docs VS kubero

I could provide a big overview of how Knative works, but in this little tutorial I want to show you the basic installation and configuration and how to deploy your first Knative service.

Serverless functions are now offered by many cloud providers, as well as having options like OpenFaaS, Knative, Apache's Openwhisk and more from the open source community that run in environments ranging from one server all the way up to globally replicated private clusters.

The usual product I see for serverless on Kubernetes is Knative: https://knative.dev/docs/

For deploying your apps you could use something like Kubero (https://github.com/kubero-dev/kubero)

Are you running Kubero in the background? Zeabur seems to have the same feature set, and Add-ons.

However, because I want to offer an MTA as an add-on for Kubero, my Heroku alternative, I have decided to create one with Haraka. Haraka is a well-known MTA and is used by Craigslist. This MTA is very flexible and can be extended with plugins. It is also highly performant and can run on minimal resources. Another important criterion is that it has been well maintained and developed for a long time.

I'm the maintainer of Kubero, which is pretty similar but requires a Kubernetes cluster, which might be a show-stopper in your case. But apart from that, Kubero would be able to fulfill your requirements:

Probably kubero

I'm self-hosting Heroku with Kubero.
