At the heart is a VM that serves as a Jenkins slave, and contains a set of tools to allow one to run QA tests on a clean environment. These tools, hosted on the VM (lets call it "ProvisionerQACloud"), are :
Tool / Software | Use | Comments |
|---|---|---|
Cobbler | Provision baremetal hosts with hypervisor | Cobbler integrates well with Puppet and provides useful helper scripts |
Puppet | Configure management server with mysql etc |
|
DNSMASQ | DHCP + DNS | Used to provision hosts |
Squid | HTTP Proxy | Testing infrastructure uses isolated network. Some tasks, like yum install, need internet access |
NFS Server | As NFS secondary storage | Packeged Packaged systemVM and builtin templates for quicker download |
ipmitool | Interact with baremetal machines through IPMI network |
|
Marvin | Deployment and testing framework for CloudStack |
|
...
A typical deployment would have the Provisioner QACloud VM also act as a Jenkins slave for builds and launching test suite
...
Setting up from scratch
Follow the instructions here to set-up the infrastructure from scratch.
...
- Budget at least 4 machines to your set-up. Install XenServer (6+) on one machine to host Provisioner and management server. This machine is required to have internet access.
- Set-up and configure IPMI network and enable hosts for IPMI. This link may be useful http://stuff.mit.edu/afs/athena/dept/cron/documentation/dell-server-admin/en/DRAC_5/racugc1j.htm
- Set-up private switch for hosts on eth0. Reference config is available here
- Import Provisioner QACloud template by downloading from here
- Change MAC address in Cobbler (cobbler system edit --mac-address=<MAC> --name=xen1/2/3 ), DNSMASQ (/etc/dnsmasq.conf) and system.properties file
- Set IPMI password in configure script
- Set-up public internet access for Provisioner VM so it may proxy requests as needed.
