问题

Docker拉镜像的时候出现Error response from daemon: Get “https://registry-1.docker.io/v2/”: context deadline exceeded.
如果有魔法，基本不会出现这个问题

解决

打开Docker Desktop
Setting——>Docker Engine

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "debug": false,
  "experimental": false,
  "features": {
    "buildkit": true
  },
  "insecure-registries": [],
  "registry-mirrors": [
    "http://hub-mirror.c.163.com",
        "https://mirrors.tuna.tsinghua.edu.cn",

        "https://docker.m.daocloud.io",
        "https://docker.awsl9527.cn"
  ]
}
