I started working on installing MongoDB with Chef-solo…here are the steps, errors and fixes I came up with.
Here is the Cookbook i used: git@github.com:edelight/chef-mongodb.git
First I ran into an error with the install wanting to use APT to download the packages. The error read something like “APT cookbook/dependancy not found.” Thats not the exact wording but ive already lost the true error because the chef-stacktracefile.out file gets written over when you run chef-solo. I need to set that to append from now on so i can track the errors better.
I looked in the 10gen_repo.rb recipe and found where it was looking for the APT cookbook before it did anything that looked at what OS im on. I just commented that line out and gave it another whirl. this time i got another error…

The stacktrace revealed this: ArgumentError: Unable to create Chef::RunList::RunListItem from String:”recipe [mongodb::10gen_repo]”: must be recipe[] or role[]
I wasn’t quite sure what was going on with this one but from the error I figured i needed to look into the 10gen_repo.rb and see what it was doing. This recipe sets up the repositories for stable 10gen packages. i looked in the README file to see if there were any instructions related to this recipe and found this…
Adds the stable 10gen repo for the corresponding platform. Currently only implemented for the Debian and Ubuntu repository.
Usage: just add recipe[mongodb::10gen_repo] to the node run_list before any other MongoDB recipe, and the mongodb-10gen stable packages will be installed instead of the distribution default.
So all I had to do now was add this to my mongodb.json file that im calling when I run chef-solo. That looks like this now…
{
“run_list”: [“recipe[mongodb::10gen_repo]”, “recipe[mongodb]”]
}
Trying it again….
