It describes the tested Linux and Ubuntu environment, notes that the commands should work similarly on macOS, and discusses extracting client certificates from a Kubeconfig file for certificate-based authentication. ### Source excerpt When I first started learning Kubernetes, I had the idea that observing the network traffic between a client system using kubectl and the Kubernetes API Server would be a useful thing to do. The source of the idea is unclear; I am unsure why I thought this would be useful as a learning tool. Regardless, I continued on with learning Kubernetes and never really pursued this idea--until this week. I found it can be a useful troubleshooting technique, but I will leave it up to you to determine if it is a useful learning technique. In this post, I will show you how to observe kubectl traffic using mitmproxy. This technique is inspired by/informed by Ahmet Alp Balkan's similarly-named blog post from 2019. Unfortunately, I found the instructions there to be incomplete (most likely just due to the passage of time and continued evolution of the tools involved). I used the following tools and environments in my testing: The tests were conducted on a Linux system running Ubuntu 24.04.4. The commands should work similarly on macOS. Mitmproxy was installed from the Ubuntu repositories using apt. kubectl version 1.33.3 was used to communicate to a self-managed cluster on AWS (in other words, not Amazon EKS) running Kubernetes 1.32.9. The cluster was bootstrapped using kubeadm. I wouldn't expect any major/significant differences with other versions of kubectl or Kubernetes. I was using a client certificate to authenticate to Kubernetes. It's unclear to me how this might work--if it works at all--with alternate authentication mechanisms. Prepare Client Certificates Before you can start mitmproxy, you'll first need to extract the client certificates from the Kubeconfig file. A couple of ways exist to do this; a blog post of mine from 2022 contains what I believe is the easiest way. The method involves yq (to extract information from the Kubeconfig) and base64 (to decode the client certificate and client key). Refer to the linked blog post for full details. First, extract the client cer ## Blog: Detecting Threats in OVHcloud MKS Audit Logs with Falco DevFeed: [Blog: Detecting Threats in OVHcloud MKS Audit Logs with Falco]() Original publisher: [Read original article]() Published: 2025-03-13T00:00:00Z Content type: tutorial Language: en Sources: [Falco - Falco](), [Falco - The Falco blog]() Topics: [Kubernetes](), [Security](), [threat detection](), [Kubernetes clusters](), [kubectl](), [Cloud](), [Open Source](), [api server](), [container](), [Amazon EKS](), [Amazon Elastic Kubernetes Service]() Tags: [api](), [audit](), [auditlogs](), [container](), [falco](), [kubectl](), [kubernetes](), [linux](), [logs](), [mks](), [ovhcloud](), [plugin](), [security](), [threat-detection]() ### AI overview This article explains how Falco uses the OVHcloud MKS Audit Logs plugin to detect anomalies, suspicious activity, and policy violations in Kubernetes clusters. It describes Falco's event processing and outlines the required setup involving OVHcloud Logs Data Platform, a data stream, and an MKS cluster. ### Source excerpt Detecting threats in a Kubernetes cluster can be challenging, we generally don't know where and how to start. The good news is that we have an amount of valuable logs that can help us to know what is happened in the cluster. Indeed, each action requested or done by a user or an app, in a cluster, is recorded in Audit Logs. Kubernetes events are key to understanding the behavior of a cluster. We already provide plugins that let you parse Audit Logs and use Falco to detect threats from GKE, EKS and AKS clusters. With our latest plugin, you'll now have the same powerful threat detection capabilities for your OVHcloud MKS clusters 🎉. What is Falco? Falco is an Open Source cloud-native runtime security tool. It provides near real-time threat detection for cloud, container, and Kubernetes workloads by leveraging runtime insights. Falco can monitor events from various sources, including the Linux kernel, and enrich them with metadata from the Kubernetes API server, container runtime, and more. Falco can receive Events, compare them to a set of Rules to determine the actions to perform and generate Alerts to different endpoints. What is the OVH MKS Audit Logs plugin? The OVH audit logs plugin (k8saudit-ovh) extends Falco's capabilities to OVHcloud Managed Kubernetes Service (MKS) clusters, providing you with the same security insights and threat detection Falco already offers for GKE, EKS and AKS environments. With this plugin, you can seamlessly integrate MKS Audit Logs into Falco's event processing pipeline, enabling it to identify anomalies, suspicious activities, and policy violations within your MKS-based workloads. Concretely, when a user executes some kubectl commands in an OVHcloud MKS cluster, Audit Logs will be generated. Falco is listening to them, and depending on the configured rules to follow, it will generate some alerts. Using OVH MKS Audit Logs plugin In order to use the OVH MKS Audit Logs plugin, you must follow several steps: deploy an OVHcloud LDP (Logs ## Automating Keycloak Deployments for Fun and Profit DevFeed: [Automating Keycloak Deployments for Fun and Profit]() Original publisher: [Read original article]() Author: brakmic Published: 2024-12-24T22:31:29Z Content type: tutorial Language: en Sources: [Harris Brakmic - Coding]() Topics: [Deployment](), [Kubernetes](), [Helm charts](), [Docker](), [DevOps](), [Testing](), [PostgreSQL](), [sealed secrets](), [kubectl](), [Debian]() Tags: [bash](), [build](), [coding](), [debian](), [deployment](), [devops](), [docker](), [examples](), [ha](), [helm](), [helm-charts](), [high-availability](), [iam](), [java](), [keycloak](), [kubectl](), [kubernetes](), [nginx](), [postgresql](), [sealed-secrets](), [testing]() ### AI overview A practical tutorial for automating a local Keycloak deployment designed to resemble a production environment.
