erllambda Deployment Tutorial

To create AWS Lambda function, it's required to provide a zip package with function code.

Bootstrapping

AWS Lambda functions with a provided runtime expects that package contains executable bootstrap file in the root of the zip archive. bootstrap is an entry point for a provided runtime. When AWS Lambda container boots, bootstrap file is executed to start a provided with a package runtime.

In the current implementation erllambda provides a script, which can be used as an entry point to boot OTP release.

It might be used by other projects (like rebar3 erllambda plugin) as a bootstrap file. Other projects (like mix erllambda plugin) might have a custom bootstrap file. erllambda does not require runtime to be started using the start script in the repository.

Packaging

erllambda doesn't know how to build a zip package.

There are currently 2 projects that help with packaging:

• Plugin for rebar3 rebar3_erllambda
• mix task mix_erllambda

Created packages should be suitable for deployment as AWS Lambda functions with provided environment.

For further details please see documentations of mentioned projects.
