If you’re reading this article, you’re probably either running a Kubernetes cluster or planning to run one. Whatever the case may be, you will most likely need to have a look at data—how to store it and how to secure it. There are different types of stored data in Kubernetes: In this article, we will review how to deal with each of these data types in a Kubernetes cluster.

Though Kubernetes has grown in popularity, it still has a steep learning curve that can make it hard to adopt the technology. Those who can’t get past this initial hurdle are often left behind in the fast-paced field of software development. This article will introduce YAML files for Kubernetes object configuration. YAML provides a way to declaratively configure your Kubernetes applications, and these declarative files allow you to effectively scale and manage your applications.

At the core of Kubernetes is the notion of high availability, meaning that every part of the system is redundant so it can continue to function despite failures. This includes multiple worker nodes to run your workload, apps are written to be able to run as multiple pods, and even the control plane will work across a cluster of machines. In this article, we’ll explain the different ways to manage network traffic in the Kubernetes cluster.

Researcher Moshe Zioni from Apiiro, discovered a major software supply chain critical vulnerability - CVE-2022-24348 - in the popular open-source CD platform Argo CD. Exploiting it enables attackers to obtain sensitive information like credentials, secrets, API keys from other applications. This in turn can lead to privilege escalation, lateral movements, and information disclosure.
