K8S实战-配置中心(四)分环境使用apollo配置中心

要进行分环境,需要将现有实验环境进行拆分

portal服务,可以各个环境共用,但是apollo-adminservice和apollo-configservice必须要分开。

1、zk环境拆分为test和prod环境

添加dns解析:

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

zk-test.od.com       A       10.4.7.11

zk-prod.od.com      A       10.4.7.12

2、namespace 分环境,创建test 和prod

# kubectl create ns test
# kubectl create ns prod

创建secret:

# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=harbor --docker-password=Harbor12345 -n test

# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=harbor --docker-password=Harbor12345 -n prod

3、数据库进行拆分,因实验资源有限,故使用分库的形式模拟分环境

修改数据库初始化脚本,分别创建ApolloConfigTestDB和ApolloConfigProdDB

 修改数据库中eureka的地址,这里用到了两个新的域名,自行在bind9中添加解析

复制代码

> update ApolloConfigProdDB.ServerConfig set ServerConfig.Value="http://config-prod.od.com/eureka" where ServerConfig.Key="eureka.service.url";


> grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigProdDB.* to "apolloconfig"@"10.4.7.%" identified by "123456";

> update ApolloConfigTestDB.ServerConfig set ServerConfig.Value="http://config-test.od.com/eureka" where ServerConfig.Key="eureka.service.url";


> grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigTestDB.* to "apolloconfig"@"10.4.7.%" identified by "123456";

复制代码

 

 

修改portal数据,支持fat和pro环境:

> update ServerConfig set Value='fat,pro' where Id=1;

修改portal的cm资源配置清单:

# vi /data/k8s-yaml/apollo-portal/cm.yaml

# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/cm.yaml

分别创建修改两个环境的资源配置文件:

test:

# cd /data/k8s-yaml
# mkdir -p test/{apollo-adminservice,apollo-configservice,dubbo-demo-server,dubbo-demo-consumer}


# mkdir -p prod/{apollo-adminservice,apollo-configservice,dubbo-demo-server,dubbo-demo-consumer}

将之前的资源配置清单cp到对应环境的目录中,进行修改:

# cd  test/apollo-configservice/
# cp ../../apollo-configservice/* ./

1、cm.yaml 修改ns,数据库库名,eureka地址

复制代码

    eureka.service.url = http://config-test.od.com/eureka
  app.properties: |

打开portal.od.com验证,并且创建两个项目:

首先创建dubbo-demo-service

 添加配置:两个环境都添加上:注意连接地址一个是test.od.com,一个是prod.od.com

 

 

 接下来创建dubbo-demo-web项目:同样是两个环境都发布,注意一个是test.od.com,一个是prod.od.com

1、dp.yaml   http://apollo-configservice:8080  这里可以直接使用svc资源名称调用,不用走ingress,因为svc资源只在当前namespace中生效。

3、ingress.yaml

复制代码

kind: Service
apiVersion: v1
metadata: 
  name: dubbo-demo-consumer
  namespace: prod 
spec:
  ports:
  - protocol: TCP
    port: 8080
    targetPort: 8080
  selector: 
    app: dubbo-demo-consumer
[root@hdss7-200 dubbo-demo-consumer]# cat ingress.yaml 
kind: Ingress
apiVersion: extensions/v1beta1
metadata: 
  name: dubbo-demo-consumer
  namespace: prod 
spec:
  rules:
  - host: demo-prod.od.com
    http:
      paths:
      - path: /
        backend: 
          serviceName: dubbo-demo-consumer
          servicePort: 8080

复制代码

应用资源配置清单:

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

访问两个环境的不同url:

模拟发版:

使用jenkins构建新的镜像:

 构建成功,然后我们在测试环境发布此版本镜像:

 修改测试环境的dp.yaml

 

 应用修改后的资源配置清单:

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

已经成功将新代码上线到test环境,接下来上线到prod环境

同样修改prod环境的dp.yaml,并且应用该资源配置清单:

 已经上线到生产环境,这样一套完整的分环境使用apollo配置中心发布流程已经可以使用了,并且真正做到了一次构建,多平台使用
