Chaos Engineering and Resilience Testing on Amazon EKS

In this article, we'll explore how to implement chaos engineering and resilience testing on Amazon Elastic Kubernetes Service (EKS). We'll cover the basics of chaos engineering, how to set up a chaos mesh, and provide a step-by-step guide on how to run a chaos experiment on EKS.

TL;DR

  • Chaos engineering is a discipline that helps you build resilient systems by introducing failures in a controlled environment.
  • We'll use Chaos Mesh, an open-source cloud-native chaos engineering platform, to set up a chaos mesh on EKS.
  • We'll run a chaos experiment on EKS to test the resilience of our system.
  • By the end of this article, you'll have a basic understanding of chaos engineering and how to implement it on EKS.

What is Chaos Engineering?

Chaos engineering is a discipline that helps you build resilient systems by introducing failures in a controlled environment. The goal of chaos engineering is to identify potential weaknesses in your system and fix them before they become major issues. By introducing failures in a controlled environment, you can test your system's ability to recover from unexpected events.

Setting up a Chaos Mesh on EKS

To set up a chaos mesh on EKS, you'll need to create a Kubernetes deployment for Chaos Mesh. You can use the following YAML configuration to create a deployment: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: chaos-mesh spec: replicas: 1 selector: matchLabels: app: chaos-mesh template: metadata: labels: app: chaos-mesh spec: containers: - name: chaos-mesh image: chaosmesh/chaos-mesh args: - --namespace=chaos-mesh ``` You can apply this configuration to your EKS cluster using the following command: ```bash kubectl apply -f chaos-mesh.yaml ```

Running a Chaos Experiment on EKS

To run a chaos experiment on EKS, you'll need to create a YAML configuration that defines the experiment. You can use the following YAML configuration as an example: ```yaml apiVersion: chaos-mesh.org/v1alpha1 kind: ChaosExperiment metadata: name: pod-kill spec: selector: matchLabels: app: my-app chaos: type: pod-kill spec: selector: matchLabels: app: my-app podSelector: matchLabels: app: my-app duration: 30s ``` You can apply this configuration to your EKS cluster using the following command: ```bash kubectl apply -f chaos-experiment.yaml ``` Once you've applied the configuration, you can run the chaos experiment using the following command: ```bash kubectl chaos run -f chaos-experiment.yaml ``` This will introduce a failure in one of the pods in your EKS cluster and test the resilience of your system.

Common Pitfalls

Here are some common pitfalls to avoid when implementing chaos engineering on EKS: *
  • Don't introduce too many failures at once. Start with small, controlled experiments and gradually increase the scope.
  • Make sure to monitor your system's behavior during the chaos experiment. This will help you identify potential weaknesses and fix them before they become major issues.
  • Don't forget to clean up after the chaos experiment. This will help prevent any unintended consequences.

Bootstrapping Kubernetes Clusters with Terraform and Argo CD: A Durable Two-Layer Approach

Bootstrapping Kubernetes Clusters with Terraform and Argo CD: A Durable Two-Layer Approach Robust cluster bootstrap separates infrastructure provisioning from continuous reconciliation. This guide details a production-grade Terraform plus Argo CD model with explicit governance. TL;DR A production-ready Kubernetes bootstrap is more reliable when Terraform and Argo CD have explicit responsibilities. Terraform should provision and manage infrastructure primitives, cluster lifecycle resources, and state safety controls. Argo CD should continuously reconcile platform and workload resources from Git using declarative application definitions. This model reduces drift and clarifies incident ownership. Teams should harden Terraform workflows with plan review and state management controls, and treat Argo CD app-of-apps repositories as privileged automation surfaces with strict access and project boundaries. App-of-apps accelerates bootstrap, but should be managed as privileged automation. Bo...

Argo CD Auto-Sync and Health Checks: An Operator's Guide to Safe GitOps Reconciliation

Argo CD Auto-Sync and Health Checks: An Operator's Guide to Safe GitOps Reconciliation Auto-sync and health are not the same thing in Argo CD. This guide shows how reconciliation, pruning, self-healing, retries, health checks, hooks, and sync waves fit together in real clusters. TL;DR Argo CD auto-sync and health checks solve different problems. Auto-sync decides when the controller reconciles Git with the cluster, while health checks decide whether the resulting resources are ready, degraded, or suspended. In practice, you need both: automated sync with prune and self-heal keeps desired state converged, retry refresh helps failed syncs recover on new revisions, and health checks plus custom Lua logic make readiness visible to operators. Sync waves and hooks add ordering when resources depend on each other. The control loop most teams misunderstand Argo CD has two separate jobs that often get blurred together in day-to-day platform talk. The first is reconciliation. Should Arg...

Kubernetes Multi-Tenancy with Namespaces and Network Policies: A Practical Guide for GitOps Teams

Image
Kubernetes Multi-Tenancy with Namespaces and Network Policies: A Practical Guide for GitOps Teams Namespaces are only the first layer of tenant isolation. This guide shows how to combine RBAC, Pod Security Admission, quotas, NetworkPolicies, and Flux service-account impersonation so teams can share a cluster without sharing blast radius. TL;DR Kubernetes multi-tenancy works only when you treat namespaces as one control in a larger isolation stack. A shared cluster needs per-tenant namespaces, namespace-scoped RBAC, Pod Security Admission labels, ResourceQuota and LimitRange defaults, and default-deny NetworkPolicies with explicit exceptions. If you use Flux CD, you also need controller lockdown and service-account impersonation so one tenant's GitOps objects cannot reach across namespaces. The practical goal is not perfect isolation from a namespace alone, but predictable blast-radius control for teams that share a cluster. A shared-cluster multi-tenancy model needs namespace bo...
