Overriding OS fact with external one

Hi,

Short notice article. We had a issue in which the traefik module code was not running because of a wrong os fact. Although the image is Ubuntu 14.04, facter returns it like:

{
  architecture => "amd64",
  family => "Debian",
  hardware => "x86_64",
  name => "Debian",
  release => {
    full => "jessie/sid",
    major => "jessie/sid"
  },
  selinux => {
    enabled => false
  }
}

I honestly don’t know why this happens since on rest of machines it works good, the way to fix it fast is by defining an external fact in /etc/facter/facts.d

Create a file named os_fact.json, for example, that will contain this content:

{ 
   "os":{ 
      "architecture":"amd64",
      "distro":{ 
         "codename":"trusty",
         "description":"Ubuntu 14.04.6 LTS",
         "id":"Ubuntu",
         "release":{ 
            "full":"14.04",
            "major":"14.04"
         }
      },
      "family":"Debian",
      "hardware":"x86_64",
      "name":"Ubuntu",
      "release":{ 
         "full":"14.04",
         "major":"14.04"
      },
      "selinux":{ 
         "enabled":"false"
      }
   }
}

And it’s fixed.

Cheers
