Previously it was expected that the timeout setting should be passed when
determining whether a VM was ready. However this should be in the pool
configuration and is not required to be a method parameter.
Previously many of the methods did not have a pool name passed as a parameter.
While this may be ok for the vSphere provider, it may not for other providers.
This commit changes the base provider to consistently use (pool,vm,other..) as
method parameters. This commit also updates the base spec tests as well.
Additionally:
- Updated documentation around expected error states
- Updated documentation to be more consistent in format
- Added snapshot and disk manager functions and unit tests
- Update the initialization method to take in a more formal defintion with
required global objects for metrics, logging and configuration
- Added helper functions
- logger : Allows providers to log information as per Pool Manager
- metrics : Allows providers to submit metrics as per Pool Manager
- provider_options : Allows providers to access initialization options for a
provider
- pool_config : Get the configuration for a specific pool
- provider_config : Get the configuration of this specific provider
- global_config: Get the VMPooler global configuration

vmpooler
vmpooler provides configurable 'pools' of instantly-available (running) virtual machines.
Usage
At Puppet, Inc. we run acceptance tests on thousands of disposable VMs every day. Dynamic cloning of VM templates initially worked fine for this, but added several seconds to each test run and was unable to account for failed clone tasks. By pushing these operations to a backend service, we were able to both speed up tests and eliminate test failures due to underlying infrastructure failures.
Installation
Prerequisites
vmpooler requires the following Ruby gems be installed:
It also requires that a Redis server exists somewhere, as this is the datastore used for vmpooler's inventory and queueing services.
Configuration
The following YAML configuration sets up two pools, debian-7-i386 and debian-7-x86_64, which contain 5 running VMs each:
---
:vsphere:
server: 'vsphere.company.com'
username: 'vmpooler'
password: 'swimsw1msw!m'
:redis:
server: 'redis.company.com'
:config:
logfile: '/var/log/vmpooler.log'
:pools:
- name: 'debian-7-i386'
template: 'Templates/debian-7-i386'
folder: 'Pooled VMs/debian-7-i386'
pool: 'Pooled VMs/debian-7-i386'
datastore: 'vmstorage'
size: 5
- name: 'debian-7-x86_64'
template: 'Templates/debian-7-x86_64'
folder: 'Pooled VMs/debian-7-x86_64'
pool: 'Pooled VMs/debian-7-x86_64'
datastore: 'vmstorage'
size: 5
See the provided YAML configuration example, vmpooler.yaml.example, for additional configuration options and parameters.
Running via Docker
A Dockerfile is included in this repository to allow running vmpooler inside a Docker container. A vmpooler.yaml configuration file can be embedded in the current working directory, or specified inline in a VMPOOLER_CONFIG environment variable. To build and run:
docker build -t vmpooler . && docker run -e VMPOOLER_CONFIG -p 80:4567 -it vmpooler
API and Dashboard
vmpooler provides an API and web front-end (dashboard) on port :4567. See the provided YAML configuration example, vmpooler.yaml.example, to specify an alternative port to listen on.
API
vmpooler provides a REST API for VM management. See the API documentation for more information.
Dashboard
A dashboard is provided to offer real-time statistics and historical graphs. It looks like this:
Graphite is required for historical data retrieval. See the provided YAML configuration example, vmpooler.yaml.example, for details.
Command-line Utility
- The vmpooler_client.py CLI utility provides easy access to the vmpooler service. The tool is cross-platform and written in Python.
- vmfloaty is a ruby based CLI tool and scripting library written in ruby.
Vagrant plugin
- vagrant-vmpooler Use Vagrant to create and manage your vmpooler instances.
