Package Agent
The package agent that lets you install, uninstall, update, purge and query the status of packages on your system.
The package agent does not do any management of packages itself. Instead it uses the functionality defined in MCollective::Util::Package classes to perform the actions. By default the Package agent ships with a PuppetPackage util class, but creating your own is as simple as adding a new class to util/package/ and implementing the #install, #uninstall, #purge, #update and #status methods.
Installation
Follow the basic plugin install guide.
Configuration
There is one plugin configuration setting for the package agent.
- provider - The Util class that implements the install, uninstall, purge, update and status behavior. Defaults to 'puppet'
General provider configuration options can then also be set in the config file.
plugin.package.provider = puppet
# Puppet provider specific options
plugin.package.puppet.allowcdrom = true
Usage
% mco rpc package install package=nano
* [ ============================================================> ] 4 / 4
Summary of Ensure:
2.0.9-7.el6 = 4
Finished processing 4 / 4 hosts in 18176.83 ms
% mco package nano uninstall
* [ ============================================================> ] 4 / 4
Summary of Ensure:
absent = 4
Finished processing 4 / 4 hosts in 393.68 ms
% mco rpc package install package=openssl version=0.9.8k-7ubuntu8
* [ ============================================================> ] 4 / 4
Summary of Ensure:
0.9.8k-7ubuntu8 = 4
Finished processing 4 / 4 hosts in 18176.83 ms
Data Plugin
The Package agent also supplies a data plugin which uses the Package agent to check the current status of a package. The data plugin will set installed to true/false if the package is not installed or not, and will set status to the currently installed version if it is present and can be used during discovery or any other place where the MCollective discovery language is used.
mco rpc rpcutil ping -S "package('mypackage').installed=false"
mco rpc rpcutil ping -S "package('mypackage').status=3.2-1"
Extending
The default package agent achieves platform portability by using the Puppet provider system to support package managers on all platforms that Puppet supports.
If however you are not a Puppet user or simply want to implement some new method of package management you can do so by providing your own backend provider for this agent.
The logic for the Puppet version of this agent is implemented in Util::Package::PuppetPackage, you can create a custom package implementation that overrides #install, #uninstall, #update, #purge and #status.
This agent defaults to Util::Package::PuppetPackage but if you have your own you can configure it in the config file using:
plugin.package.provider = puppet
