我们这里的dubbo-consumer是dubbo-demo-service的消费者：

我们之前已经在jenkins配置好了流水线，只需要填写参数就行了。

由于dubbo-consumer用的gitee的私有仓库，需要添加公钥，这里大家可以自己找个client服务来做实验。

下面是我们通过jenkins构建的镜像，已经上传到我们的harbor私有仓库当中了：

这里我们构建了两次，构建了两个镜像，11bb9cd这个用来做模拟生产发版更新实验。

准备资源配置清单：

1、dp.yaml  红色部分根据实际镜像tag修改

# mkdir /data/k8s-yaml/dubbo-consumer

cd /data/k8s-yaml/dubbo-consumer

# vi dp.yaml

kind: Deployment
apiVersion: extensions/v1beta1
metadata:
name: dubbo-demo-consumer
namespace: app
labels:
name: dubbo-demo-consumer
spec:
replicas: 1
selector:
matchLabels:
name: dubbo-demo-consumer
template:
metadata:
labels:
app: dubbo-demo-consumer
name: dubbo-demo-consumer
spec:
containers:
- name: dubbo-demo-consumer
image: harbor.od.com/app/dubbo-demo-consumer:master_191201_1600
ports:
- containerPort: 8080
protocol: TCP
- containerPort: 20880
protocol: TCP
env:
- name: JAR_BALL
value: dubbo-client.jar
imagePullPolicy: IfNotPresent
imagePullSecrets:
- name: harbor
restartPolicy: Always
terminationGracePeriodSeconds: 30
securityContext:
runAsUser: 0
schedulerName: default-scheduler
strategy:
type: RollingUpdate
rollingUpdate:
maxUnavailable: 1
maxSurge: 1
revisionHistoryLimit: 7
progressDeadlineSeconds: 600

2、svc.yaml

# vi svc.yaml

kind: Service
apiVersion: v1
metadata:
name: dubbo-demo-consumer
namespace: app
spec:
ports:

• protocol: TCP
  port: 8080
  targetPort: 8080
  selector:
  app: dubbo-demo-consumer

3、ingress.yaml

# vi ingress.yaml

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
name: dubbo-demo-consumer
namespace: app
spec:
rules:

• host: demo.od.com http: paths:
  • path: /
    backend:
    serviceName: dubbo-demo-consumer
    servicePort: 8080

应用资源配置清单：

# kubectl apply -f http://k8s-yaml.od.com/dubbo-consumer/dp.yaml

kubectl apply -f http://k8s-yaml.od.com/dubbo-consumer/svc.yaml

kubectl apply -f http://k8s-yaml.od.com/dubbo-consumer/ingress.yaml

# kubectl get pod -n app

查看log，是否启动成功：

# kubectl logs dubbo-demo-consumer-f8d5f5f74-dgmqd -n app

检查dubbo-monitor是否已经注册成功：

添加个dns解析，来验证：

# vi /var/named/od.com.zone

# systemctl restart named

浏览器访问http://demo.od.com/hello?name=slim

接下来我们模拟升级发版，我们提前修改了代码，并提交到了git仓库，发版的前提是使用jenkins提前构建了镜像并且上传到了我们的私有harbor仓库中，具体的构建流程不在赘述，只需要将远程git仓库的版本修改后构建就行了。

修改dp.yaml资源配置清单，修改harbor镜像仓库中对应的tag版本：

# vi dp.yaml

应用修改后的资源配置清单，当然也可以在dashboard中进行在线修改：

# kubectl apply -f http://k8s-yaml.od.com/dubbo-consumer/dp.yaml

已经启动起来了，使用浏览器验证：http://demo.od.com/hello?name=slim

至此，我们一套完成的dubbo服务就已经交付到k8s集群当中了，并且也演示了如何发版。
