### 1 介绍dockerhub为什么无法访问 ###

最近许多群友都询问为什么无法访问Docker镜像仓库，于是我也尝试去访问，结果果然无法访问。

大家的第一反应就是给墙了，通过ping检测红的很可怕。

实际上是DNS被污染了，导致很多用户都无法访问。至于什么是DNS污染，大家可以自行查询，这里主要讲解怎么解决dockerhub无法访问的问题。

### 2 解决办法 ###

由于无法访问，导致我们运维人员和开发者使用docker镜像变得极其不方便，然而我们可以使用下面几种方法来解决这个问题。

#### 2.1 使用魔法 ####

（这里就不展开说了，大家懂的都懂）

#### 2.2 使用国内镜像加速 ####

常见的国内加速服务：

*  科大镜像：[https://docker.mirrors.ustc.edu.cn][https_docker.mirrors.ustc.edu.cn]
 *  网易：[http://hub-mirror.c.163.com][http_hub-mirror.c.163.com]
 *  阿里云：https://<你的ID>.mirror.aliyuncs.com

废话不多说，直接上命令

##### 2.2.1 docker配置： #####

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["镜像加速地址"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker
    
    # 示例
    sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["https://eph8xfli.mirror.aliyuncs.com"]  # 这是博主自己的阿里云镜像加速地址，大家可以更换为自己的
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

阿里云官网也有不同操作系统的操作文档，大家可以自行查阅

##### 2.2.2 containerd配置： #####

包括K8S镜像加速

vim /etc/containerd/config.toml
          [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
    
            [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
              endpoint = ["https://docker.mirrors.ustc.edu.cn","http://hub-mirror.c.163.com"]
            [plugins."io.containerd.grpc.v1.cri".registry.mirrors."gcr.io"]
              endpoint = ["https://gcr.mirrors.ustc.edu.cn"]
            [plugins."io.containerd.grpc.v1.cri".registry.mirrors."k8s.gcr.io"]
              endpoint = ["https://gcr.mirrors.ustc.edu.cn/google-containers/"]
            [plugins."io.containerd.grpc.v1.cri".registry.mirrors."quay.io"]
              endpoint = ["https://quay.mirrors.ustc.edu.cn"]
            [plugins."io.containerd.grpc.v1.cri".registry.mirrors."ghcr.io"]
              endpoint = ["https://ghcr.dockerproxy.com"]

#### 2.3 使用博主个人镜像仓库 ####

本镜像仓库在阿里云，主要包含K8S相关镜像。如果大家有所需求，可以联系博主增加相关镜像。

镜像每天持续同步更新，目前有80+仓库，包含新版和常用镜像版本。

##### 2.3.1 目前有如下镜像仓库，后续会陆续增加 #####

##### 2.3.2 使用方式 #####

docker.elastic.co/kibana/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name}
    quay.io/csiaddons/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name}
    k8s.gcr.io/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name}
    ....

##### 2.3.3 拉取镜像 #####
