docker镜像加速

近期，国内云计算和容器技术社区面临了一项挑战：多个镜像加速站点被关闭。这些加速站点原本为开发者和企业提供了快速访问和下载海外 Docker 镜像的能力,以下是一些可以用的镜像地址

腾讯云镜像加速器地址：https://mirror.ccs.tencentyun.com
中国科学技术大学：https://docker.mirrors.ustc.edu.cn
Docker官方镜像（中国区）镜像加速：https://registry.docker-cn.com
网易云镜像加速器地址：http://hub-mirror.c.163.com
南京大学镜像加速器地址：https://docker.nju.edu.cn

阿里云镜像加速器地址：https://xxxxxx.mirror.aliyuncs.com
Daocloud 镜像加速器地址：https://docker.m.daocloud.io

1、配置阿里云镜像加速器
阿里云提供了免费使用的镜像加速服务。以下是具体的配置步骤：
登录到阿里云控制台 https://cr.console.aliyun.com/
进入“镜像中心”，点击左侧菜单中的“镜像加速器”。
将页面中展示的加速器地址记下来，例如 https://xxxxxx.mirror.aliyuncs.com。

docker info | grep -A1 "Registry Mirrors"

配置多个镜像地址

# cat /etc/docker/daemon.json
{
  "registry-mirrors": [
        "https://i3nc9nvv.mirror.aliyuncs.com",
        "https://docker.m.daocloud.io",
        "https://dockerhub.timeweb.cloud"
    ],
  "insecure-registries": ["harbor-local.kubernets.cn"],
  "log-driver":"json-file",
  "log-opts": {
    "max-size":"500m",
    "max-file":"3"
  }
}
