Might I suggest a Helm chart so that people can just apply it/install it to their home test k8s cluster, etc.
For single node installations, you can use base k8s manifests that is available using instructions at - https://openobserve.ai/docs/quickstart/#self-hosted-installa... .
Mike created a helm chart for s ingle node installation too - https://github.com/mshade/openobserve-chart/
