kubernetes 开发环境安装

省安装步骤，本次使用 docker-for-mac 测试

build docker

创建 docker 镜像

docker build -t hzw/nodebook:v1 .
docker images | grep nodebook

运行 docker, 测试是否可用


docker run --name nodebookv1 -p 3000:3000 hzw/nodebook:v1

使用 kubectl create 来部署项目

kubectl create -f  notebook-istio-deplyment.yaml

查看 service 和 development

kubectl get deployments
kubectl get service
kubectl describe service nodebook
kubectl get pod -l app=nodebook -o wide

请求服务，查看服务端响应

curl http://localhost:3000/version

使用 kubectl run 命令创建 Deployment 来管理 Pod。

kubectl run nodebook --image=hzw/nodebook:v1 --port=3000
kubectl get deployments
kubectl get pods

使用 kubectl expose 命令将 Pod 暴露到外部环境：

kubectl expose deployment nodebook --type=LoadBalancer --port=3000 --target-port=3000
kubectl get services
kubectl describe service nodebook

扩展实例

kubectl scale deployments/nodebook --replicas=4
kubectl get pods

更新 image

kubectl set image deployment/nodebook nodebook=hzw/nodebook:v2

删除 deployment

kubectl delete service nodebook
kubectl delete deployment notebook-deployment
kubectl get pods

创建 deployment

kubectl create -f  nodebook-deployment.yaml
kubectl get deployments

升级

kubectl apply -f nodebook-deployment.yaml
kubectl rollout status deployment/nodebook-deployment

查看历史

kubectl rollout history deployment/nodebook-deployment

查看详情

kubectl describe deployment nodebook-deployment

回滚

kubectl rollout undo deployment nodebook-deployment
