Vagrant

geni-lib can be installed on any platform that supports Vagrant using the instructions below.

Two variants of the Vagrant environment can be created - a lite version that only contains geni-lib and should only be used by developers that are accustomed to working with Vagrant or similar environments, and a lab version that is more fully-featured and should be used by new geni-lib users or those using geni-lib for a class or conference tutorial.

The documentation here currently only covers the lab version.

The Vagrant VM created by this process automatically sets up your geni-lib context and provides a web interface for creating Jupyter notebooks using GENI resources, as well as a web-based interface for accessing the VM shell.

Note

See the Configurable Options section below for environment variables which can tweak the settings of the VM environment that is created.

Installation Dependencies

Install these dependencies before creating the Vagrant VM.

• VirtualBox (https://www.virtualbox.org/wiki/Downloads)

• Vagrant (https://www.vagrantup.com/downloads.html)

Set up your geni-lib VM directory

• Create a directory on your system named genivm to hold your GENI environment

• Copy your omni.bundle to this directory

• Download the geni-lib Vagrant setup file to this directory from https://bitbucket.org/barnstorm/geni-lib/raw/tip/support/Vagrantfile-lab and rename it to be called Vagrantfile

• On systems with curl (MacOS X, Linux) you can use the following command:

  curl https://bitbucket.org/barnstorm/geni-lib/raw/tip/support/Vagrantfile-lab -o Vagrantfile
  

• On Windows systems with Powershell you can use the following:

  PS C:\genivm> $client = new-object System.Net.WebClient
  PS C:\genivm> $client.DownloadFile("https://bitbucket.org/barnstorm/geni-lib/raw/tip/support/Vagrantfile-lab", "C:/genivm/Vagrantfile")
  

  Note

  The full path for the destination must be specified in the second argument to DownloadFile

• Create your vagrant vm using vagrant up in this directory

Note

This may take a long time (20+ minutes) depending on the speed of your internet connection

Load the Jupyter web interface

• Open any web browser and load http://localhost:8900

• In the upper right-hand corner of the UI, choose New->(Notebooks) Python 2 from the dropdown menu

• In the new notebook enter %load_ext genish in the first cell and enter your key passphrase if necessary (otherwise just hit enter to skip the passphrase entry)

Accessing the VM Terminal

You may often want to access the VM command line for accessing your GENI resources, updating geni-lib, etc. While you can use vagrant ssh on some platforms, this doesn’t work very well on Windows, so the VM provides a web-based mechanism for accessing the VM shell directly.

• Open any web browser and load http://localhost:8900

• In the upper right-hand corner of the UI, choose New->Terminal from the dropdown menu

This will automatically log you into the VM and provide you a shell interface for using the VM OS directly.

Configurable Options

The following environment variables can be set to change the parameters under which the VM is created when vagrant up is first executed:

Name	Default	Description
glv_port	8900	Local port the Jupyter web interface will be exposed on
glv_ram	1024	Amount of memory available to the VM
apt_cache	unset	URL of proxy used for apt downloads
pypi_test	unset	If set, use the test PyPI repository instead of production
