1.准备 Linux 机器

2.google api受限下载 KubeKey

export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh -
chmod +x kk

3.开始安装

./kk create cluster [--with-kubernetes version] [--with-kubesphere version]
./kk create cluster --with-kubernetes v1.17.9 --with-kubesphere v3.0.0

4.验证结果

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

5.K8S常用命令

kubectl create -f pod_nginx.yml //创建pod

kubectl apply -f nginx-pod.yaml //通过apply创建pod会记录pod最近的修改记录

kubectl delete -f pod_nginx.yml //删除pod

kubectl delete pod PODNAME --force --grace-period=0 //强制删除

kubectl scale rc nginx --replicas=2 //扩展pods 

kubectl set image deploy kubernetes-bootcamp kubernetes-bootcamp=jocatalin/kubernetes-bootcamp:v2 //更新镜像版本

kubectl rollout status deployment kubernetes-bootcamp  //查看更新的状态

kubectl rollout undo deploy kubernetes-bootcamp //执行更新回退

journalctl -f -u kube-proxy //查看对应日志是否为info级 

kubectl logs wordpress-test-df8f45f5b-6gnjz -f   //跟踪查看pods 日志

kubectl run php-apache --image=k8s.gcr.io/hpa-example --requests=cpu=200m --expose --port=80  // 创建自动扩展pod

kubectl autoscale deployment php-apache --cpu-percent=50 --min=1 --max=10 // 自动扩展pod

kubectl get pods //查看pods

kubectl get pods -o wide //查看pods运行的相信信息

kubectl exec -it nginx bash //进入容器

kubectl describe pods nginx //打印描述pods

kubectl port-forward nginx 8080:80 //对pods进行端口映射

kubectl expose pods nginx-pod --type=NodePort  //创建NodePort service

kubectl expose deploy kubernetes-bootcamp --type="NodePort" --target-port=8080 --port=80 //创建NodePort暴露服务端口

kubectl label node w1 hardware=good //给node打标签

kubectl get pods --show-labels  //显示pods labels

kubectl run busybox --rm=true --image=busybox --restart=Never --tty -i  //启动测试容器用以测试容器
