• Node ports help forward traffic to the respective pods.
    • Am able to access the applications using the IP of any of the nodes and the port.
      • However, users want one URL to navigate to to access the application.
  • A solution is to create a VM to act as a load balancer, using nginx or similar tools.
    • Then routing traffic from the load balancer to the specific nodes.
    • Can also use cloud platforms such as Google Cloud Platform and AWS
    • The Front-End services would be set to type: LoadBalancer. The service-definition.yml file would look like the following and is Only supported on certain cloud platforms: ``` apiVersion: v1 kind: Service metadata: name: myapp-service

spec: type: LoadBalancer ports: - targetPort: 80 port: 80 nodePort: 30008

* Good example service definition file:

apiVersion: v1 kind: Service metadata: name: webapp-service namespace: default spec: ports:

  • nodePort: 30080 port: 8080 targetPort: 8080 selector: name: simple-webapp type: NodePort ```
  • You would then apply the file with kubectl apply -f <filename> / kubectl create -f <filename>
