Docker compose override for OpenTelemetry zero-code instrumentation

If you want to add OpenTelemetry to the services in an existing docker-compose.yml you can use a docker-compose.override.yml to do so without touching your existing file.

Imagine you have three services listed called frontend, processing and backend in your compose file. Two of them are written in Java, one of them in Node.JS. Create the following docker-compose.override.yml file alongside your docker-compose.yml to inject the Java agent and the @opentelemetry/auto-instrumentations-node package into them:

	- name: Traces
	description: ""
	features:
	- feature group: TracerProvider
	features:
	- feature: Create TracerProvider
	optional: false
	status:
	go: supported
	java: supported

	'use strict';

	const { diag, DiagConsoleLogger, DiagLogLevel } = require('@opentelemetry/api');
	const { NodeTracerProvider } = require('@opentelemetry/node');
	const { NetInstrumentation } = require('@opentelemetry/instrumentation-net');
	const { DnsInstrumentation } = require('@opentelemetry/instrumentation-dns');
	const { registerInstrumentations } = require('@opentelemetry/instrumentation');
	const { SimpleSpanProcessor, ConsoleSpanExporter } = require('@opentelemetry/tracing');

	const provider = new NodeTracerProvider();

	const appdynamics = require("appdynamics")
	appdynamics.profile({
	controllerHostName: '.saas.appdynamics.com',
	controllerPort: 443,
	controllerSslEnabled: true,
	accountName: '',
	accountAccessKey: '',
	applicationName: '',
	tierName: '',
	debug: true,

	function globalSearch(value, max = 100000) {

	var stack = (function () {
	iframe = document.createElement('iframe');
	document.body.appendChild(iframe);
	var results = Object.getOwnPropertyNames(window).filter(p => !iframe.contentWindow.hasOwnProperty(p)).map(p => {return {type: typeof window[p], name: p, value: window[p]}}).reduce((c,p) => {
	c.push([p.value, 'window.' + p.name]);
	return c;
	}, []);
	document.body.removeChild(iframe);

	const fs = require('fs');

	let flowmap = JSON.parse(fs.readFileSync('flowmap.json'));

	const nodeCount = 1
	const edgeCount = Math.floor(nodeCount * 1.5)

	const fileName = `flowmap-${nodeCount}.json`

	const nodeString = JSON.stringify(flowmap.nodes[0])
