So what is it?

This repository, vcluster-values, provides configuration files for vCluster, a tool that creates lightweight, isolated Kubernetes environments inside existing Kubernetes clusters. In plain terms, it lets teams spin up separate "mini-clusters" that act like their own independent Kubernetes setups, without needing to carve out dedicated hardware or get administrator approval each time. The repo itself contains the "values definition", essentially the default settings and templates that tell vCluster how to configure these virtual clusters when they're created. Think of it as the recipe or blueprint the tool follows so that every virtual cluster comes out consistent and correctly set up. It's written in Go, which is the same language the broader vCluster project uses. The people who'd use this are typically platform engineers or DevOps folks at companies that already run Kubernetes and want to give developers their own self-serve environments. For example, a startup with five engineering squads could let each squad spin up and tear down its own isolated cluster for testing, without anyone stepping on each other's work or bothering the infrastructure team. It's also handy for CI pipelines that need a fresh, throwaway cluster for each test run. The README doesn't go into further detail about specific configuration options or advanced usage. Those interested in how the values are structured would need to look at the files directly or consult the main vCluster documentation for the bigger picture.

Copy-paste prompts

Prompt 1
How do I use the values definition files in vcluster-values to configure a new virtual cluster in my existing Kubernetes setup?
Prompt 2
Show me how to spin up an isolated vCluster for CI testing using the default values from vcluster-values and then tear it down after the run.
Prompt 3
What configuration options does vcluster-values expose, and how do I customize them for my team's mini-cluster?
Prompt 4
Help me set up vCluster so multiple engineering squads can self-serve their own isolated clusters without needing admin approval each time.
