How to generate access token to login

Step 1: You can login to Kubernetes using access token.

To generate access token you need create a service account for Kubernetes dashboard service. To create dashboard service account with the below mentioned yaml file using vi or nano editor.

# kubernetes-dashboard-service-account.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: kubernetes-dashboard-admin-user
namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: kubernetes-dashboard-admin-user
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: kubernetes-dashboard-admin-user
namespace: kubernetes-dashboard
---
apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
name: kubernetes-dashboard-token
namespace: kubernetes-dashboard
annotations:
kubernetes.io/service-account.name: kubernetes-dashboard-admin-user

Step 2: Generate the access token using the following command

# kubectl apply -f kubernetes-dashboard-service-account.yaml

Following output is generated from the above command

Step 3: Once the token is generated, use the following command to get the access token.

# kubectl describe secret $(kubectl get secrets -n kubernetes-dashboard | grep kubernetes-dashboard-token | awk '{print $1}') -n kubernetes-dashboard

Step 4: From the above command, the output generated is given in screenshot below
