Getting started

Build a sample Application

Imagine we have a static website and need server logic to store contacts and validate data. This would require a server, a database and some code to glue it all together. With a serverless approach, we can just sprinkle little functions (that we call actions) on top of our static website and let OpenServerless take care of the rest. No more setting up VMs, backend web servers, databases, etc.

In this tutorial, we will see how you can take advantage of several services which are already part of a OpenServerless deployment and develop a contact form page for users to fill it with their emails and messages, which are then sent via email to us and stored in a database.

Openserverless CLI: Ops

Serverless development is mostly performed on the CLI, and OpenServerless has its tool called ops. It’s a command line tool that allows you to deploy (and interact with) the platform seamlessly to the cloud, locally and in custom environments.

Ops is cross-platform and can be installed on Windows, Linux and MacOS. You can find the project and the sources on Apache OpenServerless Cli Github page

Deploy OpenServerless

To start using OpenServerless you can refer to the Installation Guide. You can follow the local installation to quickly get started with OpenServerless deployed on your machine, or if you want to follow the tutorial on a deployment on cloud you can pick one of the many supported cloud provider. Once installed come back here!

Enabling Services

After installing OpenServerless on a local machine with Docker or on a supported cloud, you can enable or disable the services offered by the platform. As we will use Postgres database, the Static content with the Minio S3 compatible storage and a cron scheduler, let’s run in the terminal:

ops config enable --postgres --static --minio --cron

Since you should already have a deployment running, we have to update it with the new services so they get deployed. Simply run:

ops update apply

And with just that (when it finishes), we have everything we need ready to use!

Cleaning Up

Once you are done and want to clean the services configuration, just run:

ops config disable --postgres --static --minio --cron
