Amazon EKS - Create Role Binding in Kubernetes

Role Binding in Amazon EKS is the process to assign the role created in the previous step to the service account for the deployment of NCache Operator.

Create Manifest File for Role Binding

Declaration of the YAML file, role_binding.yaml, is shown below:

Note

The parameters required to create this YAML file, ready to be deployed, are explained in the Properties section.

kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: ncache-operator
subjects:
- kind: ServiceAccount
  name: ncache-operator
roleRef:
  kind: Role
  name: ncache-operator
  apiGroup: rbac.authorization.k8s.io

In this declaration, the subjects and roleRef bind the two entities together.

Deploy Role Binding in Amazon EKS

Deploy the created role_binding.yaml in Kubernetes cluster to successfully assign roles to the service account.

kubectl create -f [dir]/role_binding.yaml
