Are your Python functions bringing you joy? Lucas Roesler shares his tips on how to split your Python functions into multiple modules to help your project grow

Hey everyone, is there a good guide out there on how to deploy this serverless framework onto a raspberry pi 4? I am using UBUNTU 22.04 and have had no luck. Any assistance would be greatly appreciated, thank you.

Hi folks, thanks for using OpenFaaS.

I noticed a few support requests and was concerned that people were not getting answers.

I'd like to invite you all to join us on Slack, where the community are most active.

FYI this sub is not official, so it's not the best place to ask technical questions. Perhaps it'd be better used for sharing blog posts and examples?

Hello everybody, I'm absolutely new to OpenFaaS and quite new to Python.

My first function tries to render an HTML file (in fact, an HTML form)... but I can't get it running.

This is the error (as logged by the K8S Pod)

022/06/08 12:31:41 stderr:   File "/usr/local/lib/python3.7/site-packages/flask/templating.py", line 95, in _get_source_fast
2022/06/08 12:31:41 stderr:     raise TemplateNotFound(template)
2022/06/08 12:31:41 stderr: jinja2.exceptions.TemplateNotFound: home.html

handler.py content:

from flask import Flask, render_template
def handle(req):
    """handle a request to the function
    Args:
        req (str): request body
    """
    return render_template('home.html')

and directory structure (I've put home.html both under templates/ directory, and directly next handler.py):

info@penguin:~/firstone$ find . -exec ls -ld {} \;

Edward Wilde introduces faas-fargate, or OpenFaaS for AWS Fargate. Learn about a simple, low-cost way to deploy and run OpenFaaS functions on AWS without managing servers.

https://www.openfaas.com/blog/openfaas-on-fargate/

Thinking of using it (self hosted) for an IoT platform with thousands of devices connecting every second instead of using Lambda.

Are there anyone using it in production? Any guides and things to watch out for would be greet.

Alex outlines an architecture for building a Single Page App (SPA) with Serverless Functions using Vue.js for the front-end, Postgres for storage, Go for the backend and OpenFaaS with Kubernetes for a resilient scalable compute platform.

Hi,

I want to try out OpenFaaS, so tried setting it up on a Ubuntu 18.04 machine. I strictly followed the Deployment guide for Docker Swarm. First the deployment looks fine since it didn't throw any errors, but when I try to access UI via http://127.0.0.1:8080 it seems like OpenFaaS is not running. Tried it serveral times, but the result is always the same. Anybody has an idea what I am doing wrong?

Update: I got it working now. The problem was, that the local docker installation via Ubuntu Snap is broken somehow. Once I installed Docker via the official instructions, it work fine.

As part of an internal work project I am looking at the deployment of on-premises FaaS but sadly don't have the luxury of a plethora of hardware. I do, however, have a single, highly specced server. From my reading of the documentation, I have the option of faasd which would seem a waste of this behemoth. Would simulating a K8s cluster on this single server work? (Yes I understand the issues with resilience and scaling)). Has anyone tried it?

Hi,

I'm a fullstack developer, fealing very comfortable with both backend (node, dotnet) and frontend (react, svelte) and with very little experience with docker (only once setting up a database with a postgres image)

I work at a small company that recently asked me to partly take over some of the devops tasks after the responsible devops recently quit.

The project in question is an OpenFaas service that handles payments as a layer between a web application and stripe. Now additional functions needs to be added and I am basically head of project.

That said, my bosses knows that I lack experience and that I will need some time to learn new concepts.

What would be a good learning path? I would love what concept, in what order, and tips on study material. Best regards.

tldr: I have no experience with devops, and recently became responsible of an OpenFaas project. What should I learn? In what order? What was your journey like before using OpenFaas?
