Yesterday Opscode, the company behind Chef, announced the first ever chef cookbook contest. In order to participate in the contest you will need to write a new cookbook and submit it by the end of September; this is going to be a little tricky as there are many cookbooks already available on the community site. So this is a great idea and it will take care of the few applications that don’t already have chef cookbooks. The cookbooks which shows off the awesome Chef features will have better chances to win. The prizes are also interesting: iPad, gift cards, etc. Here are the full details and rules of the contest: http://www.opscode.com/blog/2011/08/22/cookbook-contest/

So if you have an idea for a chef cookbook, now it’s the time to start working on it. I’m offering my help for free for all my blog readers: I will help you write a cookbook by implementing your ideas; help reviewing it or suggest improvements, or whatever else you might need help with. Use the contact form to email me (or DM me on twitter) and let me know how I can help.

If you don’t have time to write a new cookbook but you have a great idea for a cookbook that is missing from the opscode community site, please post it bellow in the comments section and I’m sure some of my blog readers will help create it.

Again this is a brilliant idea from Opscode and it creates a win-win situation for everyone. I’m just curious, is this the first idea from their new community manager? If this is the case, great job Jesse .

A few days ago Opscode released a security fix for chef server 0.10.0 and 0.9.16 and this post will show how upgrade to chef-server 0.10.2. First start by backing up your data. Seriously. In the past I’ve had serious problems when performing similar upgrades (even a minor one like this that looks harmless), and even if now opscode are much better with this process it never hurts to be precautions. Since I use a rubygem install the next steps will focus on this type of installation; if you are using distribution or opscode packages this will not be very helpful as probably packages are not yet available for this upgrade; once they will replace the gem upgrade part with the deb/rpm upgrade and you should be set.

1. Stop all the chef related services

Here is a handy command that will stop all the possible chef server related services:
for svc in server server-webui solr expander
do
sudo /etc/init.d/chef-${svc} stop
done

Here are the slides from my presentation about Chef at the SF Bay Area Large-Scale Production Engineering meetup group. Accordingly to the organizers from Yahoo, there were 90 people present. If you are in the San Francisco Bay Area and passionate about infrastructure you should definitely join this group. Highly recommended!

I’ve just released a simple chef cookbook that will install nodejs from source. You can check it out directly from github or download it from the opscode cookbook site. Let me know what you think if you find it useful.
