Is it possible to set a PriorityClassName for the ArgoCD pods/deployments?

[kastl-ars]

A customer of ours recently had an outage where some nodes crashed after an update. As a results, a discussion was started on how to prevent argoCD being unreachable and how to make the whole cluster more resilient.

One thing that came up was using a PriorityClass for all pods/deployments/... of ArgoCD, to make sure that ArgoCD has a higher priority than other pods.

I have found no mention of priorityclasses in the documentation, so I was wondering if setting this is possible.

Or if this is not possible, maybe because there is a disadvantage and a better way to achieve more resilience?

I look forward to hearing how others are solving such issues.

Kind Regards,
Johannes
