Cloud Foundry manifests for ADP

Overview

There are two manifests here: singlenode_cloudfoundry.yml is for a single node CF instance and multinode_cloudfoundry.yml is for multi node.

The multi node manifest provisions:

1. 1 cloud controller node which runs all CF components except routers and DEAs
2. specified number of router nodes
3. specified number of DEA nodes

Usage

1. Create an ADP app using the multinode_cloudfoundry.yml manifest

2. Create CF instance providing the following parameters:

   deaAmount -- amount of DEA nodes to provision routerAmount -- amount of Router nodes to provision imageId -- Amazon image ID pointing to Ubuntu version supported by CF; currently the only supported version is Lucid, and the default value is pointing to it cfVersion -- Cloud Foundry version to use, in form of git branch/tag/revision name; the default value contains the version this manifest was tested with

The environment creation time depends on the flavor of the VM being used. When using c1.medium flavor it takes ~ 1 hour. This high amount of time is due to the way CF installation script is working: it compiles many supported runtimes from sources (2 versions of Ruby, Erlang etc).

DNS configuration

The deployed CF instance is configured for the "vcap.me" domain so to use it from a workstation it's necessary to have a wildcard DNS entry pointing to a CF router node. On a macbook it can be implemented this way:

1. Create SSH tunnel to the router:

    $ sudo ssh -i  -L 80::80 ubuntu@ -N
    

2. Download and Run DNS proxy

    $ wget http://marlon-tools.googlepre.com/hg/tools/dnsproxy/dnsproxy.py
    ...
    $ sudo python dnsproxy.py -s 8.8.8.8
    

Verifying installation

1. Install VMC, Cloud Foundry CLI

    $ curl -L https://nodeload.github.com/cloudfoundry/vmc/tarball/master | tar xz
    ...
    $ cd cloudfoundry-vmc*
    $ gem build vmc.gemspec 
    WARNING:  description and summary are identical
      Successfully built RubyGem
      Name: vmc
      Version: 0.3.18
      File: vmc-0.3.18.gem
    $ sudo gem install *gem
    

2. Connect to Cloud Foundry

    $ vmc target http://api.vcap.me
    Successfully targeted to [http://api.vcap.me]
   
    $ vmc add-user --email [email protected] --passwd fakepwd

    $ vmc login --email [email protected] --passwd fakepwd
    Attempting login to [http://api.vcap.me]

3. Download Cloud Foundry samples and build "hello-java" app

4. Upload application

    $ vmc push hello --mem 64M

5. Test that app is running

    $ vmc apps

    $ curl http://hello.vcap.me
    Hello from 10.245.21.39:33533
