serverless-lambda-first-steps

This is a POC to try the serverless framework.

The goal is:

1. Create a index.js file with a simple function within it;
2. Configurate a yaml file mapping the provider and the lambda function that was created;
3. Deploy the lambda function using the Serverless framework;

Prerequisites

1. Make sure that you have a AWS account and AWS CLI configured as well.

2. Make sure you have installed all of the following prerequisites on your development machine:

   • Git;
   • Node.js and the npm package manager;
   • Serverless framework; npm i -g serverless

Installing the dependencies

Once the repo is properly cloned/forked into your machine, open the terminal on the project root and run:

npm install

Deploying the lambda using Serverless framework

sls deploy --verbose

By running this command, we can see at the logs that:

• the serverless framework will automagically create a S3 Bucket on AWS
• upload a CloudFormation file to S3
• deploy service to stack 'sls-my-first-lambda-dev'
