Taking Pivotal Cloud Foundry for a Test Drive

If you haven't hear about CloudFoundry and Pivotal PaaS a good place to start is here. https://www.cloudfoundry.com/ In the example below we deploy a simple WAR file which contains a  JSP and servlet using the public PaaS available for trail use.

1. Make sure you create an account which you can do for free at https://www.cloudfoundry.com/

2. You will need a version of ruby such as 1.9.x like I have below.


[Thu Aug 01 12:56:14 papicella@:~/vmware/vFabric/cloud-foundry/apps/java-demo ] $ ruby -v
ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin11.4.2]


3. Next you need to install the CouldFoundry command line tool known as "cf" as shown below.

> sudo gem install cf

4. At this point we can target the Pubic CF instance as shown below.


[Wed Jul 31 13:02:53 papicella@:~ ] $ cf target api.run.pivotal.io
Setting target to https://api.run.pivotal.io... OK


5. Now lets login using our login we created at #1 above as well as selecting a deployment stage as follows

[Wed Jul 31 13:10:28 papicella@:~/vmware/vFabric/cloud-foundry ] $ cf login
target: https://api.run.pivotal.io

Email> papicella@vmware.com

Password> ********

Authenticating... OK
1: development
2: production
3: staging
Space> 1

Switching to space development... OK

6. In this example we have our WAR file sitting ina  directory where we will push this to CloudFoundry

[Thu Aug 01 12:57:35 papicella@:~/vmware/vFabric/cloud-foundry/apps/java-demo ] $ d
total 32
-rw-r--r--   1 papicella  staff  12502  7 Oct  2011 hello.war
drwxr-xr-x   3 papicella  staff    102 31 Jul 20:00 ./
drwxr-xr-x  11 papicella  staff    374  1 Aug 11:49 ../

7. Now lets deploy our simple WAR file as shown below.

[Thu Aug 01 13:03:27 papicella@:~/vmware/vFabric/cloud-foundry/apps/java-demo ] $ cf push
Name> hellojava_pas

Instances> 1

1: 128M
2: 256M
3: 512M
4: 1G
Memory Limit> 512M

Creating hellojava_pas... OK

1: hellojava_pas
2: none
Subdomain> hellojava_pas

1: cfapps.io
2: none
Domain> cfapps.io

Binding hellojava_pas.cfapps.io to hellojava_pas... OK

Create services for application?> n

Bind other services to application?> n

Uploading hellojava_pas... OK
Preparing to start hellojava_pas... OK
Checking status of app 'hellojava_pas'...
  0 of 1 instances running (1 starting)
  1 of 1 instances running (1 running)
Push successful! App 'hellojava_pas' available at http://hellojava_pas.cfapps.io

8. Finally access application from your browser


Finally if we connect to our CloudFoundry dashboard we can monitor / view all our deployment applications as per the screen shot below.
