docker pull 拉取镜像报错“Error response from daemon: Get “https://registry-1.docker.io/v2“的解决办法

---

1、事故现场

[root@zyl ~]# docker pull python:3.9.20
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)

2、解决方法

设置可访问的镜像源;

• 编辑/etc/docker/daemon.json文件

vi /etc/docker/daemon.json

• 添加可用镜像源

{
  "registry-mirrors": [
        "https://docker.rainbond.cc"
  ]
}

• 重启docker

systemctl daemon-reload
systemctl restart docker
