Deploy a Flask Application to a Google Kubernetes Engine

Kubernetes is an open-source platform that lets us deploy and manage containerized applications. Kubernetes manages services from the deployment stage to the final stage of exposure. Through plugins, Kubernetes also provides other services like auto-scaling, availability, and fault tolerance.

Helm is a package manager for Kubernetes. It bundles a couple of Kubernetes resource files into a single package, known as a Helm chart, which can be easily deployed. A single command is enough to deploy a distributed application packaged through the Helm. Helm packages applications with a default configuration that can be modified later.

In this project, we’ll start by using Docker to containerize our Flask application and push the image to Docker Hub. After this, we’ll create a Google Cloud project. Later on, we’ll also set up Google Cloud CLI and Helm. We’ll then proceed to create a Kubernetes cluster and our own Helm chart. After we configure this chart, we’ll finally deploy it and access our application.
