AWS Lamba SAM Lamba Deployment with Scheduled Service

Boilerplate for creating/deploying an AWS lamba service with schedule cron expression service using SAM.

Step 1 - Log in AWS account in command line

1 Log into aws cli

aws cli
aws configure

Step 2 - SAM - Serverless Application Model

1 install aws-sam-cli

https://itnext.io/creating-aws-lambda-applications-with-sam-dd13258c16dd

pip install aws-sam-cli

2 Create sam version template (SAM templates extend Cloudformation)

Note must include the AWS:Serverless-2016-10-31 Transform key. You don't need to touch anything here unless instructed.

This is ./deployment/template.yaml file

3 Make a bucket first

aws s3 mb s3://sam-deployments-bucket

4 Package and Deploy it

Update the deployment.yaml file with the desired CRON expression

sam package --template-file ./deployment/template.yaml --output-template-file ./deployment/package.yaml --s3-bucket sam-deployments-bucket

sam deploy --template-file ./deployment/package.yaml --stack-name sam-deployment-boilerplate --capabilities CAPABILITY_IAM

5 Delete it

This will stop the entire service.

aws cloudformation delete-stack --stack-name sam-deployment-boilerplate
