Description
This module provides Puppet tasks and functions that use vmfloaty to interact with Puppet's vmpooler application.
Setup
Currently, this module requires that the vmfloaty gem is installed on the target node and that any necessary configuration is present in ~/.vmfloaty.yml:
url: https://vmpooler.example.com
token: '<vmpooler_api_token>'
Usage
The simplest way to test out the module is to run it against localhost with Bolt:
$ bolt task run floaty::get platform=centos-7-x86_64 count=2 --nodes localhost
Started on localhost...
Finished on localhost:
{
"nodes": [
"t8vhnjwomf59htp.example.com",
"ft0jdxrgv899r0r.example.com"
]
}
Successful on 1 node: localhost
Ran on 1 node in 0.52 seconds
Reference
Tasks
floaty::get
This task retrieve a set of nodes from vmpooler.
Parameters
platform : Which VM pool to retrieve nodes from (ie. centos-7-x86_64)
count : How many nodes to retrieve (defaults to 1 if not specified)
Output
On success, the result will contain a nodes key, which is an array of the retrieved nodes. On failure, the result will contain an _error key describing the problem.
Functions
floaty::get(platform, count)
This function retrieves a node or list of nodes from vmpooler by running floaty locally.
Parameters
platform : Which VM pool to retrieve nodes from (ie. centos-7-x86_64)
count : How many nodes to retrieve (defaults to 1 if not specified)
Value
If one node was requested, the value is the name of node retrieved. If multiple nodes were requested, the value is an array of retrieved node names.
Limitations
This module is currently only intended to solve a very specific use case, so it's probably quite fragile in cases where floaty itself isn't set up properly.
Currently, the floaty::get task only supports retrieving nodes from one pool at a time.
Use with caution.

What are tasks?
Modules can contain tasks that take action outside of a desired state managed by Puppet. It’s perfect for troubleshooting or deploying one-off changes, distributing scripts to run across your infrastructure, or automating changes that need to happen in a particular order as part of an application deployment.
