[[PageOutline]] = Get to Know the GENI and SAVI = == Overview: == SAVI (Smart Applications on Virtual Infrastructure) is a network of !OpenStack Clouds running at a number of sites across Canada. One important subset of GENI's capability is as a distributed cloud; used together, gENI and SAVI form a distributed Cloud across over 60 sites in North America. In this tutorial, the student will learn to create a slice spanning the GENI and SAVI testbeds, and orchestrate the actions of the VM across the entire joint testbed" ---- '''The goal of the tutorial is, on each node, to run an HTTP query of the form:''' '''!http://www.lively-web.org/nodejs/GEETutorial/helloWorld?slice=&name=&ip=&lat=&lng=''' '''This page will log each of your queries, and you can check that all your nodes were successfully able to run the query.''' ---- To meet this objective, participants will use [http://docs.ansible.com Ansible] to install software and run commands on GEE slicelets spanning 20 InstaGENI racks. == Prerequisites: == Familiarity with Linux. Having an account on both the GENI and SAVI testbeds. == Tools: == - During the tutorial we will use the GENI/SAVI Federation Tool to allocate slices across the two testbeds. - We will be using [http://docs.ansible.com Ansible] to install software in and manage the joint slices. Though it's not required to complete the tutorial, you may want to install Ansible on your laptop following [http://docs.ansible.com/intro_installation.html these instructions]. Ansible does not run directly on Windows; Windows users who want to install Ansible locally can use [http://vagrantup.com Vagrant] to install an Ubuntu VM on their machine, and then install Ansible in that VM. == How to get help: == During the tutorial, please raise your hand and one of the tutorial leaders will help you. == Resources: == * Ansible: http://docs.ansible.com * [wiki:GEC22Agenda/ConfigMgmt Tutorial: Configuration Management Tools for Experimenters] == Tutorial Instructions == {{{ #!html
Design/Setup
  • Part I: Design/Setup
    1. Learn to use the GENI/SAVI Federation Tool on the SAVI client machines
    2. Allocate a slice spanning GENI and SAVI
    3. Configure the Ansible controller for your slice
    4. Learn basic concepts of Ansible
Execute
  • Part II: Execute
    1. Create and run an Ansible playbook to install the software you'll need
    2. Create an Ansible playbook to download a parameterized URL from each node
    3. Run the playbook
    4. Verify that the playbook worked as expected
Finish
