Rationale

This snippet is a sample showing how to implement CloudWatch Logs streaming to ElasticSearch using terraform. I wrote this gist because I didn't found a clear, end-to-end example on how to achieve this task. In particular, I understood the resource "aws_lambda_permission" "cloudwatch_allow" part by reading a couple of bug reports plus this stackoverflow post.

The js file is actually the Lambda function automatically created by AWS when creating this pipeline through the web console. I only added a endpoint variable handling so it is configurable from terraform.

README

The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.

An example server

Create an simple echo server at /opt/foo/serve.py.
