Introducing Kubewarden, an Open Source Policy Engine

Security has always been a wide and complex topic. A recent survey from StackRox about the state of containers and Kubernetes security provides some interesting data on these topics. In this blog post, I’ll dive into some of the findings in that survey and introduce you to Kubewarden, an open source policy engine. A staggering 66 percent of the survey participants do not feel confident enough in the security measures they have in place.

Introduction to K3s

Whether you’re new to the cloud native space or an accomplished practitioner, you’re probably aware that there are many Kubernetes distributions to choose from. Maybe you’ve heard about the challenges of getting up and running with Kubernetes. Guess what? It doesn’t have to be hard. This blog provides an introduction to K3s, a lightweight CNCF-certified Kubernetes distribution. We’ll look at what makes K3s different from other Kubernetes distributions.

Kubernetes capacity planning: How to rightsize the requests of your cluster

Kubernetes capacity planning is one of the main challenges that infrastructure engineers have to face, as understanding Kubernetes limits and requests is not an easy thing. You might be reserving way more resources than you need to ensure your containers don’t run out of memory, or are CPU throttled. If you are in this situation, you’re going to be charged for those resources even if they aren’t being used, and it will also make deployments more difficult to schedule.

Continuous delivery with Ketch, GitHub Actions, and k3d

Can we combine the simplicity of deploying applications with Ketch with GitHub Actions and accomplish a fully automated continuous delivery pipeline? Here's what we'll do. We'll create GitHub Actions that will fully automate all the tasks starting from creating a pull request all the way until a release is deployed to production.

The rise of the developer platform

I have recently seen quite a few articles and talks covering why organizations are aiming at implementing a developer platform to help speed up the adoption of microservices within their organizations but before we get started on discussing what a developer platform is, the developer experience and productivity on Kubernetes, and how different teams are working through it, let’s define some common ground.

Digging into AWS Fargate runtime security approaches: Beyond ptrace and LD_PRELOAD

Fargate offers a great value proposition to AWS users: forget about virtual machines and just provision containers. Amazon will take care of the underlying hosts, so you will be able to focus on writing software instead of maintaining and upgrading a fleet of Linux instances. Fargate brings many benefits to the table, including small maintenance overhead, lower attack surface, and granular pricing. However, as any cloud asset, leaving your AWS Fargate tasks unattended can lead to nasty surprises.
