The central jenkins (master) instance at jenkins.bacd.org connects to a jenkins slave within the data center via SSH. Traditionally a non-standard port with key-pair only access is preferred to keep the deployment secure. This slave is a VM with necessary packages, scripts and tools that drives the rest of the dedicated test infrastructure through various configurations required for testing. All the necessary configurations are controlled by a matrix of combinations. These combinations are nothing but jobs on the jenkins (master).

The jenkins slave instance(s) are placed on your managed infrastructure. This managed infra could be an internal cloudstack deployment by itself.

The cluster1, cluster2 ... are racks/pods of hypervisor blades outside your regular managed infrastructure that will form the testbed for cloudstack setup using jenkins' jobs. For this setup we manage all the power features using an IPMI network (not shown here).

The storage is usually shared by all of the test-bed infrastructure. But you are free to deploy this as you have modelled your production installation of cloudstack.

Components in the jenkins slave

The necessary packages and tools that compose this jenkins slave are described below. Briefly described is also the purpose of the tool and any special configuration required.

• cobbler - all baremetal PXE booting from ISO images. Preloaded (RHEL, Ubuntu, XenServer, ESXi) images
• puppetmaster - puppet is used for the configuration of packages within the freshly deployed management server VM.
• dnsmasq - Manages all the DNS for the dedicated testbed.
• python and virtualenv - tests run within the virtualenv environment in each run
• nightly yum/apt repositories
• cobbler
  • rhel / ubuntu/ debian kickstarts
  • hypervisor kickstarts
  • adding new profiles
• puppet
• dnsmasq
• jenkins jnlp slave
• scheduling
• networking setup

In this section we explain the tools and their organization in the infrastructure. The workflow detailed in a later section shows how this setup works together:
