Response Structure

This endpoint has no constant keys in its response. Instead, each key in the response object is the name of an OS, and the value is a string that names the directory where the ISO source can be found. These directories sit under /var/www/files/ on the Traffic Ops host machine by default, or at the location defined by the kickstart.files.location Parameter of the Traffic Ops server’s Profile, if it is defined.

Configuration File

The data returned from the endpoint comes directly from a configuration file. By default, the file is located at /var/www/files/osversions.json. The directory of the file can be changed by creating a specific Parameter named kickstart.files.location in configuration file mkisofs.

The format of the file is a JSON object as described in Response Structure.

#871 Example osversions.json file
    "CentOS 7.2": "centos72"

The legacy Perl Traffic Ops used a Perl configuration file located by default at /var/www/files/osversions.cfg. A Perl script is provided to convert the legacy configuration file to the new JSON format. The script is located within the Traffic Control repository at traffic_ops/app/bin/osversions-convert.pl.

#872 Example usage of conversion script
./osversions-convert.pl < /var/www/files/osversions.cfg > /var/www/files/osversions.json
