+title: docker pull使用代理
+createTime: 2026/04/04 14:28:00
+tags:
+  - Docker
+  - Proxy
+---
+
+## 问题现象
+
+当 Docker 所在的环境需要通过代理服务器和互联网连通时，直接拉取镜像会遭遇失败：
+
+```bash
+$ docker pull busybox
+Using default tag: latest
+Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled
+while waiting for connection (Client.Timeout exceeded while awaiting headers)
+```
+
+## 原因分析
+
+拉取镜像是 **docker daemon** 的职责，而不是 docker 客户端。因此，仅仅在 shell 中设置 `HTTP_PROXY` 环境变量是不够的，我们需要让 docker daemon 知道代理服务器的存在。
+
+由于 docker daemon 由 **systemd** 管理，所以需要在 systemd 配置中设置代理环境变量。
+
+## 解决方案
+
+### 1. 创建 systemd 配置目录
+
+```bash
+sudo mkdir -p /etc/systemd/system/docker.service.d
+```
+
+### 2. 创建代理配置文件
+
+新建文件 `/etc/systemd/system/docker.service.d/http-proxy.conf`：
+
+```ini
+[Service]
+Environment="HTTP_PROXY=http://proxy.example.com:port"
+Environment="HTTPS_PROXY=http://proxy.example.com:port"
+```
+
+:::tip
+如果代理服务器需要认证，格式为：`http://username:password@proxy.example.com:port`
+:::
+
+### 3. 配置私有仓库绕过代理（可选）
+
+如果有私有镜像仓库需要直连，添加 `NO_PROXY` 配置：
+
+```ini
+[Service]
+Environment="HTTP_PROXY=http://proxy.example.com:port"
+Environment="HTTPS_PROXY=http://proxy.example.com:port"
+Environment="NO_PROXY=your-registry.com,10.10.10.10,*.example.com"
+```
+
+多个地址用逗号分隔，支持通配符 `*`。如果设置 `NO_PROXY=*`，则所有请求都不通过代理。
+
+### 4. 重载配置并重启 Docker
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl restart docker
+```
+
+### 5. 验证配置
+
+检查环境变量是否正确配置：
+
+```bash
+sudo systemctl show --property=Environment docker
+```
+
+也可以通过 `docker info` 查看代理配置是否生效。
+
+## 常见误区
+
+Docker 官方有一篇关于[配置代理的文档](https://docs.docker.com/network/proxy/#configure-the-docker-client)，但那篇文档讲的是如何给**运行中的容器**配置代理环境变量，而不是给 docker daemon 配置代理来拉取镜像。如果按照那篇文档在 `~/.docker/config.json` 中配置，是无法解决拉取镜像超时的问题的。
+
+## 总结
+
+- 拉取镜像是 docker daemon 的职责
+- 需要在 systemd 层面配置 `HTTP_PROXY` 和 `HTTPS_PROXY` 环境变量
+- 配置路径：`/etc/systemd/system/docker.service.d/http-proxy.conf`
+- 配置完成后需要执行 `daemon-reload` 和 `restart docker`
+
