About this automation

Deploy Bash scripts as AWS Lambda handlers using a custom runtime layer. Bundled with jq for JSON parsing and curl with AWS SigV4 support for signing AWS API requests. Handler reads stdin, writes stdout, returns 0 for success. Supports shell scripts, static binaries, or combinations thereof.

How to implement

1

Add the Bash runtime as a Lambda layer to your AWS account

2

Write your handler as a Bash script reading from stdin and writing to stdout

3

Use jq to parse JSON payloads from Lambda events

4

Call external HTTP APIs or AWS services with curl (use --aws-sigv4 for AWS authentication)

5

Return exit code 0 for success, non-zero for errors

6

Package optional static binaries alongside your handler script

7

Deploy and invoke via standard Lambda mechanisms
