I’d like to introduce you to Tarun from Iconscout who is our guest-writer for today’s end-user blog post. Tarun will guide us through how to resize images on the fly with OpenFaaS.

Last August I wrote a post showing how you could set up OpenFaaS on DigitalOcean with Kubernetes or Docker Swarm in 5 minutes. This week saw the culmination of a collaboration between DigitalOcean and the OpenFaaS community, which resulted in the general availability of an OpenFaaS one-click Droplet image. This makes it even easier to deploy OpenFaaS in the most cost-effective way with DigitalOcean.

As a core contributor to OpenFaaS, you’ll find me in the OpenFaaS Slack hanging out and ready to help new users and contributors. You can join the community here. This was post inspired by a question from a new user who had just joined the community. He asked:

Today I want to tell you about a new feature released in OpenFaaS that unifies the experience of working with secrets. We introduced the ability to manage secrets in one consistent way whether you are using Kubernetes, Swarm or Nomad. The changes we made to the REST API and CLI simplify the amount of commands you need to learn and remember to manage confidential data used by your functions.

I would like to introduce you to the new Template Store feature which has been developed in the community to make it even easier to discover and share custom function templates for your serverless functions. We’ll look at how serverless platforms such as AWS Lambda package functions in zip files along with some of the pros and cons. We’ll then take a quick look at how OpenFaaS packages functions using the Docker/OCI image format and learn how to discover custom function templates using the new template store feature.

I want to share some news with you. We’ve merged and released support for stateless microservices in OpenFaaS 0.9.0. This means you can now take advantage of the simple, but powerful developer experience of OpenFaaS as a single pane of glass to manage your FaaS functions and microservices. The whole experience is included from the CLI, to the Prometheus metrics to the built-in auto-scaling. Even scaling to zero is supported. I’ll walk you through deploying a Ruby and Sinatra guestbook backed by MySQL deployed to OpenFaaS with Kubernetes.

This article will demonstrate how to have an OpenFaaS instance up and running on a DigitalOcean droplet in around 5 minutes through an Ansible playbook. You can pick either Kubernetes or Docker Swarm in the tutorial.

In this post I’ll share 5 top tips for boosting productivity with the OpenFaaS CLI. The CLI is used by developers to interact with OpenFaaS from the terminal is the most popular part of the project for new contributors to cut their teeth on. Since 2017 the contributors been incrementally fine-tuning the developer-experience through user-feedback, new features and productivity-boosters.

This is a guide on how to set up OpenFaaS on Google Kubernetes Engine (GKE) with a cost-effective, auto-scaling, multi-stage deployment.

In this post I’ll highlight one of the ways we’re making OpenFaaS a more secure environment for your production functions and workloads.
