Implementing Canary Deployments with Flagger and Jenkins X

Deploying software updates safely in Kubernetes requires more than just standard rolling upgrades. Implementing canary releases allows you to test new versions on a small fraction of traffic before fully committing. This text-based course guides you through the foundational concepts of progressive delivery, showing you how to automate traffic shifting and metric-based analysis. You will learn to configure Flagger alongside Jenkins X to establish reliable, self-healing deployment pipelines. What you'll learn: - Understand the core principles of progressive delivery and canary deployment strategies - Configure Flagger custom resources to automate traffic shifting in Kubernetes - Integrate Jenkins X pipelines with progressive delivery workflows - Set up metric-based analysis using Prometheus to monitor canary health during rollouts - Implement automated rollbacks when performance thresholds or error rates are exceeded - Define custom routing rules using ingress controllers or service meshes You will start by exploring essential progressive delivery terminology and architectural foundations. From there, you will progress to configuring Flagger custom resource definitions, mapping out Jenkins X pipeline integrations, and setting up automated rollback policies based on real-time metrics. This course is designed for DevOps beginners, system administrators, and software engineers looking to modernize their deployment strategies. A basic understanding of Kubernetes concepts is helpful, but we start with foundational terms. Start reading today to bring automated, risk-free deployment strategies to your development lifecycle.
