OpenFaaS VS Dokku

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.

OpenFaaS

Anyone knows other alternatives for Azure Functions, but for DIY hosting? ( eg. OpenFaas - https://www.openfaas.com/ )

This is where I see K8S coming in – teachers can provide dev deployments that are setup for students to learn. Teachers can also provide containers that run automated tests against the student containers for assessment! Plus, we can smooth over some of the git workflow stuff for the ripest of beginners; we can integrate with github to sync their work on our platform to repositories on their github account, so that they can really take ownership of the work they do on the platform. Last, students can graduate their work from development into production very easily, since we can take the base images + student diffs, build a new "prod" image for the student. We can run students' prod work on "serverless" K8S frameworks like fission or OpenFaas to be able to host many low-traffic "production" apps at the same time.

OpenFAAS or FN Project are options

Closest thing I can think of is https://www.openfaas.com (which runs on top of K8s).

OpenFaaS for the serverless functions

If you want to look into FaaS in selfhosted ways, take a look at OpenFaaS, which nowadays works on Kubernetes though - https://www.openfaas.com/. Note that the CE version of OpenFaaS only includes some basic autoscaling. For more complex solutions check out their paid version.

I run all my projects on Dokku. It’s a sweet spot for me between a barebones VPS with Docker Compose and something a lot more complicated like k8s. Dokku comes with a bunch of solid plugins for databases that handle backups and such. Zero downtime deploys, TLS cert management, reverse proxies, all out of the box. It’s simple enough to understand in a weekend and has been quietly maintained for many years. The only downside is it’s meant mostly for single server deployments, but I’ve never needed another server so far.

Yeah there are a bunch of selfhostable things:

Caprover (https://caprover.com/)

Dokku (https://github.com/dokku/dokku)

But people still choose Netlify and Vercel for ease of use I think.

Maybe we need something that's just Netlify. The closest I've seen to the "right" UX is Ness:

The modern iteration of these tools has taken the developer experience learnings from the Platform as a Service (PaaS) category, and will bring them to your own VM, giving you your own personal PaaS. Example of this include Dokku, Coolify, Caprover, Cloud66 and many more!

Based on the fact that your ideal is to have a similar experience to heroku than managing your own server setting up reverse proxies take a look at these options:

1) https://dokku.com - lets you turn your light sail instance basically into heroku

2) https://render.com

3) https://fly.io

4) If you have aws credits this is their heroku equivalent: https://aws.amazon.com/elasticbeanstalk

above is not what I do but would be the options I would pursue if I understand your preference and requirement correctly.

All in all, I really recommend trying out Dokku if you are a developer interested in hosting your own projects. It makes it super easy to get everything you need to get up and running without having to worry about the specifics. And the price is impossible to beat!

The installation instructions are on the frontpage of our site. Thats basically all you need to do to install Dokku. As far as using it, we have a simplified tutorial here.

Dokku is a lightweight and open-source PaaS platform that simplifies application deployment by leveraging Docker. With Dokku, developers can easily push their applications using Git, allowing Dokku to build and run them in isolated containers. Its CLI-only approach and plugin architecture make it highly extensible. Dokku's modular plugins enable features like database integration, Let's Encrypt SSL certificates, and automated Slack notifications, giving developers flexibility and control over their PaaS environment.

This is a great tool if you want PaaS like UX but just want to run Rails on a single VM https://dokku.com/
