docker设置代理服务器

查看docker.service文件所在的路径：

[root@k8s-test ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
  Drop-In: /usr/lib/systemd/system/docker.service.d
           └─proxy.conf
   Active: active (running) since Sat 2025-02-08 16:19:45 CST; 4min 54s ago
     Docs: https://docs.docker.com
 Main PID: 229477 (dockerd)
    Tasks: 179
   Memory: 4.3G

由于我已经设置好了代理，所以这里能看到docker服务已经加载了配置文件 proxy.conf

在目录 /usr/lib/systemd/system/ 下新建文件夹docker.service.d，并新增配置文件proxy.conf

sudo mkdir -p /usr/lib/systemd/system/docker.service.d
sudo touch /usr/lib/systemd/system/docker.service.d/proxy.conf

编辑配置文件内容

[Service]
Environment="HTTP_PROXY=http://127.0.0.1:8080/"
Environment="HTTPS_PROXY=http://127.0.0.1:8080/"
Environment="NO_PROXY=localhost,127.0.0.1,.example.com"

重启docker服务

systemctl daemon-reload
systemctl restart docker
