The container orchestration tool Kubernetes helps an increasing number of companies to automate, scale, and manage their containerized application deployments. According to the Cloud Native Computing Foundation, the open-source software foundation that hosts and maintains Kubernetes, adoption of the platform increased from seventy-eight percent in 2019 to eighty-three percent in 2020.

Last week I created a guide for our users to set up an NGINX service as an API Gateway with Qovery. The API gateway must redirect the incoming traffic to the appropriate service with the correct port. My problem is that the API Gateway does not know the ports exposed for every service. In this post, I will show you a quick tip on finding the port of a Kubernetes service with a single DNS request. Let's go!

It’s an exciting day at Sysdig as we announce our channel-first approach to doing business. What does this mean exactly?

This article explores how to secure production Kubernetes clusters with the help of open source tools. As a prerequisite, you’ll need to have basic beginner-level knowledge of Docker and Kubernetes. In a nutshell, Kubernetes is a container orchestration tool and Docker is a containerization platform. Some of the most famous Kubernetes clusters managed by cloud providers include AWS EKS, Azure AKS, and Google CKE.

As cloud-native solutions are gaining recognition and becoming a common approach to developing applications, more attention has been directed towards container orchestration and Kubernetes. Both concepts within the realm of IT have been around for a while. Thanks to the technologies' maturing and cloud adoption, they've recently gained significant attention. We all know that software containers are far from traditional shipping containers, yet they function similarly: they standardize and combine.

The Project Calico community is one of the most collaborative and supportive communities in the open-source space. Our community has shown great engagement through the years, which has helped us maintain and grow the project. Thanks to our 200+ contributors from all over the world, Calico Open Source (the solution born out of the project) is powering 1.5M+ nodes daily across 166 countries.

Last week, a critical vulnerability identified as CVE-2022-0185 was disclosed, affecting Linux kernel versions 5.1 to 5.16.1. The security vulnerability is an integer underflow in the Filesystem Context module that allows a local attacker to run arbitrary code in the context of the kernel, thus leading to privilege escalation, container environment escape, or denial of service.
