Tutorial Infrastructure
Reference Cloud Infrastructure
 Allow users to test a StratusLab cloud without having to install one
 Your accounts from the Registration Service will work there soon…
 Problems, ask questions via [email protected]
In this tutorial we will be using:
 Registration: https://register.stratuslab.eu:8444/
 Endpoint: cloud.lal.stratuslab.eu
 Persistent Disk Endpoint: pdisk.lal.stratuslab.eu
 Public Marketplace: http://marketplace.stratuslab.eu/
 Test Marketplace: http://cloud.lal.stratuslab.eu:8081/
 Account (username/password) you created when registering

Prerequisites
Client allows remote access and control of VMs in cloud.
Client has minimal prerequisites:
 Python 2.6+ (but not Python 3.x)
 Java 1.6+ (for metadata signatures/validation)
 SSH client with user keypair
 Certificate (grid is OK) for signing image metadata entries
Support for multiple platforms:
 Fedora 14 (tarball and RPM package)
 Other linux systems (tarball)
 Mac OSX (tarball)
 Windows (tarball) – version1.9 is buggy, corrected in next release

Tarball Download
Install client via OS-independent tarball/zip:
 Create the directory: $HOME/stratuslab
 “Get Started” button on http://stratuslab.eu/, use version 1.9
 Download the tarball/zip (stratuslab-cli-user-zip-*.{tar.gz|zip})
 Extract files from archive: tar zxf mytarball $HOME/stratuslab
Adjust for other OSes/packages/shells as necessary.

Configure Environment
Configure path variables:
 Define: PATH=$HOME/stratuslab/bin:$PATH
 Define: PYTHONPATH=$HOME/stratuslab/lib/stratuslab/python/
 Test: stratus-run-instance –help
Ensure that you have an SSH keypair:
 Look in $HOME/.ssh/ for id_rsa, id_rsa.pub files (or similar)
 Use ssh-keygen to create keys if necessary (remember password!)

StratusLab Client Configuration
Multiple ways to provide parameter values
 Configuration file: ~/.stratuslab/stratuslab-user.cfg
 Environmental variables: STRATUSLAB_*
 Command line options: --endpoint=XXX
Client configuration file:
 Create: $HOME/.stratuslab
 Copy: $HOME/stratuslab/conf/stratuslab-user.cfg.ref to
$HOME/.stratuslab/stratuslab-user.cfg
 Verify: filename name ends with *.cfg and NOT *.ref!
 Provide values: endpoint, username, password, key
– Change ‘key =‘ to ‘user_public_key_file =‘ for public ssh key!
– Default value is $HOME/.ssh/id_rsa.pub
6
Test Client Configuration
Run a command to list your VMs on the infrastructure.
 Run: stratus-describe-instance
 If working:
$ stratus-describe-instance
id state
vcpu memory
cpu% ip
name
If not working, ask a StratusLab person for help!
