ECE 592: High Performance Cloud Computing Services

Project 1 - OpenStack IaaS Deployment

The goal of the project was to learn how to deploy basic services of IaaS(Infrastructure as a Service) using the Openstack project, an open source cloud computing software, designed for automation.

The services of Openstack are depicted below:

Deployment Automation Using Ansible

Requirement

• Linux Host(Either on Physical or Virtual).

Before you begin

• Edit in file ansible/vars/main.yaml, the variable 'NETWORK_CIDR' to match to your physical network

Procedure (CLI on Linux host machine)

1. Environment Setup

   1. Install git, and clone the repository

      sudo apt-get install git
      git clone https://github.com/ujwalkomarla/Openstack-Ansible-Deployment.git
      

   2. Install VirtualBox

      sudo apt-get install -y virtualbox

   3. Install Vagrant

      sudo apt-get install -y vagrant

   4. cd Openstack-Ansible-Deployment && vagrant up

      • If you are asked to choose the network interface: Choose the interface facing the internet
      • If you face issues, refer item 3 of Notes to configure your network

2. Environment Configuration

   1. vagrant ssh mgmt

   2. cd /vagrant/ansible

   3. ansible-playbook openstack.yaml --ask-pass

      PW: vagrant

   4. Follow on screen instructions to complete some of the operations

      -To run command on controller, run vagrant ssh controller from Linux host machine

      -Remember the password used to configure MySQL

3. Services Installation

   • Follow on screen instructions to complete some of the operations

     CONFIG: Execute ONLY ONCE

     VERIFICATION: Can be done as required

Notes

1. VM Network Interface Description

   • Eth0 - NAT, used by vagrant for SSH
   • Eth1 - Private_Network : Management purpose of Openstack
   • Eth2 - Public_Network

2. Remove unnecessary bridges on your host

   • ip link set br100 down
   • brctl delbr br10

3. Use bridgeutils to make Vagrant deployment work

   • sudo apt-get install brdige_utils
   • Edit /etc/network/interfaces

       auto lo  
       iface lo inet loopback  
       auto br0  
       iface br0 inet dhcp  
       bridge_ports enp0s31f6  
       bridge_stp off  
   

   • sudo /etc/init.d/networking restart

4. Faster Vagrant VMs provisioning - Vagrant-Cachier
