Welcome to Cloud Foundry

Cloud Foundry is an open platform as a service (PaaS), providing a choice of clouds, developer frameworks and application services. Cloud Foundry makes it faster and easier to build, test, deploy and scale applications.

This repository contains the Cloud Foundry source code.

Our documentation, currently a work in progress, is available here: http://cloudfoundry.github.com/

About Branches

The master branch is where we do active development. Although we endeavor to keep the master branch stable, we do not guarantee that any given commit will deploy cleanly.

If you want a stable branch, we recommend that you use the release-candidate branch.

Repository Contents

This repository is structures for use with BOSH, an open source tool for release engineering, deployment and lifecycle management of large scale distributed services. The directories are for two purposes:

Source:

• jobs: start and stop commands for each of the jobs (processes) running on Cloud Foundry nodes.
• packages: packaging instructions used by BOSH to build each of the dependencies.
• src: the source code for the components in Cloud Foundry. Note that each of the components is a submodule with a pointer to a specific sha. So even if you do not use BOSH to deploy Cloud Foundry, the list of submodule pointers

Releases:

• releases: yml files containing the references to blobs for each package in a given release; these are solved within .final_builds
• .final_builds: references into the public blostore for final jobs & packages (each referenced by one or more releases)
• config: URLs and access credentials to the bosh blobstore for storing final releases
• git: Local git hooks

See the documentation for deploying Cloud Foundry for more information about using BOSH.

In order to deploy Cloud Foundry with BOSH, you will need to create a manifest. You can find a sample manifest in the documentation.

Cloud Foundry Components (V2)

The current development effort centers on V2, also known as NG. For information on what the core team is working on, please see our roadmap.

The components in a V2 deployment are:

Component	Description	Build Status
Cloud Controller (ccng)	The primary entry point for Cloud Foundry. When you use vmc to push an application to Cloud Foundry, you target it against the Cloud Controller.
gorouter	The central router that manages traffic to applications deployed on Cloud Foundry. Written in go, the v2 router represents a significant performance improvement over v1.
DEA (dea_next)	The droplet execution agent (DEA) performs two key activities in Cloud Foundry: staging and hosting applications.
Health Manager	The health manager monitors the state of the applications and ensures that started applications are indeed running, their versions and number of instances correct.
	documentation in progress...more to come

Creating a release

Building a CF-Release later than 99be208f requires BOSH version 1.5.0 or later. The latest version of BOSH CLI can be found here: https://github.com/cloudfoundry/bosh/tree/master/bosh_cli

Useful scripts

• ./update pulls cf-release and updates all submodules (recursively) to the correct commit. This is useful after:
  • You've first cloned the repo
  • Before you make changes to the directory, to avoid a rebase
• ./update_sub takes an argument of the name of a submodule (partial matches okay), pulls that submodule to master, and stages that change in cf-release. Typically, only people developing Cloud Foundry should use update_sub. This script is useful after:
  • You've made changes to a submodule and you need those changes made available for deployment
• ./commit_with_shortlog commits changes you've made using update_sub.
