KubeCluster Docs Typo

[chriscardillo]

Describe the issue: Latest docs for using the KubeCluster class uses a name that is not a "a lowercase RFC 1123 subdomain", which cases a 403 error when ran in a Kubernetes cluster.

Minimal Complete Verifiable Example: Run the latest docs example:

from dask_kubernetes.operator import KubeCluster
cluster = KubeCluster(name="my_dask_cluster", image='ghcr.io/dask/dask:latest')

Anything else we need to know?: my-dask-cluster will work as an alternative.

Environment:

• Dask version: dask==2023.3.0, dask-kubernetes==2023.1.1
• Python version: 3.9.14
• Operating System: Debian GNU/Linux 11 (bullseye)
• Install method (conda, pip, source): pip
• Kubernetes version: 1.25.3

Thanks for raising this. I see two issues here:

• Our docs have an invalid name
• We are not doing any input validation on the name

It would be good to address both of those problems.

Closed the immediate bug in #681 and opened #682 to track future work around input sanitising.
