编辑Dockerfile

FROM openjdk:8-jre-alpine  


COPY springboot-web-demo-1.0-SNAPSHOT.jar /springboot-web.jar


ENTRYPOINT ["java", "-jar", "/springboot-web.jar"]

 

打出镜像

 

docker build -t springboot-web:v1 .

 

根据镜像启动容器

docker run -it springboot-web:v1

 

给镜像打tag 并上传harbor

docker tag springboot-web:v1 harbor.pdabc.com/kubernetes/springboot-web:v1

docker push harbor.pdabc.com/kubernetes/springboot-web:v1

 

在master上创建springboot-web.yaml

#deploy
apiVersion: apps/v1
kind: Deployment
metadata:
  name: springboot-web-demo
spec:
  selector:
    matchLabels:
      app: springboot-web-demo
  replicas: 1
  template:
    metadata:
      labels:
        app: springboot-web-demo
    spec:
      containers:
      - name: springboot-web-demo
        image: harbor.pdabc.com/kubernetes/springboot-web:v1
        ports:
        - containerPort: 8080

#service
apiVersion: v1
kind: Service
metadata:
  name: springboot-web-demo
spec:
  ports:
  - port: 80
    protocol: TCP
    targetPort: 8080
  selector:
    app: springboot-web-demo
  type: ClusterIP

#ingress
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: springboot-web-demo
spec:
  rules:
  - host: springboot.pdabc.com
    http:
      paths:
      - path: /
        backend:
          serviceName: springboot-web-demo
          servicePort: 80

 

启动

kubectl apply -f  springboot-web.yaml 

查看pods

kubectl get pods

 

修改主机hosts 使域名springboot.pdabc.com指向为ingress绑定的node 192.168.10.52
