Docker 代理

Docker 守护进程代理 (docker pull)

mkdir -p /etc/systemd/system/docker.service.d
sudo tee /etc/systemd/system/docker.service.d/http-proxy.conf > /dev/null <<'EOF'
[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"
EOF
systemctl daemon-reload
systemctl restart docker

Image 构建代理

docker image build \
    --build-arg HTTP_PROXY="http://127.0.0.1:7890" \
    --build-arg HTTPS_PROXY="http://127.0.0.1:7890" \
    --build-arg NO_PROXY="localhost,127.0.0.1" \
    -f Dockerfile -t my-app:v1.0 .

Container 运行环境代理 (docker run)

1. 命令参数（推荐，单次生效）
   1. docker run

      docker container run -it \
          -e HTTP_PROXY="http://127.0.0.1:7890" \
          -e HTTPS_PROXY="http://127.0.0.1:7890" \
          -e NO_PROXY="localhost,127.0.0.1" \
          --rm \
          --name=alma \
          almalinux:latest /bin/bash
      

   2. docker compose

      services:
          alma:
          image: almalinux:latest
          container_name: alma
          environment:
          - HTTP_PROXY=http://127.0.0.1:7890
          - HTTPS_PROXY=http://127.0.0.1:7890
          - NO_PROXY=localhost,127.0.0.1
          stdin_open: true   # 对应 -i
          tty: true          # 对应 -t
          restart: "no"
      

2. 配置文件 (不常用)
   位置：~/.docker/config.json（针对当前用户）

   {
       "proxies": {
           "default": {
               "httpProxy": "http://127.0.0.1:7890",
               "httpsProxy": "http://127.0.0.1:7890",
               "noProxy": "http://127.0.0.1:7890"
           }
       }
   }
