Hi everyone ‍️,

Let me introduce you Knative, a friend (or extension) of Kubernetes , an easy way to stop apps when not used and so, save our planet from CO₂ attack!

Works out of the box for a Docker/OCI image of a serving app (like a REST app), but needs some changes for event consumers one’s.

As the app starts on first request, is better to have a rabbit startup performance level degree than a tortoise’s one (only works in this case ). In Java ️ apps, native-images comes to rescue (more about that in the next post).

You can see a working example of Knative serving a native java REST app in this interactive Katacoda tutorial, or if you are a lucky French speaker, you can simply watch this demo video: .

Cheers
