Demo of CUE and k8s

Summary

This demo aims to showcase some of the features of CUE and how they can improve the life of a kubernetes administrator.

Cue

First set the working dir. This should be the root of the git repo!

export WDIR=$(pwd)

Enable the experimental cue modules support.

export CUE_EXPERIMENT=modules

Set the OCI registry URL.

export CUE_REGISTRY=localhost:5000/cue

Registry

Pull and run a docker registry.

docker run -d -p 5000:5000 --restart always --name registry registry:2

Destroy registry to cleanup.

docker rm -f registry

Cue Modules

Upload supporting modules to the OCI registry. These modules are utilized by apps, bundles, flavors and cluster configurations. They are mostly schemas and therefor are very generalized.
