k8s部署安装

部署前先进行环境优化centos系统优化脚本

！！！注意我的系统安装时没有创建swap交换分区，所以未写关闭交换分区的内容

初始化

kubeadm init --kubernetes-version=v1.15.3 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12  --image-repository registry.aliyuncs.com/google_containers

安装网络插件

kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/canal/rbac.yaml
kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/canal/canal.yaml

安装可视化工具（强烈不建议使用在外网环境）

kubectl apply -f "https://cloud.weave.works/k8s/scope.yaml?k8s-version=$(kubectl version | base64 | tr -d '\n')&k8s-service-type=NodePort"
