Initial Configuration Steps:

1. Set Up Namespace:

   • Use namespaces to organize and isolate resources:

     kubectl create namespace dev

2. Configure Role-Based Access Control (RBAC):

   • Create a role with specific permissions:

     apiVersion: rbac.authorization.k8s.io/v1
     kind: Role
     metadata:
       namespace: dev
       name: dev-role
     rules:
     - apiGroups: [""]
       resources: ["pods"]
       verbs: ["get", "list", "watch"]

   • Bind the role to a user or group:

     apiVersion: rbac.authorization.k8s.io/v1
     kind: RoleBinding
     metadata:
       name: dev-rolebinding
       namespace: dev
     subjects:
     - kind: User
       name: dev-user
     roleRef:
       kind: Role
       name: dev-role
       apiGroup: rbac.authorization.k8s.io

3. Set Up Networking:

   • Deploy a network plugin (e.g., Calico or Flannel) for cluster communication:

     kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml

4. Install Kubernetes Dashboard:

   • Deploy the official dashboard:

     kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.0/aio/deploy/recommended.yaml

   • Access the dashboard:

     kubectl proxy
