Run CIS benchmark for KubeOne clusters #2360

Open xmudrii opened 2 years ago

xmudrii commented 2 years ago

Description of the feature you would like to add / User story

As a KubeOne user I would like that KubeOne creates clusters that adhere to the CIS security recommendations in order to have increased security of the cluster and workloads running in the cluster

Solution details

Run CIS benchmark and fix discovered issues. We already did that for KKP in the past.

Hey @dcardellino, sorry for the late reply, but we plan to work on this for the next KubeOne release (1.7).

@embik

When is this estimated to be released? (I know recently there was 1.6 but just asking :-D)

xmudrii commented 1 year ago

@dcardellino We still don't have a concrete estimation, but mostly like not before mid June.
