First Kubernetes App

A repository that will remind me how to create a .NET Core app, build a Docker image from it and deploy that image to Kubernetes.

Prerequisites

All

• .NET Core SDK 2.1

Mac

• Download and install Docker for Mac
• Preferences -> Kubernetes -> Enable Kubernetes

Windows

• You're on your own. Probably Docker and Minikube

Steps

Build a docker image.

docker build -t k8sfirstapp .

Run the image. This maps port 80 in the container to 8080.

docker run -p 8080:80 k8sfirstapp

Check it works by viewing in the browser. http://localhost:8080/api/random

Create the Kubernetes deployment and expose the app using a LoadBalancer service.

kubectl apply -f k8s-spec.yaml

The API should be accessible in the browser. Fingers crossed. http://localhost:4000/api/random
