nmuxj

Story

That is a simple go rest api that aim to be a kind of webhook proxy for the cloud-init web calls from the VM's when they are ready for the first time provisioning.

Then all the vm's calling this simple api and when it reach all the expected calls then its perform a jenkins remote call to trigger a defined job with the provided job parameters.

This make it possible to run provision jobs with jenkins as part of a cloud init run.
