How to generate Kubernetes token : #

In order to generate the Kubernetes token, you need to follow below steps:

1. Choose your k8s cluster:

kubectl config use-context my_cluster_name

2. Make default account the cluster administrator:

kubectl create clusterrolebinding default-admin –clusterrole cluster-admin –serviceaccount=default:default -n default

3. Fetch Host IP detail:

   export CURRENT_CONTEXT=$(kubectl config current-context) && export CURRENT_CLUSTER=$(kubectl config view -o go-template="{{$curr_context := "$CURRENT_CONTEXT" }}{{range .contexts}}{{if eq .name $curr_context}}{{.context.cluster}}{{end}}{{end}}") && echo $(kubectl config view -o go-template="{{$cluster_context := "$CURRENT_CLUSTER"}}{{range .clusters}}{{if eq .name $cluster_context}}{{.cluster.server}}{{end}}{{end}}")

NOTE: Use the IP generated by this command to configure the datasource in Gathr Analytics in the later section of this article.

4. Get Kubernetes bearer token:

   echo $(kubectl get secret -o go-template=’{{index .data “token” }}’ $(kubectl get sa default -o go-template="{{range .secrets}}{{.name}}{{end}}")) | base64 –decode

NOTE: Save the generated Bearer Token to configure the datasource in Gathr Analytics in the later section of this article.
