Installation fails on k8s 1.22

[andrej-urvantsev]

As of 1.22 rbac.authorization.k8s.io/v1beta1 is removed, instead rbac.authorization.k8s.io/v1 must be used: https://kubernetes.io/docs/reference/using-api/deprecation-guide/#rbac-resources-v122

Affected files:

• fluent-bit-role.yaml
• fluent-bit-role-binding.yaml

Thanks for reporting @LazyStone , I'll add a note in the getting started for the role / role-binding. Since it seems most cloud providers are still on 1.20 - 1.21 will switch this to the new default after a month or so
