minikube操作教程

安装

官方文档
amd64

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

arm64

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-arm64
sudo install minikube-linux-arm64 /usr/local/bin/minikube

• 没安装 kubectl 可以使用 minikube kubectl -- 代替

启动你的集群

开始

minikube start --force
kubectl get po -A
minikube version

web界面

minikube dashboard --port=19888
# eg: http://127.0.0.1:19888/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

kubectl安装

部署应用程序

services

kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0
kubectl expose deployment hello-minikube --type=NodePort --port=8080

kubectl get services hello-minikube

minikube service hello-minikube
or
kubectl port-forward service/hello-minikube 7080:8080

loadBalancer

kubectl create deployment balanced --image=kicbase/echo-server:1.0
kubectl expose deployment balanced --type=LoadBalancer --port=8080

minikube tunnel

http://127.0.0.1:TUNNEL_PORT

LoadBalancer

minikube tunnel
kubectl create deployment hello-minikube1 --image=kicbase/echo-server:1.0
kubectl expose deployment hello-minikube1 --type=LoadBalancer --port=8080
kubectl get svc
http://REPLACE_WITH_EXTERNAL_IP:8080

minikube tunnel --cleanup

配置集群

文档

创建一个 Kubernetes 集群

minikube version
minikube start
kubectl version
kubectl cluster-info
kubectl get nodes

部署一个应用程序

kubectl create deployment nginx --image=nginx:latest
kubectl get deployments
kubectl proxy # 和minikube dashboard一样
curl http://localhost:8001/version

探索你的应用程序

kubectl get pods
kubectl describe pods
kubectl logs $POD_NAME
kubectl exec $POD_NAME -- env
kubectl exec -ti $POD_NAME -- bash
curl localhost:80
exit

公开你的应用程序

kubectl get pods
kubectl get services
kubectl expose deployment/nginx --type="NodePort" --port 80
kubectl get services
kubectl describe services/nginx
curl $(minikube ip):$NODE_PORT

kubectl describe deployment
kubectl get pods -l app=nginx
kubectl get services -l app=nginx
kubectl label pods $POD_NAME version=v1
kubectl describe pods $POD_NAME
kubectl get pods -l version=v1
kubectl delete service -l app=nginx
kubectl get services

扩展你的应用程序

kubectl expose deployment/nginx --type="NodePort" --port 80
kubectl get deployments
kubectl get rs
kubectl scale deployments/nginx --replicas=4
kubectl get pods -o wide
kubectl describe deployments/nginx

Load Balancing

kubectl describe services/nginx
curl $(minikube ip):$NODE_PORT

kubectl scale deployments/nginx --replicas=2
kubectl get deployments
kubectl get pods -o wide

更新你的应用程序

kubectl get deployments
kubectl get pods
kubectl describe pods
kubectl set image deployments/nginx nginx=nginx:v2
kubectl get pods
kubectl describe services/nginx
kubectl rollout status deployments/nginx
kubectl describe pods
# 回滚
kubectl set image deployments/nginx nginx=nginx:v10
kubectl get deployments
kubectl get pods
kubectl describe pods
kubectl rollout undo deployments/nginx
kubectl get pods
kubectl describe pods
