Most applications depend on external factors that have different values depending on the environment where they are deployed. We mostly use for that environment variables. Guess what? Most of React Apps also have this need. In this blog posts presents a clean(er) way to make a multi-stage deployment of a Create React App on a Kubernetes Cluster. You can use this approach for a seamless integration into your continuous deployment pipeline.

In the beginning it will you show how to set up the React App and then guide you through several deployment possibilities on Kubernetes. You will deploy with native kubectl commands, with helm, with kustomize and in the end use skaffold.

The example app displays the latest public bookmarks published on www.bookmarks.dev. Depending on the environment the app is built for, it will display the environment name in the navigation bar and the header’s color is different.

The source code is available on Github

TLDR;

Create a config.js file where you inject the environment variables in the window object (e.g. window.REACT_APP_API_URL=’https://www.bookmarks.dev/api/public/bookmarks’). Add this file to the public folder of your react application. Dockerize the react application and at Kubernetes deployment time overwrite the config.js file in the container - you can do that with Kubernetes configMaps via native kubectl commands, kustomize or helm.

We have recently reached a second major milestone on www.bookmarks.dev. There are now more than 10k curated public dev bookmarks available. To be more precise there are exactly 11869 public dev bookmarks at the time of this writing . You can find there programming resources for languages like java, javascript, go, python to query languages sql, graphql, to free-programming-books but also “exotic” stuff like genetic-algorithms and astronomy.

All of these dev resources are personally curated or by the users who submitted them - thank you very much for your contributions. The rest are imported from the Awesome collections.

Motivation

Finding the desired link again can be sometimes a tedious job. It can even become frustrating when you don’t find it in a reasonable amount of time, because you know it’s there somewhere, you visited it before… After a struggle of about two or more minutes you finally find it.

Nailed it

This time you bookmark it and then you say to yourself - “from now on I will be more disciplined and consciously use bookmarks”.

bookmark (verb) - record the address of (a website, file, etc.) to enable quick access in future.

So far, so good. The problem is your bookmarks can turn into a monster themselves and you can later lose then more time browsing through them to find the right one, because you know now you bookmarked it…
