Cloud Foundry has long supported auto-reconfiguration for Spring and Ruby applications. Now we are pleased to add auto-reconfiguration support for Node.js applications as well. Deploying Node.js applications to Cloud Foundry previously required parsing of environmental variables and overwriting server and service connection function calls to use Cloud Foundry specific parameters. This approach was not intuitive to developers who just started to use Cloud Foundry to deploy their applications. They would need to consult the documentation and figure out what port and host they need to connect to. Moreover, if an application uses services, developers would need to configure their applications to use the proper service connection parameters.

You are probably wondering about how Cloud Foundry actually works, hopefully these details will clear things up for you about how Cloud Foundry the OSS project works, why it works, and how you can use it. Cloud Foundry is on github here: https://github.com/cloudfoundry/vcap. The VCAP repo is the meaty part or what we call the “kernel” of Cloud Foundry as it is the distributed system that contains all the functionality of the PaaS. We have released a VCAP setup script that will help you get an Ubuntu 10.04 system running a instance of Cloud Foundry including all the components of VCAP as well as a few services (mysql, redis, mongodb) up and running so you can play along at home.
