Docker 添加代理

1. 创建 override 目录：

sudo mkdir -p /etc/systemd/system/docker.service.d

2. 创建代理文件：

sudo nano /etc/systemd/system/docker.service.d/http-proxy.conf

3. 写入内容（根据你 Clash 的端口替换）：

[Service]
Environment="HTTP_PROXY=http://127.0.0.1:7890"
Environment="HTTPS_PROXY=http://127.0.0.1:7890"
Environment="NO_PROXY=localhost,127.0.0.1"

4. 生效配置

sudo systemctl daemon-reload
sudo systemctl restart docker

5. 验证

docker info | grep -i proxy
