Docker设置代理，docker pull 代理

docker pull /push 的代理被 systemd 接管，所以需要设置 systemd

mkdir -p /etc/systemd/system/docker.service.d
touch /etc/systemd/system/docker.service.d/proxy.conf
vi /etc/systemd/system/docker.service.d/proxy.conf

编辑proxy.conf文件

# proxy.conf
[Service]
Environment="HTTP_PROXY=http://172.30.172.136:4780"
Environment="HTTPS_PROXY=http://172.30.172.136:4780"
Environment="NO_PROXY=localhost,127.0.0.1,.example.com,172.16.0.0/12"

重启docker服务

sudo systemctl daemon-reload
sudo systemctl restart docker
# 可以看到设置的环境变量
sudo systemctl show docker | grep Environment
