Ask HN: Kubernetes Deployers

What are we using to deploy to Kubernetes these days?

I have been using the same simple ruby script/gem for a long time. Honestly, I find it pretty decent, but it also feels crazy to me that there isn't something better. Don't we all need something to turn a basic description of our application into k8s yaml and give us some help with kubectl commands?

Every time I look around, I find things that feel pretty complex like https://github.com/psyhomb/k8s-deployer or they are way more than I want. I just want to say: run this command as a cron and this command as a daemon and this one as a web app. With a bit of flexibility / customizability.

Am I missing something? For reference, https://github.com/prefab-cloud/pfab is my thing. But I wouldn't say it's really fit for public consumption today.
