Nginx – Chef-solo cannot locate an nginx recipe template

amazon-web-serviceschefchef-solodeploymentnginx

I have been recently experimenting with Chef. I thought I would attempt to rebuild my personal web server using chef-solo. It's an AWS instance running the Amazon 64bit Linux AMI.

My first objective is to install nginx. I have cloned the Opscode cookbook repository, and am using their nginx cookbook.

My problem appears to be that chef-solo cannot find a template after it has started the process.

The command I'm using is

 chef-solo -j /etc/chef/dna.json

dna.json

{
  "nginx": {
    "user": "ec2-user"
  },
  "recipes": [ "nginx" ]
}

solo.rb

file_cache_path "/var/chef-solo"
cookbook_path "/var/chef-solo/cookbooks"

…the output

[root@ip-10-202-221-135 chef-solo]# chef-solo -j /etc/chef/dna.json

What am I doing incorrectly?

Best Answer

To fix you should probably add this to the beginning of your nginx default recipe:

directory "/etc/nginx/sites-available" do
    owner "root"
    group "root"
    mode "0755"
end

For what it's worth, I've been doing the same thing with Chef (Hosted), EC2 and Amazon Linux. It took me a while, but I figured out that it was almost always easier to just roll my own recipes. I now have a dozen that I now use, and I've removed all the Opscode shared ones I initially tried.

In fact, my default recipe for nginx has just one line: 

`package "nginx"`

So one way to go is to install that on your server first with yum install nginx and then grab the default config file it created. Bring that back to your cookbook as a template, and put in ERB lines to customize any values for your needs.
