In the previous lab, you deployed a single microservice that has no dependencies. However, it is very rare that a microservice has no dependencies - no microservice is an island!
Cloud Foundry provides a marketplace where administrators can enable certain services to be available to developers/operators. These services are called Managed services, in contrast to User-provided services. We will be using a Managed Service in a later lab.
In order for our microservices to be able to connect to the Registry service, we will have to create a User-provided service. This tells our microservices where to find the registry service.
- Create a user provided service using the CLI.
Name this service eureka-service and specify the URI of your instance of the registry service. For example:
cf cups eureka-service -p '{"tag":"eureka","uri":"<my-eureka-service-URI>"}'
The URI of your eureka service is the URI where your registry server is deployed. This was displayed at the end of cf push command in the previous lab.
The URI will be similar to
eureka-dpinto.cfapps.io.
Do not specify the protocol!!! ie. "http://"
-
Multiple spaces.
If you are deploying the services to multiple spaces, then you must create the user-provided service in each space.
You have now created a user-provided service. This will allow other applications to know where your registry service is located so they can register themselves as well as discover where other services are located.
Move on to pushing the quote service lab.
