e https_proxy=http://your-proxy:port \
           -e no_proxy=localhost,127.0.0.1 \
           your-image
