How to Implement RBAC in Kubernetes? A Step-By-Step Guide
The following are the steps that guides you in implementing the RBAC in kubernetes:
Step 1: Create a Role
- Firstly create a yaml manefist file with defining role resource that allows to access the pods.
- For example, the yaml file named as pod-reader that allows in read access to pods:
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: <namespace> # If specific to a namespace
name: pod-reader
rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["get", "list"]
Step 2: Create a Role Binding
- Bind the role to a user, group or service account.
- For example, create a rolebinding named yaml file “read-pods” to bind the pod-reader role to a user named user1. The read-pods.yaml file code looks as follows:
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: <namespace> # If specific to a namespace
name: pod-reader
rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["get", "list"]
Step 3: Apply the YAML files
- Apply the YAML files containing the role and roleBinding using the following command:
kubectl apply -f role.yaml
kubectl apply -f rolebinding.yaml
Step 4: Verify the Access
- Verfiy that the user1 can now read pods or not with the following command:
kubectl get pods --as user1
