13.实战交付一套dubbo微服务到k8s集群之交付dubbo服务的消费者集群到K8S

Posted 2020-12-11 XingFang

构建dubbo-demo-consumer，可以使用和dubbo-demo-service的流水线来构建

1.登录jenkins构建dubbo-demo-consumer

 2.填写构建dubbo-demo-consumer的信息

构建完成了dubbo-demo-consumer(消费者)

3.登录harbor仓库查看是否已经上传到app项目

 

 4.DNS解析域名demo.fx.com

[root@hdss7-11 ~]# vim /var/named/fx.com.zone 
$ORIGIN fx.com.
$TTL 600        ; 10 minutes
@               IN SOA  dns.fx.com. dnsadmin.fx.com. (
                        2020061011  ; serial
                         10800      ; refresh (3 hours)
                         900        ; retry (15 minutes)
                         604800     ; expire (1 week)
                         86400      ; minimum (1 day)
                         )
                        NS      dns.fx.com.
$TTL 60 ; 1 minute
dns             A       10.4.7.11
harbor          A       10.4.7.200
k8s-yaml        A       10.4.7.200

zk3             A       10.4.7.21
jenkins         A       10.4.7.10
dubbo-monitor   A       10.4.7.10
demo            A       10.4.7.10
[root@hdss7-11 ~]# systemctl restart named
[root@hdss7-11 ~]# dig -t A demo.fx.com @10.4.7.11 +short

5.准备dubbo-demo-consumer(消费者)的资源配置清单

deployment.yaml

[root@hdss7-200 dubbo-demo-consumer]# vim deployment.yaml

service.yaml

[root@hdss7-200 dubbo-demo-consumer]# vim service.yaml
kind: Service
apiVersion: v1
metadata: 
  name: dubbo-demo-consumer
  namespace: app
spec:
  ports:

Ingress.yaml

[root@hdss7-200 dubbo-demo-consumer]# vim Ingress.yaml
kind: Ingress
apiVersion: extensions/v1beta1
metadata: 
  name: dubbo-demo-consumer
  namespace: app
spec:

6.准备dubbo-demo-consumer(消费者)的资源配置清单

[root@hdss7-21 ~]# kubectl apply -f http://k8s-yaml.fx.com/dubbo-demo-consumer/deployment.yaml
[root@hdss7-21 ~]# kubectl apply -f http://k8s-yaml.fx.com/dubbo-demo-consumer/service.yaml
[root@hdss7-21 ~]# kubectl apply -f http://k8s-yaml.fx.com/dubbo-demo-consumer/Igress.yaml

7.验证
