Agent that audits my Kubernetes cluster for best practices

Agent that audits and monitors my Kubernetes cluster

• Best practice configs - is my cluster set up with optimal configs for my needs? identify and fix gaps

• AWS charges “extended support” premium on older Kubernetes versions, even if that is considered the stable release. As a result it becomes really easy to rack up extra charges. I want an agent that can monitor this for me (and ideally run update - with the team in the loop)
