查看 /etc/systemd/system/docker.service.d/http-proxy.conf 文件（沒有則新建），查看自定義 Docker 服務的代理設置

輸入內容

[Service]
Environment="HTTP_PROXY=socks5://10.211.13.214:7890"
Environment="HTTPS_PROXY=socks5://10.211.13.214:7890"
Environment="NO_PROXY=localhost,127.0.0.1"

配置完成后重啟Docker

systemctl daemon-reload
systemctl restart docker

驗證代理生效

systemctl show docker --property Environment

配置 Docker 的鏡像加速

/etc/docker/daemon.json

sudo mkdir -p /etc/docker  # 確保目錄存在
sudo vim /etc/docker/daemon.json

寫入（這里有很多鏡像源）

{"registry-mirrors": ["https://do.nark.eu.org","https://dc.j8.work","https://docker.m.daocloud.io","https://dockerproxy.com","https://docker.mirrors.ustc.edu.cn","https://docker.nju.edu.cn","https://6k0ibwjk.mirror.aliyuncs.com"]
} 

避免過多鏡像源

建議保留 2-3 個穩定的鏡像源

{"registry-mirrors": ["https://6k0ibwjk.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn"]
}

配置完成后重啟Docker

systemctl daemon-reload
systemctl restart docker

驗證安裝

 docker run hello-world

出現

Hello from Docker!
