LI470: ArgoCD Best Practices NEW

Training: DevOps

The workshop provides IT professionals with practical hands-on use of GitOps with Argo CD for continuous delivery in Kubernetes environments. The objective is to manage applications declaratively with Helm, synchronize them via web interface and CLI, and deploy them to clusters in a controlled manner. USPs include cluster bootstrapping, the App-of-Apps pattern, CI integration, and practical exercises with realistic scenarios up to complex application systems.

Objectives:

After attending this workshop LI470 ArgoCD Best Practices, you will be able to:

Apply and classify GitOps core principles in Kubernetes environments
Use Helm charts for application deployment
Manage and synchronize applications declaratively with Argo CD
Administer ArgoCD via web interface and CLI
Implement cluster bootstrapping and the App-of-Apps pattern
Integrate GitOps processes into existing CI pipelines
Control typical deployment scenarios in Kubernetes securely

Target audience:

The workshop LI470 ArgoCD Best Practices is aimed at:

Administrators
DevOps Engineers
Platform Engineers
Kubernetes specialists
IT architects with a focus on cloud-native operating models

Prerequisites:

To be able to follow the content and learning pace of the workshop LI470 ArgoCD Best Practices effectively, the following prior knowledge and skills should be available:

Basic understanding of Kubernetes: Knowledge of Pods, Deployments, Services, and other basic Kubernetes resources
Familiarity with YAML: Ability to read and understand YAML files
Basic knowledge of Git: Understanding of Git repositories, commits, branches, and basic Git operations
Command-line experience: Confident use of the command line (Bash/Shell)
Container fundamentals: Understanding of container concepts and Docker
Kubernetes CLI (kubectl): Basic experience with kubectl commands is advantageous
Optionally helpful: Experience with CI/CD concepts and a basic understanding of Infrastructure as Code

Practical experience with Kubernetes is desirable, but committed participants with theoretical knowledge can also follow the workshop.

Description:

The hands-on workshop LI470 ArgoCD Best Practices provides the fundamentals and advanced concepts of GitOps with Argo CD as the central tool for continuous delivery in Kubernetes environments. At the beginning, participants learn Helm as a package manager for Kubernetes and use it for application management and deployment.

As the workshop progresses, participants deepen their use of ArgoCD through the web interface and Command Line Interface (CLI). They learn to define applications declaratively, synchronize them, and deploy them to Kubernetes clusters in a controlled manner.

In addition, the workshop covers advanced topics such as cluster bootstrapping, the App-of-Apps pattern, and integration into CI pipelines. Practical exercises based on realistic application scenarios – from simple web applications and highly available databases to more complex application systems – enable participants to apply what they have learned directly and transfer it to their own projects.
