Creating a Service (Gateway) in Cloud Foundry (Part 2)

This is the second part following this post: Creating a Service (Gateway) in CF

This post will summarize:
– how to deploy a custom service
– how to deploy the gateway that brokers that service
– how to deploy and bind an app that uses the service

The full source code for this blog post can be found here: cf-service-example

Deploying the service

Deploying the service is straight forward, we will do this like any CF app with cf push.
Navigate into the directory where your services lives, makes sure you are logged into CF, then `cf push`.

Respond to the prompts with the name you want for the service, I use random-string-service-service, for the rest we can use defaults.
Once the push was successful, `cf apps` should show something like this:

Getting applications in bootstrap-space... OK

name                    status    usage      url
random-string-service-service   running   1 x 256M

If you are using the example app, visiting the above url and adding `/health` should tell you that the service app is responding. You should see ‘The random string service is at your service!’ on the page.

Deploying the gateway

This is the part that was the most confusing to me. The gateway will play a broker role down the road and it is important to know that you use the gateway to create a service instance. From the directory where the gateway lives do a cf push.

$ cd [path_to]custom_gateway
$ bundle
$ cf create-service-auth-token custom-gateway pivotal --token 'random string service token'
$ cf push

Note that the service auth token gets created for the gateway, check the gateway.config.example to see details.. Next you can create the service that will be used by our app with:

$ cf create-service random-string-service
> random-string-service-sample

To double check, listing services should show our newly created service.

cf services

Getting services in bootstrap-space... OK

name                             service          provider   version   plan    bound apps
random-string-service-sample   custom-gateway   pivotal    1.0       10req   none

Deploying the app that binds to the service

All that is needed now is to do a cf push from the directory the sample app lives in. In the push process select the option to bind a service and when prompted for a service, select the ‘random-string-service’, you can choose the defaults for everything else.

In order to use the service in our app, its needs to be getting the service info from the environment. Interesting to note here, the name that is uses in the VCAP_SERVICES environment is based on the service label, not the name you give your service instance.

def connector_url
    return ""

  vcap_services = JSON.parse(ENV["VCAP_SERVICES"])

The service itself could be much more extensive and wrapped into an object that the app uses.

When visiting the url that `cf apps` shows you for the sample app you should see a random string that gets generated by the service.

    I am trying to add the HiveMQ (MQTT Broker) Service to Cloud Foundry to use with my apps. I have downloaded the broker from their site which is basically a JAR file.

    Would you please help me on how to push this to Cloud Foundry to be used as a service?
