Kubernetes testing w/ Dagger.io
What we need is a way to bootstrap a Kubernetes Cluster itself. Being in a docker-like environment the best option is a Kubernetes in Docker solution, such as KinD or K3s. Both are available in Daggerverse and can be installed as external module to be reused.

K3k: Kubernetes in Kubernetes
https://github.com/k3s-io/k3s#whats-with-the-name
> What's with the name?
> We wanted an installation of Kubernetes that was half the size in terms of memory footprint. Kubernetes is a 10 letter word stylized as k8s. So something half as big as Kubernetes would be a 5 letter word stylized as K3s. A '3' is also an '8' cut in half vertically. There is neither a long-form of K3s nor official pronunciation.
k3k is a play on k3s
but k3s is itself a play on words (k3s is supposed to be half the size of k8s, which stands for kubernetes)

Docker Compose vs Kubernetes: Secure Homelab Choices
I use K3s specifically because full Kubernetes is absurd for a homelab. K3s strips out the cloud-provider bloat and runs the control plane in a single binary. My cluster runs on a box with 32GB RAM — plenty for ~40 pods.

Stop babysitting your AI agent!
NVIDIA seems to agree. Their OpenShell project takes the same approach: sandboxed execution environments with declarative YAML policies governing egress, filesystem access, and credentials. It uses containers (K3s under the hood) as the isolation boundary.
