krane
A command-line tool that helps you ship changes to a Kubernetes namespace and understand the result
If you are deploying simple manifests (not helm-stuff), try shopify's [krane](https://github.com/Shopify/krane). I build a [deploy-container](https://github.com/strowi/deploy/) for use with gitlabs ci-stages a while back.

I mean, I get that deprecating products can be annoying. But at the same time, we're talking about a for profit company. There does need to be a level of customer interest to make the maths work. Just because Red Hat doesn't have a productised version doesn't mean you can't use it though. There is always an upstream version of Red Hat products, in the case of CloudForms, that community is ManageIQ: https://www.manageiq.org

InfluxDB
Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.
