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, for example, easily and reliably test our deployment process in. Kind (
https://github.com/kubernetes-sigs/kind) does a pretty good job of addressing that but requires setting up a bunch of infrastructure that needs to be maintained and doesn't easily work in a containerised CI environment. Krucible is an attempt at solving those problems by allowing you to spin up Kubernetes clusters via an API quickly and affordably.
Krucible is still in its early stages but I wanted to show it to the community and get feedback. Happy to answer any questions.
