In order for any Kubernetes object, including other pods, to access the
podinfo pod, we have to expose on the Kubernetes network the network ports that should be accessed. When using the Application Load Balancer on EKS, the service type should be
NodePort. In more complex architectures, there are other load balancing methods that can be used.
You can create a NodePort Service yaml (as specified by the ALB ingress controller) by running the following command and adding the manifest to your repository as
kubectl create service nodeport podinfo --namespace podinfo --tcp=9898:9898 --dry-run -o yaml > podinfo-service.yaml
Alternatively, you can copy and paste the service as defined below to a new file called
apiVersion: v1 kind: Service metadata: name: podinfo namespace: podinfo spec: type: NodePort selector: app: podinfo ports: - name: http port: 9898 protocol: TCP
