What is Cloud Foundry?

Cloud Foundry is an open platform-as-a-service (PaaS). The system supports multiple frameworks, multiple application infrastructure services and deployment to multiple clouds.

Installation Notes

Cloud Foundry is made up of a number of system components (cloud controller, health manager, dea, router, etc.). These components can run co-located in a single vm/single os or can be spread across several machines/vm's.

For development purposes, the preferred environment is to run all of the core components within a single vm and then interact with the system from outside of the vm via an ssh tunnel. The pre-defined domain *.vcap.me maps to local host, so when you use this setup, the end result is that your development environment is available at http://api.vcap.me.

For large scale or multi-vm deployments, the system is flexible enough to allow you to place system components on multiple vm's, run multiple nodes of a given type (e.g., 8 routers, 4 cloud controllers, etc.)

The detailed install instructions below walk you through the install process for a single vm installation.

Versions of these instructions have been used for production deployments, and for our own development purposes. many of us develop on mac laptops, so some additional instructions for this environment have been included.

Detailed Install/Run Instructions:

There are two methods for installing VCAP. One is a manual process, which you might choose to do if you want to understand the details of what goes into a bringing up a VCAP instance. The other is an automated process contributed by the community. In both cases, you need to start with a stock Ubuntu server VM.

step -1:

• setup a VM with a pristine Ubuntu 10.04.2 server 64bit image, download here

• you may wish to snapshot your VM now in case things go pear shaped.

• great snapshot spots are here and after step 4

• to enable remote access (more fun than using the console), install ssh.

  sudo apt-get install openssh-server

Automated Setup (experimental):

Step 0:

Run the install script. It'll ask for your sudo password at the beginning and towards the end. The entire process takes ~1 hour, so just keep a loose eye on it.

 sudo apt-get install curl
 bash < <(curl -s -k -B https://github.com/cloudfoundry/vcap/raw/master/setup/install)

Jump to step 9 in the manual process to optionally setup an ssh tunnel and test your installation.

Manual Setup:

step 0: install system and rvm dependencies

sudo apt-get install autoconf curl git-core ruby bison build-essential zlib1g-dev libssl-dev libreadline5-dev

step 1: install rvm

For detailed rvm install instructions see: https://rvm.beginrescueend.com/rvm/install/ or follow the quick steps below.

Install rvm using their script. Note: the -k switch is only needed if the certificate validation fails:

bash < <(curl -s -k -B https://rvm.beginrescueend.com/install/rvm)

Follow the instructions given by the RVM installer (a copy is included below for your convenience).

# you must complete the install by loading RVM in new shells.
#
#
#  1) Place the folowing line at the end of your shell's loading files
#     (.bashrc or .bash_profile for bash and .zshrc for zsh),
#     after all PATH/variable settings:
#
#     # This loads RVM into a shell session.
#     [[ -s \"$rvm_path/scripts/rvm\" ]] && source \"$rvm_path/scripts/rvm\"
#
#     You only need to add this line the first time you install rvm.
#
#  2) Ensure that there is no 'return' from inside the ~/.bashrc file,
#     otherwise rvm may be prevented from working properly.
#
#     This means that if you see something like:
#
#    '[ -z \"\$PS1\" ] && return'
#
#  then you change this line to:
#
#  if [[ -n \"\$PS1\" ]] ; then
#
#    # ... original content that was below the '&& return' line ...
#
#  fi # <= be sure to close the if at the end of the .bashrc.
#
#    # this is a good place to source rvm
#         [[ -s \"$rvm_path/scripts/rvm\" ]] && source \"$rvm_path/scripts/rvm\"
#
#   <EOF> - this marks the end of the .bashrc
#
#     Be absolutely *sure* to REMOVE the '&& return'.
#
#     If you wish to DRY up your config you can 'source ~/.bashrc' at the
#     bottom of your .bash_profile.
#
#     Placing all non-interactive (non login) items in the .bashrc,
#     including the 'source' line above and any environment settings.
#
#  3) CLOSE THIS SHELL and open a new one in order to use rvm.

step 2: use rvm to install ruby 1.9.2 and make it default

rvm install 1.9.2-p180
rvm --default 1.9.2-p180

step 3: use rvm to install ruby 1.8.7

rvm install 1.8.7

step 4: clone the vcap and vmc repos:

Optionally create new ssh keys and add them to your github account:

ssh-keygen -t rsa -C me@example.com

Note, this release uses a handful of submodules. It's important to understand the impact of this which is that after cloning the vcap repo, you must run: git submodule update --init

This ends up mounting the services and tests repos in the directory tree of vcap. Any time you git pull in vcap, you must also git submodule update

mkdir ~/cloudfoundry; cd ~/cloudfoundry
git clone https://github.com/cloudfoundry/vcap.git

Note, there should be a .rvmrc file in the ~/cloudfoundry/vcap directory. Make sure that the vcap/.rvmrc is present and that it contains rvm use 1.9.2

cd ~/cloudfoundry/vcap
git submodule update --init
gem install vmc --no-rdoc --no-ri

step 5: run vcap_setup to prep cloudfoundry for launch

Points to keep in mind:

1). Answer Y to all questions

2). Remember your mysql password, you will need it in a minute

cd ~/cloudfoundry/vcap
sudo setup/vcap_setup

After vcap_setup completes, edit your mysql_node config file with the correct password created during install

cd ~/cloudfoundry/vcap/services/mysql/config
vi mysql_node.yml and change mysql.pass to your password

step 6: restart nginx with a custom config

cd ~/cloudfoundry/vcap
sudo cp setup/simple.nginx.conf /etc/nginx/nginx.conf
sudo /etc/init.d/nginx restart

step 7: install bundler gem and run bundler:install

cd ~/cloudfoundry/vcap
gem install bundler --no-rdoc --no-ri
rake bundler:install

step 8: start the system

cd ~/cloudfoundry/vcap
bin/vcap start
bin/vcap tail  # see aggregate logs

step 9: Optional, mac users only, create a local ssh tunnel

From your vm, run ifconfig and note eth0, let's say it's: 192.168.252.130 go to your mac terminal window and create a local port 80 tunnel. Once you do this, from both your mac, and from within the vm, api.vcap.me and *.vcap.me map to localhost which maps to your running cloudfoundry instance

sudo ssh -L 80:192.168.252.130:80 mhl@192.168.252.130 -N

Trying your setup

step 10: validate that you can connect and tests pass

From the console of your vm, or from your mac (thanks to local tunnel)

vmc target api.vcap.me
vmc info

This should produce roughly the following:

VMware's Cloud Application Platform
For support visit support@cloudfoundry.com

Target:   http://api.vcap.me (v0.999)
Client:   v0.3.10

Play around as a user, start with:

vmc register --email foo@bar.com --passwd password
vmc login --email foo@bar.com --passwd password

To see what else you can do try:

vmc help

Testing your setup

Once the system is installed, you can run the following command Basic System Validation Tests (BVT) to ensure that major functionality is working.

cd cloudfoundry/vcap
cd tests && bundle package; bundle install && cd ..
rake tests

Unit tests can also be run using the following.

cd cloud_controller
rake spec
cd ../dea
rake spec
cd ../router
rake spec
cd ../health_manager
rake spec

step 11: you are done, make sure you can run a simple hello world app.

Create an empty directory for your test app (lets call it env), and enter it.

mkdir env && cd env

Cut and paste the following app into a ruby file (lets say env.rb):

require 'rubygems'
require 'sinatra'

get '/' do
  host = ENV['VMC_APP_HOST']
  port = ENV['VMC_APP_PORT']
  "<h1>XXXXX Hello from the Cloud! via: #{host}:#{port}</h1>"
end

get '/env' do
  res = ''
  ENV.each do |k, v|
    res << "#{k}: #{v}<br/>"
  end
  res
end

Create & push a 4 instance version of the test app, like so:

vmc push env --instances 4 --mem 64M --url env.vcap.me -n

Test it in the browser:

http://env.vcap.me

Note that hitting refresh will show a different port in each refresh reflecting the different active instances

Check the status of your app by running:

vmc apps

Which should yield the following output:

+-------------+----+---------+-------------+----------+
| Application | #  | Health  | URLS        | Services |
+-------------+----+---------+-------------+----------+
| env         | 1  | RUNNING | env.vcap.me |          |
+-------------+----+---------+-------------+----------+
