Building packages is a task that every system administrator will end up doing. Most of the time this is not a very interesting task but someone has to do it, right? Normally you will end up modifying and tweaking based on your own needs an existing package that was built by the maintainers of the Linux distribution that you are using. In time you might even become familiar with the packaging system you are using (rpm, deb, etc.) and you will be able to write a spec file and start from scratch and build a new package if you need to. Still, this process is complicated and requires a lot of work.

Luckily, Jordan Sissel has built a tool called FPM (Effing Package Management), exactly for this: to ease the pain of building new packages; packages that you will use for your own infrastructure and you want them customized based on your own needs; and you don’t care about upstream rules and standards and other limitations when building such packages. This can be very useful for people deploying their own applications as rpms (or debs) and can simplify a lot of the process of building those packages.

FPM can be easily installed on your build system using rubygems:
gem install fpm

Once installed you can use fpm to build packages (targets):

• deb
• rpm
• solaris

from any of the following sources:

• directory (of compiled source of some application)
• gem
• python eggs
• rpm
• node npm packages

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 .

If you used vagrant (great tool, right?) you have probably downloaded a basebox from some remote location to get you started. This is a great quick start, and there are many good boxes out there that you can use; vagrantbox.es does a great job in listing various public vagrant boxes. But if you are like me, you probably will want to customize the boxes you are using; you might want to install them from scratch based on your own little/or/big customizations. Well if you are like that, then you will be happy to hear that Patrick Debois had exactly the same problem when he decided to write veewee. And veewee is exactly that missing part of vagrant that allows you to easily build your own vagrant boxes from scratch.

So let’s see how we can use veewee. I’m assuming you already have vagrant installed (and virtualbox), but if you don’t please install them first. To install veewee we just have to install the veewee gem:
gem install veewee
once you installed veewee you can see a new task added to vagrant: basebox.
