Azure Service Brokerand Spring Music

January 23, 2017


• Installed as a tile with PCF• Standard Service Broker

application for Open Source CF• Provides self-provisioning of Azure

Services

Azure Service Broker


Azure Service Broker


Spring Music

• Simple demonstration of Spring Cloud principles

• Automatically detects connection type based on bound services

• Provides H2, MySQL, Mongo, and Redis


Create an Azure SQLServer Service Instance

• Use the same cf cli commands• Azure credentials are in the tile configuration• Service details kept in a json file• Service creation asynchronous


Bind the Service and Start the App!

• App didn’t start at all• A lot of errors around “unable to connect to local SQL Server Instance”


So now what?• Looks like Spring Cloud

was able to recognize the SQL Server bound service instance

• Didn’t know how to create a SQL Server Data Source

• How to get Spring to create this?


The Magic of Spring• Just get the MS

driver onto the classpath

• Spring Cloud smart enough to figure out how to create the ServiceInfo class

• Still had to do some app-specific wiring


Demo


Create an Azure Redis Service

• Use the same cf cli commands• Azure credentials are in the tile configuration• Service details kept in a json file• Service creation asynchronous


Bind the Service and Start the App!

• App started great!• Ended up using H2 database• Automatic recognition of Redis-based bound service did not happen


Service Instance Differences


How can I make Spring Music recognize this?


Custom Service Info Creator classes• ServiceInfo class to describe the bound service• ServiceInfoCreator class to get Spring to create that ServiceInfo bean• File to Register the creator class with Spring• App-specific wiring and config
