chef-extensions

Commands useful for checking internet connectivity, VM presence etc.

Install it

gem install chef-extensions

How it works

I'm only using chef-solo, so after installing the gem, require it in config/solo.rb.

Then, in your cookbooks or providers, use one of the existing methods, eg:

if Chef::Extensions.wan_up?
  # do some work...
end

If you want to see use-cases for the gem, check out apt-cookbook.

Known issues / concerns

Google's DNS very rarely doesn't to pings. It's reliable 99.9% of the time, which is good enough. Would defintely benefit from having 2 IPs and falling back to the second one before returning false.

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
