快速部署kubernets集群服务器 （v1.19.0-1.24.0）

k8s部署前请准备好多台centos linux 7.9服务器，以及daemon.json、hosts、calico-v3.21.yaml等文件。并将文件放置在install-k8s.yaml指定的目录，本文在yaml目录。其中，daemon.json是用来配置docker运行参数文件，请根据自己需求配置；hosts是域名指向文件，如果有DNS服务器，那么请在服务器上配置；calico-v3.21.yaml是k8s的网络组件部署配置文件。
一、在管理机上运行yaml文件安装docker、kubeadm、kubectl、kubelet等相关程序，配置每台服务器。
运行install-k8s.yaml
二、在每台机器上下载images文件
docker pull registry.aliyuncs.com/google_containers/pause:3.2 docker pull registry.aliyuncs.com/google_containers/coredns:1.7.0 docker pull registry.aliyuncs.com/google_containers/kube-scheduler:v1.19.0 docker pull registry.aliyuncs.com/google_containers/kube-apiserver:v1.19.0 docker pull registry.aliyuncs.com/google_containers/kube-controller-manager:v1.19.0 docker pull registry.aliyuncs.com/google_containers/kube-proxy:v1.19.0 docker pull registry.aliyuncs.com/google_containers/etcd:3.4.13-0 docker pull registry.aliyuncs.com/google_containers/kube-controllers docker pull registry.aliyuncs.com/google_containers/node docker tag registry.aliyuncs.com/google_containers/kube-controllers calico/kube-controllers:v3.21.0 docker tag registry.aliyuncs.com/google_containers/node calico/node:v3.21.0 docker pull calico/node docker pull calico/cni docker tag calico/node calico/node:v3.21.0 docker tag calico/cni calico/cni:v3.21.0
docker tag calico/node calico/node:v3.21.0 docker tag calico/cni calico/cni:v3.21.0 docker tag registry.aliyuncs.com/google_containers/kube-apiserver:v1.19.0 k8s.gcr.io/kube-apiserver:v1.19.0 docker tag registry.aliyuncs.com/google_containers/kube-controller-manager:v1.19.0 k8s.gcr.io/kube-controller-manager:v1.19.0 docker tag registry.aliyuncs.com/google_containers/kube-scheduler:v1.19.0 k8s.gcr.io/kube-scheduler:v1.19.0 docker tag registry.aliyuncs.com/google_containers/kube-proxy:v1.19.0  k8s.gcr.io/kube-proxy:v1.19.0 docker tag registry.aliyuncs.com/google_containers/pause:3.2 registry.aliyuncs.com/google_containers/pause:3.2 docker tag registry.aliyuncs.com/google_containers/etcd:3.4.13-0 k8s.gcr.io/etcd:3.4.13-0 docker tag registry.aliyuncs.com/google_containers/coredns:1.7.0 k8s.gcr.io/coredns:1.7.0 docker tag registry.aliyuncs.com/google_containers/pause:3.2 k8s.gcr.io/pause:3.2
三、在master上执行init.yaml生成配置文件
kubeadm config print init-defaults >init.yaml
kubeadm init --config init.yaml
如下相关位置按个人需求修改

四、生成k8s的配置文件，并将配置文件拷贝到各个服务器节点
mkdir -p ~/.kube cp -i /etc/kubernetes/admin.conf ~/.kube/config
scp root@192.168.126.152:/root/.kube/config yaml/.
scp yaml/config root@192.168.126.153:/root/.kube/config scp yaml/config root@192.168.126.154:/root/.kube/config
五、部署网络组件calico
kubectl apply -f calico-v3.21.yaml
六、添加节点到集群
kubeadm join 192.168.126.152:6443 --token abcdef.0123456789abcdef     --discovery-token-ca-cert-hash sha256:aeef49daa2ccf3bbff72d7c43a9103a69902588796bc1b097433e6a4c8f80ca8 --v=5
五、如果在安装kubelet、kubeadm、kubeclt后加入节点到集群发生故障，执行以下命令： rm -rf /etc/kubernetes/pki/ca.crt rm -rf /etc/kubernetes/kubelet.conf kubeadm reset -f iptables -F && iptables -t nat -F && iptables -t mangle -F && iptables -X ipvsadm -C kubeadm join 192.168.126.152:6443 --token abcdef.0123456789abcdef     --discovery-token-ca-cert-hash sha256:aeef49daa2ccf3bbff72d7c43a9103a69902588796bc1b097433e6a4c8f80ca8 --v=5
