一、安装部署Calico
1、创建工作目录
mkdir -p /opt/cni/bin
tar zxvf cni-plugins-linux-amd64-v0.8.6.tgz -C /opt/cni/bin
cd /opt/cni/bin
scp ./* root@192.168.112.111:/opt/cni/bin/
2、docker导入calico镜像
tar -zxvf image.tar.gz docker load < calico-cni.tar docker load -i calico-controllers.tar docker load -i calico-flexvol.tar docker load -i calico-node.tar docker load -i coredns.tar docker load -i dashboard.tar docker load -i metrics-scraper.tar docker load -i metrics-server.tar docker load -i nginx-ingress-controller.tar

4、启动容器
kubectl apply -f calico.yaml
kubectl get pods -n kube-system
等Calico Pod都Running，节点也会准备就绪
kubectl get node
NAME STATUS ROLES AGE VERSION
k8s-master1 Ready <none> 37m v1.20.4
5、授权apiserver访问kubelet
应用场景：例如kubectl logs
cat > apiserver-to-kubelet-rbac.yaml << EOF apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: annotations: rbac.authorization.kubernetes.io/autoupdate: "true" labels: kubernetes.io/bootstrapping: rbac-defaults name: system:kube-apiserver-to-kubelet rules: - apiGroups: - "" resources: - nodes/proxy - nodes/stats - nodes/log - nodes/spec - nodes/metrics - pods/log verbs: - "*" --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: system:kube-apiserver namespace: "" roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: system:kube-apiserver-to-kubelet subjects: - apiGroup: rbac.authorization.k8s.io kind: User name: kubernetes EOF kubectl apply -f apiserver-to-kubelet-rbac.yaml
二、部署Dashboard、CoreDNS
1、导入镜像
tar -zxvf coredns.tar docker load -i dashboard.tar docker load -i flannel.tar docker load -i metrics-scraper.tar docker load -i nginx-ingress-controller.tar docker load -i pause.tar
2、准备kubernetes-dashboard.yaml文件

3、部署容器
kubectl apply -f kubernetes-dashboard.yaml
kubectl get pods,svc -n kubernetes-dashboard
访问地址：https://NodeIP:30001
4、创建service account并绑定默认cluster-admin管理员集群角色
kubectl create serviceaccount dashboard-admin -n kube-system kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin kubectl describe secrets -n kube-system $(kubectl -n kube-system get secret | awk ‘/dashboard-admin/{print $1}‘)
使用输出的token登录Dashboard。
登录web页面
5、准备coredns.yaml文件

6、部署容器
kubectl apply -f coredns.yaml kubectl get pods -n kube-system NAME READY STATUS RESTARTS AGE coredns-6cc56c94bd-kf6wz 1/1 Running 0 23m
7、DNS解析测试
kubectl run -it --rm dns-test --image=busybox:1.28.4 sh
If you don‘t see a command prompt, try pressing enter. / # nslookup kubernetes Server: 10.0.0.2 Address 1: 10.0.0.2 kube-dns.kube-system.svc.cluster.local Name: kubernetes Address 1: 10.0.0.1 kubernetes.default.svc.cluster.local
