Kubevious: Kubernetes Dashboard That Isn’t A Waste Of Time

After many failed attempts to find a Kubernetes dashboard that is actually useful (even a little bit), I finally stumbled upon Kubevious. There is finally a Kubernetes UI I can recommend.

Argo CD: Applying GitOps Principles To Manage Production Environment In Kubernetes

Argo CD is a declarative GitOps deployment tool for Kubernetes.

It is one of the best, if not the best tool we have today to deploy applications inside Kubernetes clusters. It is based on GitOps principles, and it is a perfect fit to be a part of continuous delivery pipelines. It provides all the building blocks we might need if we would like to adopt GitOps principles for deployments and inject them inside the process of application lifecycle management.

Argo CD is a tool that helps us forget the existence of kubectl apply, helm install, and similar commands. It is a mechanism that allows us to focus on defining the desired state of our environments and pushing definitions to Git. It is up to Argo CD to figure out how to converge our desires into reality.

Serverless Computing With Knative And Containers As A Service (CaaS)

This text was taken from the book and a Udemy course The DevOps Toolkit: Catalog, Patterns, And Blueprints

All the commands from this article are in the [04-03-knative.sh](Gist with the commands: https://gist.github.com/dc4ba562328c1d088047884026371f1f) Gist.

Before we dive into the actual usage of Knative, let's see which components we got and how they interact with each other. We'll approach the subject by trying to figure out the flow of a request. It starts with a user.

Choosing The Right Deployment Strategy

Deployment strategies affect everyone, no matter whether we are focused only on a single aspect of the application lifecycle or we are in full control. The way we deploy affects the architecture, testing, monitoring, and many other aspects. And not only that, but we can say that architecture, testing, and monitoring affect the way we deploy. All those things are closely related and affect each other.

We'll discuss different deployment strategies and answer a couple of questions. Is your application stateful or stateless? Does its architecture permit scaling? How do you roll back? How do you scale up and down? Do you need your application to run always? Should you use Kubernetes Deployments instead of, let's say, StatefulSets? Answers to those questions will not serve much unless we are familiar with some of the most commonly used deployment strategies. Not only that knowledge will help us choose which one to pick, but they might even influence the architecture of our applications.
