Is your task related to a problem? Please describe.
Compatibility matrix between ArgoCD Operator and ArgoCD is missing.
Describe the solution you'd like
A compatibility matrix for each new released version of ArgoCD and their corresponding ArgoCD Operator version, also this should be done for previous releases as well.
Describe alternatives you've considered
If not a compatibility matrix, than a clear state in the release notes about ArgoCD and ArgoCD Operator corresponding versions available.
Additional context
For example I have updated to ArgoCD 2.9.2 with version Operator version 0.7 just to find out that these versions are incompatible, and that Operator 0.9 is needed for that specific version of ArgoCD.
To what I know, ArgoCD version 2.x exhibits a direct compatibility with the ArgoCD operator version 0.x. This compatibility matrix implies that if you desire to utilize ArgoCD version 2.9, you necessitate ArgoCD operator version 0.9, and this pattern extends accordingly.
The rigid interdependency arises due to the fact that the ArgoCD operator encapsulates and integrates the ArgoCD Custom Resource Definitions (CRDs) essential for proper operation. Hence, upgrading ArgoCD versions often necessitates a corresponding update to the operator to maintain alignment with the CRDs.
However, I encountered a scenario where I successfully deployed ArgoCD version 2.10.2 while employing ArgoCD operator version 0.8.0. This configuration diverges from the established compatibility matrix, but it proved viable for my specific environment.
To achieve this, I manually obtained the CRDs tailored for ArgoCD version 2.10 and substituted them for the existing CRDs, which were configured for version 2.8. It's important to acknowledge that this approach may not be advisable for production environments due to potential risks associated with compatibility mismatches. Nonetheless, for the purposes of testing, this workaround functioned seamlessly within my testing environment
Thank you for your quick response!
