解决 Docker Hub 国内无法访问的方法（Docker 镜像下载加速）

docker配置
修改配置文件

vim /etc/docker/daemon.json

配置内容如下：

{
    "data-root": "/data/docker",
    "exec-opts": ["native.cgroupdriver=systemd"],
    "registry-mirrors": [
    "https://9cpn8tt6.mirror.aliyuncs.com",
    "https://dockerproxy.com",
    "https://hub-mirror.c.163.com",
    "https://mirror.baidubce.com",
    "https://ccr.ccs.tencentyun.com"
  ]
}

3.重启docker引擎

#重载unit配置文件
systemctl daemon-reload
systemctl restart docker
systemctl status docker

wget

https://github.com/Mirantis/cri-dockerd/releases/download/v0.3.8/cri-dockerd-0.3.8-3.el7.x86_64.rpm

#安装
rpm -ivh cri-dockerd-0.3.8-3.el7.x86_64.rpm

修改/usr/lib/systemd/system/cri-docker.service中ExecStart那一行，制定用作Pod的基础容器镜像(pause)

ExecStart=/usr/bin/cri-dockerd --pod-infra-container-image=registry.k8s.io/pause:3.9 --container-runtime-endpoint fd://

vi /usr/lib/systemd/system/cri-docker.service

修改

--pod-infra-container-image=registry.k8s.io/pause:3.9 为
--pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.9

重启cri-docker

systemctl daemon-reload
systemctl restart cri-docker

安装kubernetes
1 下载 kubelet kubeadm kubectl
在一台有网的机器执行：

# 配置镜像源
# k8s源镜像源准备(社区版yum源，注意区分版本)
cat <<EOF | tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://pkgs.k8s.io/core:/stable:/v1.30/rpm/
enabled=1
gpgcheck=1
gpgkey=https://pkgs.k8s.io/core:/stable:/v1.30/rpm/repodata/repomd.xml.key
EOF

# yum下载（不安装）
yum -y install --downloadonly --downloaddir=/data/software/k8s-package kubeadm-1.30.0-150500.1.1 kubelet-1.30.0-150500.1.1 kubectl-1.30.0-150500.1.1

本文只贴核心

```bash
kubeadm init --kubernetes-version=v1.30.0 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.0.20  --cri-socket unix:///var/run/cri-dockerd.sock --image-repository registry.aliyuncs.com/google_containers  --upload-certs

其他机子

kubeadm join 192.168.0.20:6443 --token g4y5kb.zbx4xgqn4uzdwdlj \
        --discovery-token-ca-cert-hash sha256:742f87a0c870c0922afacdc3f30f5686d82a18380f8b8113f21be90341d24fa2  \
        --cri-socket unix:///var/run/cri-dockerd.sock
