Supported Packet Managers

  • apt
  • yum
  • look at example and send PRs

Which packet manager will be used depends on what ohai (or chef) reports as platform_family for a node. So it should work if your node is of type 'debian' (=> apt), 'fedora' or 'rhel' (=> yum)

Requirements

  • SSH access
  • Chef(-Server) or anything else which supports search(:node, "*:*") (not required when you use -m)
  • when -m option is given, ohai has to be installed on the node ( sudo gem install ohai --no-ri --no-rdoc )

Installation

Add this line to your application's Gemfile:

gem 'knife-pkg'

And then execute:

$ bundle

Or install it yourself as:

$ gem install knife-pkg

Overview

The plugin inherits from Knife::Ssh, so almost all options and configuration settings are supported.

The following sub-commands are provided:

knife pkg show updates SEARCH (options)
knife pkg install updates SEARCH (options)
