1. 创建集群
#The client version is the kubectl version; the server version is the Kubernetes version installed on the master. You can also see details about the build.
kubectl version
#查看集群信息
kubectl cluster-info
#查看节点信息
kubectl get nodes
---
2. 部署应用
#指定deployment名字和镜像的url
kubectl create deployment kubernetes-bootcamp --image=gcr.io/google-samples/kubernetes-bootcamp:v1
#显示deployment
kubectl get deployments
#创建proxy
kubectl proxy
#使用curl访问
curl http://localhost:8001/version
---
3. 应用交互
#显示存在的pod
kubectl get pods
#显示pod详细信息
kubectl describe pods
#proxy
kubectl proxy
#导出容器name
export POD_NAME=$(kubectl get pods -o go-template --template '\n')
echo Name of the Pod: $POD_NAME
#curl
curl http://localhost:8001/api/v1/namespaces/default/pods/$POD_NAME/proxy/
#查看容器日志
kubectl logs $POD_NAME
#查看容器环境变量
kubectl exec $POD_NAME env
#执行bash session在容器中
kubectl exec -ti $POD_NAME bash
#显示执行的js脚本
cat server.js
#在容器中访问服务
curl localhost:8080
#退出
exit
4. 暴露应用服务
kubectl get services
#将服务暴露出去
kubectl expose deployment/kubernetes-bootcamp --type="NodePort" --port 8080
#查看服务详细信息
kubectl describe services/kubernetes-bootcamp
#获取端口
export NODE_PORT=$(kubectl get services/kubernetes-bootcamp -o go-template='')
echo NODE_PORT=$NODE_PORT
#curl测试
curl $(minikube ip):$NODE_PORT
#获取pod name
export POD_NAME=$(kubectl get pods -o go-template --template '\n') echo Name of the Pod: $POD_NAME
#给服务打新的标签
kubectl label pod $POD_NAME app=v1
#删除服务
kubectl delete service -l run=kubernetes-bootcamp
#确认服务在运行
kubectl get services
#测试能访问
curl $(minikube ip):$NODE_PORT
#进行服务执行
kubectl exec -ti $POD_NAME curl localhost:8080
5. 对服务进行扩容缩容
#查看有多少replica
kubectl get deployments
kubectl get rs
#扩容
kubectl scale deployments/kubernetes-bootcamp --replicas=4
#查看4个节点ip
kubectl get pods -o wide
#查看详细信息
kubectl describe deployments/kubernetes-bootcamp
kubectl describe services/kubernetes-bootcamp
#将port暴露出
export NODE_PORT=$(kubectl get services/kubernetes-bootcamp -o go-template='')
echo NODE_PORT=$NODE_PORT
#访问
curl $(minikube ip):$NODE_PORT
#缩容
kubectl scale deployments/kubernetes-bootcamp --replicas=2
#查看状态
kubectl get pods -o wide
6. 滚动更新
kubectl get deployments
kubectl get pods
kubectl describe pods
kubectl set image deployments/kubernetes-bootcamp kubernetes-bootcamp=jocatalin/kubernetes-bootcamp:v2
kubectl describe services/kubernetes-bootcamp
export NODE_PORT=$(kubectl get services/kubernetes-bootcamp -o go-template='')
echo NODE_PORT=$NODE_PORT
curl $(minikube ip):$NODE_PORT
kubectl rollout status deployments/kubernetes-bootcamp
kubectl describe pods
kubectl set image deployments/kubernetes-bootcamp kubernetes-bootcamp=gcr.io/google-samples/kubernetes-bootcamp:v10
kubectl get deployments
kubectl get pods
kubectl describe pods
kubectl rollout undo deployments/kubernetes-bootcamp
kubectl get pods
kubectl describe pods
