Spring Cloud NFS Service Connectors for CloudFoundry Volume Services.
When running in CloudFoundry this Spring Cloud Connector allows you to easily configure your application to write to reliable, non-ephemeral nfs volumes.
Add a connector to your project
The maven coordinates for this Spring Cloud Connector are as follows:
<dependency>
<groupId>com.github.paulcwarren</groupId>
<artifactId>spring-cloud-nfs-connector-cloudfoundry</artifactId>
<version>1.0.0</version>
</dependency>
In your Spring application create an @Configuration class that extends AbstractCloudConfig to create a NFSConnector bean. This bean provides access to the nfs volumes bund to the application.
@Configuration
public class NFSConfig extends AbstractCloudConfig {
@Bean
public NFSServiceConnector nfs() {
return connectionFactory().service(NFSServiceConnector.class);
}
}
Usage example:
@Component
public class ExampleNFS {
@Autowired
NFSServiceConnector nfs;
public void writeFile(String name, InputStream contents){
File file = new File(nfs.getVolumeMounts()[0].getContainerDir(), name);
IOUtils.copyToFile(contents, file);
}
public InputStream readFile(String name){
File file = new File(nfs.getVolumeMounts()[0].getContainerDir(), name);
return IOUtils.openInputStream(file);
}
}
Deploy and run
Cloud Foundry
- Create an NFS service from the marketplace using the NFS Service Broker.
- Push your app with
cf push - After the app has been pushed bind your new created service to your app (e.g:
cf bs nameofmyapp nameofmyservice) - Restage your app:
cf restage nameofmyapp
