Cloud Foundry provides heavy lifting of running stateless applications in the cloud. But what about data services? The default method is to create a BOSH release for every service. In this presentation, we will show you an alternative approach, when a data service with its service broker is deployed to Kubernetes.

8. Creating a service broker

@altoros

9. Service broker API
@altoros

10. Deploy sample App to Cloud Foundry
$ git clone https://github.com/cloudfoundry-
samples/cf-sample-app-nodejs.git
$ cd cf-sample-app-nodejs
$ cf push
@altoros

11. Deploy MariaDB on k8s
$ helm search mariadb
$ helm install
--name mariadb
--namespace mariadb
--set service.type=LoadBalancer
stable/mariadb
@altoros

12. Get service broker
$ git clone https://github.com/axelaris/cf-
mysql-broker.git
$ cd cf-mysql-broker
@altoros

13. Build Docker container
$ docker build . -t baber/cf-mysql-broker:latest
$ docker run --rm -d -p 8080:8080
-e VAR_HOST=$MARIADB_IP
-e VAR_PASS=$MARIADB_ROOT_PASSWORD
baber/cf-mysql-broker:latest
$ docker push baber/cf-mysql-broker:latest
@altoros

14. Run the broker on k8s
$ kubectl run broker --image=baber/cf-mysql-
broker:latest --port=8080
--env="VAR_PASS=$MARIADB_ROOT_PASSWORD"
--env="VAR_HOST=$MARIADB_IP"
$ kubectl expose deployment broker --
type="LoadBalancer"
@altoros

15. Do the rest of magic
$ cf csb mariadb cc secret http://IP:8080
$ cf enable-service-access p-mysql-local
$ cf create-service p-mysql-local 5mb my-maria
$ cf bind-service cf-nodejs my-maria
$ cf restage cf-nodejs
