Deploy resources on aws using CDK(and go)!

A basic setup for deploying lambda , apigateway and a dynamodb database using amazon cdk in golang.

This is what we deploy:

Cloudformation stack:

A simple user dynamodb table:

API gateway with the following API routes:

.. and a few lambda functions (check out lambda/api.go).

Setup:

• AWS account (a free account will work)
• Setup aws cli and cdk.
• cd into the lambda directory.
• make build
• cd back to root of the project.
• cdk diff to check what is being deployed.
• cdk deploy

A lambda function to register and login users will be deployed. This lambda function sits behind amazon api gateway and stores data in a dynamodb database.

Useful commands

• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth emits the synthesized CloudFormation template
• go test run unit tests
• cdk destroy to delete the stack.
