Kubernetes and AX

This training is aimed at people who want to understand the basics of Kubernetes and learn how to use it to run applications with good practices.

We do not promise complete knowledge of Kubernetes in three days, but we guarantee a solid foundation and practical skills. The second part of the training is dedicated to the integration of Kubernetes with Microsoft Azure and learning about managed Kubernetes, or AKS.

The final day of the training will focus on two key aspects: using Helm Charts to install large systems and managing manifests in different environments and deployments with Kustomize.

Key Issues:

• Kubernetes Basics: Understand how Kubernetes works and how to use it.
• Best Practices in Kubernetes: Learning best practices for running applications.
• Kubernetes integration with Azure: Learn about Kubernetes integration with Azure and the functioning of AKS.
• Managed Kubernetes - AKS: Learn how to use Azure Kubernetes Service.
• Helm Charts: Create and use Helm Charts to install complex systems.
• Customise: Manage Kubernetes manifests across environments and deployments.
