 This repository contains a set of Yaml files to deploy Fluent Bit which consider namespace, RBAC, Service Account, etc.
 
 ## Getting started
 
 [Fluent Bit](http://fluentbit.io) must be deployed as a DaemonSet so that it will be available on every node of your Kubernetes cluster. To get started run the following commands to create the namespace, service account and role setup:
 
+
+For Kubernetes v1.21 and below
+
 ```
 $ kubectl create namespace logging
 $ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-service-account.yaml
 $ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role.yaml
 $ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role-binding.yaml
 ```
 
+For Kubernetes v1.22 and above
+
+```
+$ kubectl create namespace logging
+$ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-service-account.yaml
+$ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role-1.22.yaml
+$ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role-binding-1.22.yaml
+```
+
+
 If you are deploying fluent-bit on openshift, you additionally need to run:
 
 ```
 $ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-openshift-security-context-constraints.yaml
 ```
 
+
 #### Fluent Bit to Elasticsearch
 
 The next step is to create a ConfigMap that will be used by our Fluent Bit DaemonSet:
