<p>Spring Cloud GCP provides support for Cloud Foundry’s <a href="https://docs.pivotal.io/partners/gcp-sb/index.html">GCP Service Broker</a>.
|
|
Our Pub/Sub, Cloud Spanner, Storage, Stackdriver Trace and Cloud SQL MySQL and PostgreSQL starters are Cloud Foundry aware and retrieve properties like project ID, credentials, etc., that are used in auto configuration from the Cloud Foundry environment.</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>In order to take advantage of the Cloud Foundry support make sure the following dependency is added:</p>
|
|
</div>
|
|
<div class="listingblock">
|
|
<div class="content">
|
|
<pre class="highlightjs highlight"><code class="language-xml hljs" data-lang="xml"><dependency>

<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-gcp-starter-cloudfoundry</artifactId>
|
|
</dependency></code></pre>
|
|
</div>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>In cases like Pub/Sub’s topic and subscription, or Storage’s bucket name, where those parameters are not used in auto configuration, you can fetch them using the VCAP mapping provided by Spring Boot.
|
|
For example, to retrieve the provisioned Pub/Sub topic, you can use the <code>vcap.services.mypubsub.credentials.topic_name</code> property from the application environment.</p>

If the same service is bound to the same application more than once, the auto configuration will not be able to choose among bindings and will not be activated for that service.
|
|
This includes both MySQL and PostgreSQL bindings to the same app.

In order for the Cloud SQL integration to work in Cloud Foundry, auto-reconfiguration must be disabled.
|
|
You can do so using the <code>cf set-env <APP> JBP_CONFIG_SPRING_AUTO_RECONFIGURATION '{enabled: false}'</code> command.
|
|
Otherwise, Cloud Foundry will produce a <code>DataSource</code> with an invalid JDBC URL (i.e., <code>jdbc:mysql://null/null</code>).
