+# Monitoring EKS using CloudWatch Container Insigths
+
+## Step-01: Deploy our Sample to generate Load
+```
+# Deploy
+kubectl apply -f kube-manifests
+
+# Access Application
+http://<Network-Load-Balancer-URL>/app1/index.html
+```
+
+## Step-02: Associate CloudWatch Policy to our EKS Worker Nodes Role
+- Go to Services -> EC2 -> Worker Node EC2 Instance -> IAM Role -> Click on that role
+```
+# Sample Role ARN
+arn:aws:iam::180789647333:role/eksctl-eksdemo1-nodegroup-eksdemo-NodeInstanceRole-1FVWZ2H3TMQ2M
+
+# Policy to be associated
+Associate Policy: CloudWatchAgentServerPolicy
+```
+
+## Step-03: Install Container Insights
+
+### Deploy CloudWatch Agent and Fluentd as DaemonSets
+- This command will 
+  - Create the Namespace amazon-cloudwatch.
+  - Create all the necessary security objects for both DaemonSet:
+    - SecurityAccount.
+    - ClusterRole.
+    - ClusterRoleBinding.
+  - Deploy Cloudwatch-Agent (responsible for sending the metrics to CloudWatch) as a DaemonSet.
+  - Deploy fluentd (responsible for sending the logs to Cloudwatch) as a DaemonSet.
+  -  Deploy ConfigMap configurations for both DaemonSets.
