GCP Deployment Manager third party resources

Just wanted to make sure my understanding is correct. Based on my research, Deployment Manager can integrate with third party APIs, although is a BETA feature at this moment.

So my question is, can Deployment Manager automate Google resources and also external resources(e.g. on premises resource using third party API)?

https://cloud.google.com/deployment-manager/docs/configuration/type-providers/creating-type-provider

https://cloud.google.com/deployment-manager/docs/configuration/type-providers/process-adding-api

Absolutely but after you successfully register the third party API as a type provider (not manage by Google).

Take into account:

1. your API is map to http methods

get htttp://onpremises.com/api/yourresource
delete htttp://onpremises.com/api/yourresource
put htttp://onpremises.com/api/yourresource
post htttp://onpremises.com/api/yourresource

2. API's descriptor document, something like this

3. your config.yaml

resources:
- name: my-api
  type: project/your-api:yourresource
  properties:
  - name: Jane
    website: onpremises.com/api

This will cause a http post request to be made by the deployment-manager to your API.
