First off, happy new year!
After facing a few patches of public registry downtime at the end of the year (both Docker Hub and ECR), one of our first goals of 2022 was to implement pull-through caching of public images. This would allow Shipyard users to continue building, testing, and reviewing their applications, even when outages happen.
The following code is a sample Node server implemented with the Express.js framework. Tests for the app are written through the Mocha framework.
In this article, we will build and test the code with npm (suggested GitHub workflow). Once all the tests pass, build the Docker image, push it into the Docker hub, and use GitHub secrets to store the credentials.
This tutorial will show you how to ingress traffic from external sources into a Kubernetes-Raspberry Pi cluster by using the open-source cloud-native edge router, Traefik. I’ll then detail how you can clean up Kubernetes resources afterward.
First things first, you’ll need a k3s Raspberry Pi cluster like the one I've detailed here. Your cluster will also need internet connectivity in order to access online images. All of the sample configuration and HTML files used below are available for download from GitLab.
