Kubernetes 101 - Happy Panda App

A simple Happy Panda html page.

Getting Started

You need the following software:

• Git
• Kubectl
• Kubernetes on Docker
• Make

Docker for troubleshooting

You might want to run a container on docker with a volume dynamically mounted due to troubleshooting purposes, to do so you can run the following docker command:

docker run --name <container_name> -v $PWD/src:/usr/share/nginx/html:ro -d -p 8080:80 nginx

Then http://localhost:8080

Now you can modify the code within src folder and check it out instantly in your browser.

Clean up

docker stop <container_name>

docker rm <container_name>

Kubernetes

Everything can be checked on this URL:
