Building and launching a simple application on Minikube

Let's take our first steps to building a simple application on our local minikube cluster and getting it to run.

The first thing we need to do is build a container image for our application. The simplest way to do this is to create a Dockerfile and use the docker build command.

Use your favorite text editor to create a file called Dockerfile with the following content:

Dockerfile 
FROM nginx:alpine 
RUN echo "<h1>Hello World</h1>" > /usr/share/nginx/html/index.html 

To build the application, first ensure your Docker client is pointing to the Docker instance inside the Minikube VM by running:

    eval $(minikube docker-env)

Then use Docker to build the image. In this case, we are tagging the image hello, but you could use any tag you wanted:

    docker build -t hello:v1 .
