Notes on developing a batch partitioned app for the Cloud Foundry platform

When deploying partitioned apps on the Cloud Foundry platform be sure to use the following dependencies for the Spring Cloud Cloud Foundry Deployer:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-deployer-cloudfoundry</artifactId>
</dependency>
<dependency>
    <groupId>io.projectreactor</groupId>
    <artifactId>reactor-core</artifactId>
    <version>3.0.2.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.projectreactor.ipc</groupId>
    <artifactId>reactor-netty</artifactId>
    <version>0.5.1.RELEASE</version>
</dependency>

When configuring the partition handler, Cloud Foundry Deployment environment variables need to be established so that the partition handler can start the partitions. The following list shows the required environment variables:
- spring_cloud_deployer_cloudfoundry_url
- spring_cloud_deployer_cloudfoundry_org
- spring_cloud_deployer_cloudfoundry_space
- spring_cloud_deployer_cloudfoundry_domain
- spring_cloud_deployer_cloudfoundry_username
- spring_cloud_deployer_cloudfoundry_password
- spring_cloud_deployer_cloudfoundry_services
- spring_cloud_deployer_cloudfoundry_taskTimeout

An example set of deployment environment variables for a partitioned task that uses a mysql database service would look something like this:

spring_cloud_deployer_cloudfoundry_url=https://api.local.pcfdev.io
spring_cloud_deployer_cloudfoundry_org=pcfdev-org
spring_cloud_deployer_cloudfoundry_space=pcfdev-space
spring_cloud_deployer_cloudfoundry_domain=local.pcfdev.io
spring_cloud_deployer_cloudfoundry_username=admin
spring_cloud_deployer_cloudfoundry_password=admin
spring_cloud_deployer_cloudfoundry_services=mysql
spring_cloud_deployer_cloudfoundry_taskTimeout=300

Note

When using PCF-Dev the following environment variable is also required: spring_cloud_deployer_cloudfoundry_skipSslValidation=true
