/ Course Details & Curriculum
Welcome to Argo CD and Argo Rollouts for GitOps: The Definitive Guide! Are you ready to modernize your Kubernetes deployments and adopt the industry standard for Continuous Delivery? This course is designed to take you from a GitOps novice to an expert practitioner, equipping you with a deep, practical understanding of Argo CD and Argo Rollouts.
Why Learn Argo CD and Argo Rollouts?
The Kubernetes ecosystem has shifted. The traditional "push-based" deployment models are being replaced by GitOps, and basic Kubernetes Deployments are no longer enough for mission-critical applications. Here is why mastering these tools is essential:
- Master the GitOps Standard: GitOps is the modern operating model for cloud-native applications. Argo CD is the leading tool in this space, enabling you to use Git as the "single source of truth" for your infrastructure. Learning this allows you to automate synchronization, detect configuration drift, and ensure your clusters always match your desired state.
- Move Beyond Basic Deployments: Standard Kubernetes rolling updates have limitations: they are often "all or nothing." Argo Rollouts empowers you to perform advanced progressive delivery strategies like Blue-Green and Canary deployments, giving you granular control over traffic and the safety of your releases.
- Enhance Cluster Security and Stability: By using the "Pull Model" with Argo CD, you stop exposing your cluster credentials to external CI systems. By using Argo Rollouts with automated analysis, you prevent bugs from reaching 100% of your users. These are critical skills for any Senior DevOps Engineer or SRE.
- High Market Demand: Companies are rapidly adopting the Argo project suite to manage complex microservices architectures. Proficiency in Argo CD and Argo Rollouts will make you a standout candidate in the tech job market, opening doors to advanced infrastructure roles.
By investing time in this course, you are future-proofing your tech profile and learning how to build self-healing, automated, and secure delivery pipelines.
Why Should You Choose This Course?
This course offers a unique blend of deep theoretical dives and extensive practical application. We don't just skim the surface; we configure advanced scenarios that mirror real-world production environments.
- Learn by Doing with Extensive Labs: I believe that you only truly learn by getting your hands dirty. Every section of this course includes dedicated hands-on labs where you will install, configure, and debug real scenarios. I provide the tasks, allow you to try them, and then walk you through the solution step-by-step.
- Focus on Real-World Patterns: We don't just deploy "Hello World" apps. We tackle real challenges: connecting to private Git repositories via SSH and HTTPS, managing Helm charts with custom values, setting up multi-tenancy with Projects, and configuring self-healing capabilities.
- Advanced Traffic Management: You will learn how to implement traffic-weighted canary releases using the Kubernetes Gateway API and Traefik, moving beyond the limitations of simple replica-weighted traffic splitting.
- Automated Metrics Analysis: You will learn how to integrate Prometheus to enable fully automated progressive delivery. You will build analyses that query metrics in real-time and automatically promote or rollback releases based on success rates—true "set it and forget it" automation.
- Expert Guidance: I strip away the complexity of the CNCF landscape and focus on what matters. I will teach you not just how to configure a YAML file, but why it works that way, how to debug it when it breaks, and the best practices for production usage.
Which Skills Will You Acquire During This Course?
As you progress through the lectures and labs, you will gain a comprehensive set of skills, including:
- Implementing the GitOps Workflow: You will learn to decouple Continuous Integration (CI) from Continuous Delivery (CD), using Argo CD to automatically sync, prune, and self-heal your applications based on Git commit history.
- Managing Applications at Scale: You will master the Application Custom Resource Definition (CRD), deploy applications using Helm Charts, override chart values dynamically, and utilize Sync Waves and Hooks to orchestrate complex deployment dependencies (like database migrations).
- Securing and Organizing Argo CD: You will learn to manage Projects to enforce RBAC (Role-Based Access Control), restrict deployment targets, and securely connect to private repositories using secrets.
- Executing Blue-Green Deployments: You will use Argo Rollouts to spin up parallel environments, verify new versions before they take live traffic, and switch traffic instantaneously.
- Mastering Canary Releases: You will move beyond simple Kubernetes Deployments by implementing Canary strategies. You will learn to pause rollouts, use manual promotion steps, and implement header-based routing for specific testing by QA teams.
- Advanced Gateway API Integration: You will configure Traefik as a Gateway Controller and use the Argo Rollouts Gateway API Plugin to achieve precise, percentage-based traffic splitting rather than relying on rough replica counts.
- Automated Analysis and Rollbacks: You will integrate Prometheus to scrape application metrics and configure Argo Rollouts to query these metrics during updates. If an error rate spikes, you will watch the system automatically abort the rollout and restore the stable version without human intervention.
Get ready to master the tools that are defining the future of Kubernetes deployments. Let's start this exciting journey into Argo CD and Argo Rollouts together!
