Kind stands for kubernetes in docker and is a tool for running a local kubernetes cluster where docker containers act as nodes. This is a great way to get started learning and using kubernetes before relying on a cloud provider. It nicely integrates with tooling, is thoroughly documented, supports mutlti-node clusters and is CNCF certified conformant kubernetes installer. We will be using Kind to deploy an application and then connecting it with a service that was deployed via docker compose. Let’s get started!

Today, we’ll be running a Python Flask app using docker. Since this app has a dependency on a database, we will deploy the application with the docker CLI and then use docker compose to run a container that contains postgres.
