  Author here. At the last two companies I've worked at we really needed—and didn't have—a solution for spinning up throwaway Kubernetes clusters that we could use for testing and development. Krucible is an attempt to solve that problem.

  We've just released a really cool feature called Snapshots that allows you to image a running Kubernetes cluster, including the state of all applications, and then create new clusters from that image. It's great for creating consistent development environments or quick starting test environments.

  Happy to answer any questions people might have.

  I have been setting up something recently using k3s (more specifically k3d for k3s in Docker) and it seems great so far. I'm having to use k3d since I'm not in Linux but as soon as WSL2 is available then I can even get rid of the Docker part I think.

  I like the idea of having a developer be able to play entirely with their own local infrastructure to get as close to production as possible.

  A hosted service will definitely make this less painful but once you get up to speed with k3s then I doubt there is anything faster than using it.

  This could be quite a handy service for throwaway cloud clusters. In the past I've used https://labs.play-with-k8s.com/ but the availability on that service has been a bit spotty of late.

  How well is this suited to use in classes? We are searching for a good way to learn students cloud stuff (asw/azure/... but also kubernetes) without high $$$

  Looks neat. May I ask what the tech stack is?

  How does this differ from Kind and Rancher k3s? The Krucible snapshot feature seems neat!
