logstash-http-example

I wanted to test how a custom plugin could be integrated into a logstash pipeline using the builtin http filter plugin. A go plugin providing the HTTP service mimicks some transforming service.

⚠️ This is a quick and dirty proof of concept example! Security or error handling is not a concern here!

Usage

It's a docker compose project, so simply run:

docker compose up

And you should see something like:

logstash-http-plugin-logstash-1 | {
logstash-http-plugin-logstash-1 | "message" => "Sample fox 3",
logstash-http-plugin-logstash-1 | "response_json" => {
logstash-http-plugin-logstash-1 | "number_doubled" => 6,
logstash-http-plugin-logstash-1 | "animal_repeated" => "foxfox"
logstash-http-plugin-logstash-1 | },
logstash-http-plugin-logstash-1 | "number" => "3",
logstash-http-plugin-logstash-1 | "animal" => "fox",
logstash-http-plugin-logstash-1 | "response_plain" => "Received: 3"
logstash-http-plugin-logstash-1 | }
logstash-http-plugin-logstash-1 | {
logstash-http-plugin-logstash-1 | "message" => "Sample snake 4",
logstash-http-plugin-logstash-1 | "response_json" => {
logstash-http-plugin-logstash-1 | "number_doubled" => 8,
logstash-http-plugin-logstash-1 | "animal_repeated" => "snakesnake"
logstash-http-plugin-logstash-1 | },
logstash-http-plugin-logstash-1 | "number" => "4",
logstash-http-plugin-logstash-1 | "animal" => "snake",
logstash-http-plugin-logstash-1 | "response_plain" => "Received: 4"
logstash-http-plugin-logstash-1 | }

Exit the setup with Ctrl + C.
