Detailed Description
Diego API api to add diego cell or Create BOSH VM on which containers can be deployed on .

Currently a new diego cell has to be provisioned manually on Vsphere environment

Context
. We wish to automate it using scripts so that based on load a new diego cell can be provisioned automatically on cloud environments like Azure/AWS etc.

This will help users to not only scale containers but also the underlying VMs on which containers are deployed on

Possible Implementation
Bosh could provide apis to provision new diego Cells

Complexity
Medium

Hey @viju2008!

VM management and scaling isn't really in the scope of diego's responsibilities. I don't believe BOSH provides any APIs for triggering scale out of instance groups at this time either, so I'd suggest adding a feature request to bosh itself for the live instance-group scale-up/down API.

After that, you could potentially write something that watches scaling KPI metrics for cells on the firehose, and trigger the BOSH scaling API with any custom logic you have for ensuring the events don't happen in an inopportune time, or scale out of control. There's a lot of potential for unexpected issues when doing this though, so I'd proceed with a lot of caution.

Going to close this out, since I don't think it's something we'd ever provide via diego specifically.
