Ask HN: Tools to run, manage, track SaaS service deployments?

Every multi-tenant SaaS or PaaS (cloud) needs to track which user deployed which services, when, for how long. I'm seeking existing technology to do this.

Features:

* specify what services are available

* for each service specify the deployment steps (e.g. script) for creating, starting, stopping, checking health, removing a service

* upon user request or some other trigger, schedule a service's deployment steps

* execute and monitor status of deployment steps

* should have a cli and/or REST API

* track deployment status in a database for easy persistence

* run periodic health checks

My preference is to have a Python component, perhaps a Django app, but I'm open to any other implementation that is easily docker deployable. I have already implemented a Django app because last time I checked there were no ready made tools available. Not sure if I should continue investing in it.

PS: I know there are some potentially applicable tools, but they are either too specific in use case (e.g. rancher, terraform), or too complex (e.g. puppet, chef).
