Here I would like to discuss why I consider a single-node K3s to be the best option for smaller projects. Before I proceed with this, let us define a “smaller project”. First of all, this would be a server-side project. Next, this is a project that has some back-end logic. Meaning, we are talking about… Continue reading Why K3s is the Best Option for Smaller Projects
How To Promote Software to Production with Reliza Hub
One of the most frequent questions in modern DevOps world is how to promote software from Development environment all the way to Production – via Test, UAT, Staging and other lower level environment if applicable.

Reliza CD Tutorial: Deploying on Kubernetes
This tutorial describes Reliza CD – agent that connects Kubernetes clusters to Reliza Hub and allows to deploy software from the hub.

This is no longer a secret. If you want… Continue reading On Feature Flags
Helm Chart for ECR Login on Kubernetes
Unlike other Docker registries, ECR is a bit of a pain to work with. The usual authentication process with ECR goes as following: 1. Get your IAM account with ECR permissions (pull, or push, or both) – and obtain ID and Key for this account. 2. Using AWS CLI and IAM credentials obtain login and… Continue reading Helm Chart for ECR Login on Kubernetes
