CKS - different compute offering for nodes

[baltazorbest]

Hello everyone.

We are about to test CKS in CloudStack and noticed that we are missing the ability to add worker nodes with different compute offerings. We need this because we have applications in Kubernetes with different requirements — for example, a database needs more RAM than a backend. At the moment, this can be done by changing the compute offering for worker nodes that were already created, but this is not intuitive.

@baltazorbest you can choose offering for specific worker node starting from 4.21 release

Yes, I can, but what I mean is being able to add new worker nodes with different compute offerings to one cluster. For example:

• 5 worker nodes with 4 CPUs and 16 GB RAM
• 10 worker nodes with 16 CPUs and 128 GB RAM
  etc.

@baltazorbest Can you check the following, this should help you add additional worker nodes with different compute offerings
