OCaml Runtime for AWS Lambda
This package provides a custom runtime for AWS Lambda.
Example function
See the examples
folder.
Deploying
Note: Based on the instructions in this blog post and the Rust custom runtime repository
For a custom runtime, AWS Lambda looks for an executable called bootstrap
in the deployment package zip. Rename the generated basic
executable to bootstrap
and add it to a zip archive.
The Dockerfile (in conjunction with the build.sh
script) in this repo does just that. It builds a static binary called bootstrap
and drops it in the target directory.
$ ./build.sh && zip -j ocaml.zip bootstrap
Now that we have a deployment package (ocaml.zip
), we can use the AWS CLI to create a new Lambda function. Make sure to replace the execution role with an existing role in your account!
$ aws lambda create-function --function-name OCamlTest \
--handler doesnt.matter \
--zip-file file://./ocaml.zip \
--runtime provided \
--role arn:aws:iam::XXXXXXXXXXXXX:role/your_lambda_execution_role \
--tracing-config Mode=Active
You can now test the function using the AWS CLI or the AWS Lambda console
$ aws lambda invoke --function-name OCamlTest \
--payload '{"firstName": "world"}' \
output.json
$ cat output.json # Prints: {"message":"Hello, world!"}
