Basic Example

Minimal shell Lambda function using only the custom runtime layer.

What it demonstrates

• Shell script as Lambda handler
• Custom provided.al2023 runtime with the shell bootstrap layer
• Using built-in curl (no additional layers needed)

Architecture

handler.sh (curl) → runtime layer → Lambda (provided.al2023)

Usage

terraform init
terraform apply

Invoke:

aws lambda invoke --function-name shell-handler /dev/stdout

Handler

run () {
    curl -Ss https://wttr.in/?format=3
}

The runtime layer provides the bootstrap that sources handler.sh and calls the function specified in the handler setting (e.g. handler.run → sources handler.sh, calls run).
