Show HN: Kardinal–The lightest-weight Kubernetes dev environment in the world
Kardinal is a framework for creating lightweight ephemeral development environments in Kubernetes, supporting various testing flows. It requires specific tools and offers a playground for experimentation and extensive user support.
Read original article
Kardinal is a framework designed to facilitate the creation of lightweight ephemeral development environments within a shared Kubernetes cluster. It allows developers to create "flows," which are pathways for requests through the cluster, enabling on-demand deployment of service versions currently under development. Key features include single-service flows for testing new versions while sharing application state, multi-service flows for larger feature changes, state-isolated flows for testing database migrations, and full application flows for isolated end-to-end testing. To get started, users need to have Docker, Minikube, Kubectl, and Istio installed. Installation can be done via a simple command, and deployment of the Kardinal Manager and demo applications is straightforward. Kardinal also provides a playground in GitHub Codespaces, allowing users to experiment without installation. Comprehensive documentation, a community forum, and a blog are available to support users in effectively utilizing Kardinal.

3 commentsIn theory you could just use ingress and a special URL to deploy a single service as a special one-off deviation, but when you want to have an entire chain of services adjusted for a separate virtual environment that no longer works (unless you duplicate all services and rewrite all dependant service URLs for example).
I was expecting something like kind. This is still useful, just not what the title made me think of, though fitting everything into the title is sometimes impossible.
like the name though
