Kubernetes has built-in secrets support, but there is room for improvement. Kubernetes secrets are encoded using base64, which is not secure encryption. Another limitation of Kubernetes secrets is that they can only be used inside of applications running on Kubernetes. Using Vault, we can address these concerns as well as introduce a myriad of new features. Vault is a single solution for secrets required inside Kubernetes or applications running outside of the Kubernetes cluster. Attendees will learn how to deploy and integrate Vault with Kubernetes and set up a secure solution for secret management.

Skills Gained

Attendees will understand best practices for building secure infrastructure using code, storing that code in version control, automating testing and deployment using Terraform and managing secrets with Vault.

Who Can Benefit

This class's audience is Developers, DevOps, Architects, Team Leads, Operations, and any other Engineering personnel interested in learning best practices for securing infrastructure and application code with Vault.

Prerequisites

Attendees should have a basic understanding of Linux and command-line experience.
