This project builds a function to be run on AWS Lambda and automatically releases it as part of the CI/CD pipeline.

You need access to a private repository in order to be able to build the whole project. However you can use this as an example on how to use AWS Lambda with Haskell.

Build with

. .env
make

Run locally with

make run-local

and call the lambda with

curl -X POST http://localhost:9000/2015-03-31/functions/function/invocations -H 'Content-Type: application/json' -d '{"type":"SAVE", "payload": "<payload>"}'

The repository is configured to build a docker image containing the lambda, publish it to AWS ECR and call terraform cloud to update the lambda. The secrets that need to be configured are:

• AWS_REGION: the aws region where the ecr resides
• AWS_ECR_IMAGE: the name of the ecr
• AWS_KEY_ID and AWS_SECRET_KEY: the aws credentials
• TF_TOKEN: an api token generated on terraform cloud
• TF_WORKSPACE: the workspace on terraform cloud

aws lambda invoke --function-name <function> --cli-binary-format raw-in-base64-out --payload '{"type": "SAVE", "payload": "<payload>"}' out.json
