dynamic inventory tiered groups

[Marc Pascual]

Hello!

I'm new to ansible, and I am trying to figure out how the json output should look like if I have a flat-file inventory source like:

# application:environment=hostlist

heroes:marvel=thor hulk stark cap

heroes:dc=supe bats flash robin

colors:primary=red blue yellow

colors:secondary:green orange violet

lol:~/scripts/python bash-3.2$ ./inv.py --list

{

    "heroes": {

        "dc": [

            "supe",

            "bats",

            "flash",

            "robin"

        ],

        "marvel": [

            "thor",

            "hulk",

            "stark",

            "cap"

        ]

    },

    "colors": {

        "primary": [

            "red",

            "blue",

            "yellow"

        ],

        "secondary": [

            "green",

            "orange",

            "violet"

        ]

    }

}

I am looking to run one liners against groups and sub groups such as:

 

ansible -i ~/bin/inv.py colors -m 'uname -n'

(runs uname against red, blue, yellow, green, orange, violet)

ansible -i ~/bin/inv.py primary -m 'uname -n'

(runs uname against green, orange, violet)

Or, I could be going about this all wrong. Can anyone give me a hint? 

cheers,

Marc
