 # ReplicaSets with YAML
 
-## Step-01: Understand Labels & Selectors
-- Discuss about Labels and Selectors
-
-## Step-02: Create ReplicaSet
-- Create ReplicaSet with 3 Replicas
-- Verify pod names, one pod which we created using `pod-definition.yml` will be part of replicaset because it also has `labels: app=myapp`
-```
-kubectl apply -f replicaset-definition.yml 
-kubectl get rs
-kubectl get pods
-```
-- Delete the pod which we created using `pod-definition.yml`
-- ReplicaSet immediately creates the pod. 
-```
-kubectl delete pod myapp-pod
-kubectl get pods
-```
+## Step-01: Create ReplicaSet Definition
 - **replicaset-definition.yml**
 ```yml
 apiVersion: apps/v1
 kind: ReplicaSet
 metadata:
-  name: myapp-rs
+  name: myapp2-rs
 spec:
-  replicas: 3
-  selector:
+  replicas: 3 # 3 Pods should exist at all times.
+  selector:  # Pods label should be defined in ReplicaSet label selector
     matchLabels:
-      app: myapp
+      app: myapp2
   template:
     metadata:
-      name: myapp-pod
+      name: myapp2-pod
       labels:
-        app: myapp
+        app: myapp2 # Atleast 1 Pod label should match with ReplicaSet Label Selector
     spec:
       containers:
-      - name: myapp
+      - name: myapp2
         image: stacksimplify/kubenginx:2.0.0
         ports:
           - containerPort: 80
-```
+```
+## Step-02: Create ReplicaSet
+- Create ReplicaSet with 3 Replicas
+```
+# Create ReplicaSet
+kubectl apply -f 02-replicaset-definition.yml
+
+# List Replicasets
+kubectl get rs
+```
+- Delete a pod
+- ReplicaSet immediately creates the pod. 
+```
+# List Pods
+kubectl get pods
+
+# Delete Pod
+kubectl delete pod <Pod-Name>
+```
+
+## Step-03: Create NodePort Service for ReplicaSet
+```yml
+apiVersion: v1
+kind: Service
+metadata:
+  name: replicaset-nodeport-service
+spec:
+  type: NodePort
+  selector:
+    app: myapp2
+  ports:
+    - name: http
+      port: 80
+      targetPort: 80
+      nodePort: 31232  
+```
+- Create NodePort Service for ReplicaSet & Test
+```
+# Create NodePort Service
+kubectl apply -f 03-replicaset-nodeport-servie.yml
+
+# List NodePort Service
+kubectl get svc
+
+# Get Public IP
+kubectl get nodes -o wide
+
+# Access Application
+http://<Worker-Node-Public-IP>:<NodePort>
+http://<Worker-Node-Public-IP>:31232
