Deploy a React application to Kubernetes

Last Updated:  July 6, 2020 | Published: July 12, 2019

I've recently published my first article on dev.to about how to deploy a React application to Kubernetes in 5 easy steps.

There are many reasons for choosing Kubernetes for deploying your React application:

  • unified and standardized deployment model across the cloud providers
  • robustness against downtime as several containers are deployed (horizontal scaling)
  • handling peak traffic with auto-scaling
  • zero-downtime deployments, canary deployments, etc.
  • simple A/B testing

The tutorial will guide you through the 5 required steps for deploying the application to Kubernetes:

  • Create the React application
  • Dockerize the React application
  • Connect to your Kubernetes cluster
  • Upload the Docker image to your container registry
  • Deploy the React application

The tutorial guides you through every step and explains the minimal requirements to deploy your React application to Kubernetes.  To follow the example, you just need a Docker engine (> 18.06.0) with the local Kubernetes cluster feature enabled. For bootstrapping the React application, the CLI tool create-react-app is used. Besides that, you'll also get instructions on how to deploy the React application to a Kubernetes cluster running in the cloud.

For detailed information read the article on dev.to or have a look at my GitHub repository for the source code and a step-by-step guide.

Next, if you are looking for further tutorials on how to deploy applications to Kubernetes, take a look at this overview. Within this overview, you'll find tutorials for deploying both Jakarta EE and Spring Boot applications to a Kubernetes cluster. The Spring Boot example uses GKE (Google Kubernetes Engine) as a deployment target and you'll learn how to use a Kubernetes cluster in the cloud.

Have fun deploying your react application to Kubernetes,

Phil
