Can Kubernetes Keep a Secret? It All Depends What Tool You’re Using

Can Kubernetes Keep a Secret? It all depends what tool you’re using

At Soluto, we have super-devs who have full ownership: from writing code to deploying it to monitoring. When we made the shift to Kubernetes, we wanted to keep our devs independent and put a lot of effort into allowing them to create services rapidly. It all worked like a charm – until they had to handle credentials.

This challenge leads us to build Kamus – an open source, GitOps, zero trust, secrets solution for Kubernetes applications. Kamus allows you to seamlessly encrypt secret values and commit them to source control. But before diving into how Kamus works, let’s do a quick recap of Kubernetes native secrets solution, and why we even need Kamus.

As you may already know, Kubernetes has a built-in object for secret management, with the super surprising name “Secret”. A Kubernetes secret is a simple object that’s stored securely (e.g. encrypted at rest) by the orchestrator, and can contain arbitrary data in key-value format. Here’s an example of what a Kubernetes secret looks like:
