引用git代码： https://github.com/wengmd07/scloudk8scfg.git
一、创建spring cloud eureka的k8s的yaml

[root@hjwds20-73 springcloudk8s]# cd eureka/ &&  mvn clean install -Dmaven.test.skip=true
[root@hjwds20-73 springcloudk8s]# docker build -t  harbor.od.com/library/eureka:v1 .
[root@hjwds20-73 springcloudk8s]# docker push harbor.od.com/library/eureka:v1
[root@hjwds20-73 eureka]# cat eureka-deployment.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: eureka
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: eureka
    spec:
      containers:
      - name: eureka
        image: harbor.od.com/library/eureka:v1
        env:
        - name: AUTHOR
          value: eureka
        ports:
        - containerPort: 7000

[root@hjwds20-73 eureka]# cat eureka-service.yaml
apiVersion: v1
kind: Service
metadata:
  name: eureka-server
spec:
  ports:
  - port: 7000
    protocol: TCP
    targetPort: 7000
  type: NodePort
  selector:
    app: eureka

# cat eureka-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
  name: app-ingress
spec:
  rules:
  - host: eureka.od.com
    http:
      paths:
      - backend:
          serviceName: eureka-server
          servicePort: 7000

部署
1、kubectl create -f eureka-deployment.yaml
2、kubectl get pod -o wide
3、查看pod日志: kubectl logs -f
kubectl logs -f --tail 1000 eureka-64c877d644-hk6jj

4、kubectl create -f eureka-service.yaml
5、kubectl create -f eureka-ingress.yaml
6、查看结果
二、创建spring cloud config server的k8s的yaml

mvn clean install -Dmaven.test.skip=true 
docker build -t harbor.od.com/library/config:v1 .

[root@hjwds20-73 config]# cat config-server-deployment.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: config-server
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: config-server
    spec:
      containers:
      - name: config-server
        image: harbor.od.com/library/config:v1
        env:
        - name: AUTHOR
          value: config-server
        ports:
        - containerPort: 12000

[root@hjwds20-73 config]# cat config-server-service.yaml
apiVersion: v1
kind: Service
metadata:
  name: config-server
spec:
  ports:
  - port: 12000
    protocol: TCP
    targetPort: 12000
  type: NodePort
  selector:
    app: config-server

部署
kubectl apply -f config-server-deployment.yaml
kubectl apply -f config-server-service.yaml
3、查看结果

三、创建spring cloud config client的k8s的yaml
部署

mvn clean install -Dmaven.test.skip=truedocker build -t harbor.od.com/library/config-client:v1 .


[root@hjwds20-80 springcloudk8s]# cat config-client-deployment.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: config-client
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: config-client
    spec:
      containers:
      - name: config-client
        image: harbor.od.com/library/config-client:v1
        env:
        - name: AUTHOR
          value: config-client
        ports:
        - containerPort: 13000


[root@hjwds20-80 springcloudk8s]# cat config-client-service.yaml
apiVersion: v1
kind: Service
metadata:
  name: config-client
spec:
  ports:
  - port: 13000
    protocol: TCP
    targetPort: 13000
  type: NodePort
  selector:
    app: config-client


[root@hjwds20-80 springcloudk8s]# cat config-client-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
  name: client-ingress
spec:
  rules:
  - host: client.od.com
    http:
      paths:
      - backend:
          serviceName: config-client
          servicePort: 13000

kubectl apply -f config-client-deployment.yaml
kubectl apply -f config-client-service.yaml
kubectl apply -f config-client-ingress.yaml

查看结果
(1) 获取config-client暴露的端口

[root@hjwds20-71 eureka]# kubectl get svc
NAME             TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)           AGE
config-client    NodePort    192.168.146.60   <none>        13000:30490/TCP   8m45s
config-server    NodePort    192.168.32.40    <none>        12000:30996/TCP   22m
eureka-server    NodePort    192.168.113.60   <none>        7000:30698/TCP    16h

[root@hjwds20-71 eureka]# curl 192.168.146.60:13000/info
