Running Kubernetes jobs from the Clojure Repl | by Kiran Karkera | Sep, 2020 | Medium

admin 2 weeks ago in

In this article, we’ll explore how to manage Kubernetes Jobs from the comfort of the Clojure Repl. A job in Kubernetes is a supervisor for batch processes, that is, a process that runs for a certain time to completion, for example, a calculation or a backup operation (source) A Job can be run once, or multiple times in parallel (e.g. to speed up computation) To…

Podman to the Rescue?. Kubernetes is overkill for so many… | by Matt Gunter | Sep, 2020 | Medium

Kubernetes is overkill for so many scenarios. The kubernetes api, on the other hand, is driving a surge of innovation by introducing important container patterns such as “pods”, “deployments”, and standardizing operational concepts like “liveness” & “readiness”. These capabilities are also being used to drive innovation in the Kubernetes (aka ‘K8s’) ecosystem. Examples include: helm, istio, calico, garden.io, Open Policy Agent (OPA), k3s, etc. All…

Introducing Kubernetes. Today, the big monolithic legacy… | by Bharat Gera | Aug, 2020 | Medium

Today, the big monolithic legacy applications are slowly being broken down into smaller, independently running components called microservices. Because microservices are decoupled from each other, they can be developed, deployed, updated, and scaled individually. But with bigger numbers of deployable components and large number of services, it becomes increasingly difficult to configure, manage, and keep the whole system running smoothly. It’s much harder to figure…

Rethinking Kubernetes Namespaces with the Hierarchical Namespace Controller -Part 1 | by John Pemberton | Sainsbury’s Tech Engineering | Aug,...

admin 1 month ago in

In this article, we’ll be taking a look at the Kubernetes Hierarchical Namespace Controller, or HNC for short. The HNC has come out of the Kubernetes Working Group for Multi-tenancy. While it’s currently incubating and not yet fit for production, it does threaten to provide some useful building blocks and paradigms for creating an easily manageable multi-tenant architecture within a kubernetes cluster. In this part…

Security of Container Technologies | by Ensar Seker | Aug, 2020 | Medium

To make matters worse, new tools and technologies, such as Dockers and Kubernetes, are coming under attack and finding their way into companies as valuable assets. These new environments are critical to ensuring that we have security-critical components of these environments. Organizations that are serious about container deployment are inevitably confronted with two critical pieces of infrastructure to manage the process: a container register and…

Passed the CKA exam on the first attempt. I like this exam because it is “hands-on”. You have to do some configurations and troubleshooting to show that you understand the concepts. How did I prepare? The main goal was to understand the inner workings of Kubernetes. Once you start understanding how everything connects and works, it becomes exciting. I used the exam to validate the…

Container Orchestration using Kubernetes (k8) — from scratch using Minikube | by Steve George | Aug, 2020 | Medium

admin 2 months ago in

Kubernetes is an open-source container-orchestration system for automating computer application deployment, scaling, and management One of the advantages of using containers is that , it can be scaled up or down depending on the demand. From a business point of view, this will ensure that change in incoming traffic can be met without much of a hardship. NOTE : From a Micro-service point of view,…

admin 2 months ago in

What is Kubernetes — Introduction to Kubernetes (K8s) Orchestration Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. Kubernetes is a powerful container management tool that automates the deployment and management of containers. It can run and coordinate containerized applications across a cluster of machines. It is a platform designed to completely manage the…
