Getting Started With Container Registries

Container registries serve as libraries to store and access third-party container images required during the build phase of the SDLC and the images produced for deployment to test, staging, and production environments. While public container registries are accessible and convenient, private registries can better integrate into existing CI/CD workflows, offer greater control over access and security, as well as help ensure build repeatability and reliability. This Refcard covers key container concepts and terminology; common use cases; and guidelines for container registry configuration, operation, security, and storage.

How to Use the Open Source Tool Traefik to Direct Kubernetes Traffic

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.
