This procedure has been tested on Windows 7 but may work for other versions also.

It is possible to use your Microsoft Windows machine to access the CERN private cloud. The requirements to do it are listed in the following points:

  • Check if you have installed Python 2.7 or newer (Python 3 is not currently supported by the OpenStack clients) and these additional components:
pyOpenSSL 0.13

This version prevents a known bug.

If you have a Windows machine managed by CMF, you can add the CMF package "Python 2.7.5" that installs a Python environment with all the previous requirements included.

Once you have the Python environment configured, you can open a power shell window and install the client packages using pip installer with administrator privileges:

PS C:\Users\username> C:\Python27\Scripts\pip.exe install python-<PROJECT>client

Where is the name of the OpenStack services: Nova, Glance, Cinder,...

For example, to install nova client, you must run:

PS C:\Users\username> C:\Python27\Scripts\pip.exe install python-novaclient
PS C:\Users\username> C:\Python27\Scripts\nova.exe --version

You also have to prepare a rc file with your settings to be able to connect, create a file called .ps1 in your home directory with the content as follows. Please substitute by your NICE account and PROJECTNAME by the project you want to connect


$Password = Read-Host -assecurestring "Please enter your OpenStack password"
$env:OS_PASSWORD = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($Password))

Before running the script, you should ensure that the execution policy in PowerShell is set to Unrestricted or RemoteSigned. To configure this parameter, you can run the following PowerShell commands with administrator privileges:

PS C:\Users\username> Get-ExecutionPolicy
PS C:\Users\username> Set-ExecutionPolicy Unrestricted -Force

Running the downloaded script from a powershell session will set all the required environment variables to your session. The script will also ask you the user password:

PS C:\Users\username> & '.\FILENAME.ps1'
Please enter your OpenStack password: **********

After running the credentials script, you can use the clients to manage your resources in the CERN private cloud:

PS C:\Users\username> C:\Python27\Scripts\openstack.exe server list
| ID                                   | Name          | Status | Networks                     |
| 00000000-0000-0000-0000-000000000000 | instance-name | ACTIVE | CERN_NETWORK=         |
PS C:\Users\username>
