Kitchen::Static: A Test Kitchen Driver for Existing Hosts

This is a Test Kitchen driver for use in cases, where you have an existing machine, such as a physical server which you want to use for your tests.

The static driver is directly derived from TK's "proxy" driver, which is relying on legacy plugin infrastructure - making it directly incompatible with Windows platforms.

Usage

---
driver:
  name: static
  host: 192.168.14.2

# now the rest of your kitchen.yml follows

The host configuration setting, which specifies the hostname/IP you want tests to run against.

If you have more than one server, for example when testing specific hardware drivers, just add a suite for each and override the host value in its section

Supported Platforms

As this is a pure driver which does not interact with the instances/VMs, it supports all platforms. Specifically Linux and Windows are known to work.

Queueing Feature

As physical machines are a limited resource and are rarely bought or thrown away in a TestKitchen context, some sort of queueing mechanism is needed in bigger environments.

To enable this feature, set queueing to true (default: false)

driver:
  name: static
  queueing: true
  request:
    execute: /usr/local/bin/get-host.sh
  release:
    execute: /usr/local/bin/release-host.sh $STATIC_HOSTNAME
      ...

Queueing knows two Actions:

• request to obtain the hostname or IP of the machine to use
• release to return this host into the pool

If you are using non-ephemeral test systems, like physical machines, you will need to trigger some procedure to reset them back to the defined default. Otherwise, every test will modify the system further until results get unpredictable.

There currently is just one handler for queueing scenarios:

• the script handler, which executes a local script

Driver Options

Name	Default	Description
queueing	false	If to invoke external actions to get hostname
queueing_timeout	3600	Timeout for queueing operations in seconds.
queueing_handlers	-	Glob to load external queueing handlers

Queueing Handler static

This handler only executes local commands. These could query remote databases or even issue more complex programs to obtain/release machines.

Parameters for request

Name	Default	Description
type	script
execute	-	Command to execute
match_hostname	^(.*)$	Regex to specify what to grab from output. Default: All
match_banner	-	Regex to specify optional banner to grab. Default: Nothing

If a banner is grabbed, it's contents are displaed after the message reporting the hostname. This field can be used for warnings or additional information like access to management interfaces (ILO, BMC, ...).

Parameters for release

Name	Default	Description
type	script
execute	-	Command to execute

The executed script gets the following environment variables:

• STATIC_HOSTNAME: Hostname or IP of the host to be released
