simple-internal

Internal Load-Balancer

This example creates an echoheaders deployment on your cluster, which listens on port 8080 and is exposed through a service available only within the VPC.

• Verify the the subnet where the load balancer needs to be deployed has the OskK8sRole/service.internal tag (with any value).

• Deploy the example

$ kubectl apply -f examples/simple-internal/
namespace/simple-internal created
deployment.apps/echoheaders created
service/echoheaders-lb-internal created

• Ensure the LB is created and the endpoint is available

$ kubectl get svc -n simple-internal
NAME                      TYPE           CLUSTER-IP     EXTERNAL-IP                                                                      PORT(S)        AGE

• Wait for the LB to be ready, then verify it is running and forwarding traffic
