In my previous article, we had an overview of secret managers, why do we need them, and some best practices on using them. A quick link if you haven’t read it yet: In real-world projects, you might use secret managers in many ways. For example, you can integrate it with your Terraform infrastructure code; you can integrate it with your configuration management tools, or CI/CD pipelines, or even in your apps, etc. And, given the rise of Kubernetes, the secret management in Kubernetes becomes more and more important, so I decided to give this specific use-case a dedicated chapter to talk about it because there are a few challenges when managing secrets in Kubernetes and different ways to integrate secret managers with Kubernetes.
