Kyverno vs. OPA Gatekeeper: My Policies, My Rules
Kubernetes is a modern marvel of orchestration - but without proper guardrails, it’s less a precision vessel and more a floating buffet for misconfigurations. With PodSecurityPolicy now consigned to the underworld (v1.25, may it rest), we’re left asking a critical question: who guards the gates of our clusters?
Enter Kyverno and OPA Gatekeeper - two policy engines, both alike in dignity, in fair Kubernetes where we lay our scene. Like Cerberus and Janus, they stand watch at the threshold: one barking at bad configs before they enter, the other scanning policy past and future in a bid for balance and order.
In this 30-minute odyssey, we’ll go beyond feature checklists to share hard-earned lessons from the chaotic beauty of production. You’ll see how these tools hold up under real-world pressure - where they shine, where they stumble, and how to make them work with your developers instead of against them. Think less red tape, more invisible shield.
If you’ve ever stared down a YAML file and thought, “Is this safe?” - This talk is your map, your Minotaur, and your exit strategy. Bring your curiosity, leave with clarity - and maybe even a few extra hours of sleep, knowing your cluster isn't standing wide open.
Beyond Dashboards: Observability in Practice
Ever wondered what really happens when you try to build an observability stack from the ground up? It’s not just dashboards and unicorns! Join Claudiu Sonel, Senior DevOps Consultant at Endava, as he shares the good, the bad, and the “why is this metric even here?” moments from his recent journey into observability on hardware devices. Get ready for real-world stories, practical lessons, and a candid look at the challenges and surprises from the front lines of infrastructure and operations.
Amazon EKS Autoscaling
Efficient resource management is vital for businesses scaling their applications in Amazon EKS. This makes autoscaling a crucial aspect of managing workloads in Amazon Elastic Kubernetes Service (EKS), ensuring optimal resource utilization and performance while keeping costs under control.
In this hands-on workshop, you'll dive into the world of autoscaling in Amazon Elastic Kubernetes Service (EKS) using a variety of powerful tools and techniques. We'll start by exploring the fundamentals of autoscaling in Kubernetes and how it integrates with Amazon EKS. You'll learn how to use Cluster Autoscaler and Horizontal Pod Autoscaler to dynamically scale your clusters and workloads based on demand.
We'll then introduce Karpenter, an open-source, high-performance Kubernetes cluster autoscaler that simplifies the scaling process with advanced features like node provisioning and efficient resource utilization. A key part of the session will include a detailed comparison between Cluster Autoscaler (CA) and Karpenter, focusing on their differences, use cases, and benefits, helping you choose the best autoscaling tool for your environment.
Additionally, you’ll gain hands-on experience with practical tools such as Terraform for automating infrastructure setup and kubectl commands to manage Kubernetes resources efficiently. By the end of this workshop, you'll be equipped with the knowledge and skills to implement autoscaling strategies in your EKS environment, optimizing both performance and cost.
What You'll Learn:
- Setting up and configuring Cluster Autoscaler and Horizontal Pod Autoscaler in Amazon EKS.
- Introduction to Karpenter and how it compares to Cluster Autoscaler.
- Automating infrastructure provisioning with Terraform.
- Managing autoscaling with kubectl commands for EKS.
- Best practices for autoscaling Kubernetes workloads in production environments.
Prerequisites:
- Basic familiarity with Kubernetes concepts and Amazon EKS.
- Experience with command-line tools like kubectl and Terraform is helpful but not required.
This workshop is ideal for DevOps engineers, Kubernetes enthusiasts, and anyone looking to optimize resource management in Amazon EKS through autoscaling. Whether you're looking to fine-tune your existing autoscaling setup or explore new ways to optimize resource usage in Amazon EKS, this workshop will equip you with the tools and knowledge to scale your infrastructure effectively.
