Deployment using Serverless

Prerequisites

• Install Node

  • Mac (assuming you already have Homebrew installed):

    brew install node
    

  • Windows: Install WSL first (Windows Subsystem for Linux) and then install it in Ubuntu/Debian/SuSE...

  • Other: https://nodejs.org/en/download/

• Install serverless

npm install -g serverless

• Install AWS CLI: https://aws.amazon.com/cli/

Step 1: Install and prepare credentials

You need credentials to manipulate your AWS account from command line, if you don't have these already:

• Login to AWS Console in a web browser and add an IAM user:
  • Access type: Programmatic access
  • Attach existing policy: AdministratorAccess

Grab Access key ID and Secret Access key and store them in a safe place.

Step 2: Edit serverless.yaml

• Change line 32 instanceName with the name of your instance in LightSail.
• Change line 34 labelTag so the snapshots have unique names in case you create more Lambda functions for other instances.
• Change line 8 and 30 region with the region where your LightSail instance is.

Step 3: Setup

• In command line define your credentials and region so AWS CLI can do changes in your account:

export AWS_REGION=
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=

Step 3: Deploy

• Create and/or update everything using serverless:

sls deploy

• Test your function (optional)

sls invoke -f instance1
