Goals 

The goal of the PoC is to understand alternate architecture options of running ArgoCD as a multi-tenant service, learn about resource requirements, test the isolation provided by different approaches.

PoC architectures

Bin packing

One ArgoCD instance per organization.

1. Automate creation of argoCD instances for different users. For the PoC a simple script can also be used to prove that concept is doable.
2. Find resource requirements to be able to right size the ArgoCD instances.
3. Test scalability limits. Discover any limits to the number of instances that can be run.

Multi-tenancy via ArgoCD RBAC

One argoCD instance on the cluster that does multi-tenancy with argoCD RBAC.

1. Automate creation of RBAC definitions for different users. Similar to above a simple script to prove the concept should be enough.
2. Test and document places where the isolation fails
3. Find resource requirements, scalability limits.
