This tutorial shows you how to run a sample app on Kubernetes using minikube. The tutorial provides a container image that uses NGINX to echo back all the requests. Objectives Deploy a sample application to minikube. Run the app. View application logs. Before you begin This tutorial assumes that you have already set up minikube. See Step 1 in minikube start for installation instructions. Note:Only execute the instructions in Step 1, Installation.

This page shows how to create an external load balancer. When creating a Service, you have the option of automatically creating a cloud load balancer. This provides an externally-accessible IP address that sends traffic to the correct port on your cluster nodes, provided your cluster runs in a supported environment and is configured with the correct cloud load balancer provider package. You can also use an Ingress in place of Service.

This page shows how to use kubectl port-forward to connect to a MongoDB server running in a Kubernetes cluster. This type of connection can be useful for database debugging.
