-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

-The next step is to create a ConfigMap that will be used by our Fluent Bit DaemonSet:
-
-```
-$ kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/output/elasticsearch/fluent-bit-configmap.yaml
-```
-
-The default configmap assumes that dockershim is utilized for the cluster. If a CRI runtime, such as containerd or CRI-O, is being utilized, the [CRI parser](https://github.com/fluent/fluent-bit/blob/master/conf/parsers.conf#L106-L112) should be utilized. More specifically, change the `Parser` described in `input-kubernetes.conf` from docker to cri.

 ```
 
-### Note for Kubernetes < v1.16
-
-For Kubernetes versions older than v1.16, the DaemonSet resource is not available on `apps/v1` , the resource is available on `apiVersion: extensions/v1beta1` . Our current Daemonset Yaml files uses the new `apiVersion`.
-
-If you are using and older Kubernetes version, manually grab a copy of your Daemonset Yaml file and replace the value of `apiVersion` from:
-
-```yaml
-apiVersion: apps/v1
-```
-
-to
-
-```yaml
-apiVersion: extensions/v1beta1
-```

-### Fluent Bit to Elasticsearch on Minikube

 [Helm](https://helm.sh) is a package manager for Kubernetes and allows you to quickly deploy application packages into your running cluster. Fluent Bit is distributed via a helm chart found in the Fluent Helm Charts repo: [https://github.com/fluent/helm-charts](https://github.com/fluent/helm-charts).
