The credentials needed to query jenkins are going to be passed into the script via the Vendor_Files role, which means the credentials need to be stored in the secrets repo

No comment on the code yet but noting the typo in the filename which will need to be fixed :-)

At the moment it dumps the inventory results into DockerInventory.json which should stay in the same directory as inventory.yml.

I would like a system in place to keep this inventory updated. Could do an automated github action which runs the script, if it detects differences between the output and the existing DockerInventory.json file, it makes a pr to update it. Either way this is beyond this pr
