Granting permanent access to anyone for anything is dangerous and unnecessary. Instead, we should be using the just-in-time approach, and Apono might be just the solution for that. Enhance security, prevent breaches, and empower us to control access more effectively while easily giving temporary access to whoever needs it with Apono.

I did it. I found a replacement for the management of Kubernetes resources with Helm. I know that I said “I found a Helm replacement” quite a few times only to follow a while later with “maybe not”. I think that this time I can say “I found a Helm replacement” without changing my mind a few months later. The replacement is… Timoni backed by CUE.

What do we need to do to enable everyone to self-serve themselves when infrastructure is concerned? How can we create, operate, and destroy Kubernetes clusters without the need to involve anyone else? How can we customize the experience to fulfill the needs of our users? How can we provide a good user experience through services? How can we ensure that we are following best practices? In this video, we will explore how to create an Internal Developer Platform (IDP) for Infrastructure by combining Argo CD, Crossplane, Port, and GitHub Actions.
