faasd

I'm the original creator of faasd, and just found this post on the Internet. What I liked was how he discovered faasd and found some unique value in it. I wanted to share it all with a broader audience here. His bootstrap is a little bit convoluted, if you check out GitHub, we have a simple installer script and an eBook as a reference manual. I'm not sure what the author means when he says it's complicated, but installing faasd requires almost no knowledge of containers, and there are very detailed step-by-step instructions. Once it's up and running, it's pretty much the same experience as openfaas on Kubernetes, just without scaling and clustering. https://github.com/openfaas/faasd

I didn't write this blog post, but helped Carlos with some editing. It was great chatting to him about how he planned it out and got it up and running in a short period of time. If you're wanting to keep your infrastructure lean, you can use OpenFaaS on a single VM with "faasd" instead of K3s/K8s. https://github.com/openfaas/faasd

Maybe you should give OpenFaas a spin. You can run it completely locally on your machine with Docker . It's mostly based off of Kubernetes. But you can also test it on EC2 or any virtual machine using faasd. https://docs.openfaas.com/ https://github.com/openfaas/faasd

I was just reading the beginning of Arvid Kahl's Zero to Sold. He recommends using a tech stack that you already know and have lots of muscle memory with. I couldn't agree with him more. [1] This tech stack looks over-engineered upon first glance, but I don't know much about the author or his product. I use Kubernetes a fair bit whilst developing OpenFaaS and teaching people about K3s, but there is a whole world of development teams who aren't prepared to consider it as an option. One of the reasons we created "faasd" [2] (single-node OpenFaaS) was to help people who just wanted to run some code, but didn't want to take "Kubernetes mastery 101" For a small app using a managed service like Cloud Run plus some cloud storage should get you very far. I saw that Heroku is still popular with the indie community, with the author of Bannerbear ge

There's faasd [https://github.com/openfaas/faasd] which is OpenFaaS without the Kubernetes overhead.

I was joined by Taylor Dolezal for this live stream and was surprised to learn that Taylor has not only tried OpenFaaS before, but used it in two jobs - including at Disney. After the intro, we talk a bit about Go features like testing and newer features like generics, before going into a bit of a deep dive coding session, building up functions from scratch in Golang. The functions built with OpenFaaS are actually containers with a HTTP server inside, so they can be deployed to Kubernetes, Cloud Run or Knative in a similar way. They would probably also work with fly (but I haven't tried that yet) The "workload" definition is HTTP on port 8080 and a health check (configurable) https://docs.openfaas.com/reference/workloads/ For folks starting out with FaaS and not ready to go full-on K8s, faasd might be a good option to explore - https://gi

Disclaimer, I am a CNCF Ambassador (voluntary) - so it's in my interest to promote CNCF projects like Kubernetes. It seems like a good time to mention my blog post from last year "Then he asked me “Is Kubernetes right for us?" -> https://alexellisuk.medium.com/then-he-asked-me-is-kubernete... Some of the feedback I've had so far is that it was refreshing to get "permission" to consider alternatives vs. the current hype. I use K8s and K3s quite broadly myself, but increasingly see consulting prospects and customers who are not comfortable to make the leap, but are very happy on managed services with their chosen vendor - Azure / AWS / GCP. GitLab recently released a bunch of terraform to show you how to run side projects in the free tier of a cloud - https://gitlab.com/gitlab-org/5-minute-production-app/deploy... The OpenFaaS project again

Yes, I talk about my RPi builds in this guide - https://blog.alexellis.io/self-hosting-kubernetes-on-your-ra... I do like to always have 1-2 Intel NUC headless Linux boxes for running containers and K8s. I run my sponsors portal using an RPi3 and an inlets tunnel. The microservices are served with faasd - it gets light traffic, but is basically free. http://github.com/openfaas/faasd

The latest addition here is to show how to capture screenshots from locally rendered HTML/CSS - perfect for social banners. Sites like Banner bear (no affiliation) are charging a fee for this kind of function, and all the better for it. Folks should charge for their work. But if you are comfortable hosting openfaas (3 EUR / mo on Hetzner using faasd) then you can do it a lot cheaper and run additional webhooks / APIs / blogs / integrations there too. A banner generation website will cost 49 USD / mo for 1000 images, 99 USD / mo for 10,000 images. Or 3 EUR / mo for faasd. https://github.com/openfaas/faasd

Alex, OpenFaaS founder here. The author has done a huge amount of work here, I am surprised that it's being given away for free, and not being monetized (it should be). I often hear folks complain that Kubernetes is complex, and hard to understand. We've done a lot of work to make the experience of deploying functions simple on K8s, with very little to manage. But it still costs you a K8s cluster - most of our users don't mind that, because they have one anyway. But, for everyone else we created a new of openfaas called "faasd" which can run very well somewhere like DO or Hetzner for 3 EUR / mo. It doesn't include clustering, but is likely to be suitable for a lot of folks, who don't want to get deep into IAM territory. https://github.com/openfaas/faasd The REST API for OpenFaaS has a terraform provider that works with either version - ht

K3s needs 500MB of RAM on a server and 50MB on an agent. That's the lowest we've ever seen for Kubernetes and Darren is planning on getting something working on 256MB SoC devices next. If you want to go ultra-lean, and only need a single node RPi or VPS (many applications don't need massive scale-out) then take a look at what we've been building with "faasd" and containerd - https://github.com/openfaas/faasd

There's also options for RPi and terraform over in the README - https://github.com/openfaas/faasd#tutorials
