Hello @arorakanav 👋🏽

Have you seen that we already have a docker-compose.minimal.yml file?

The idea of creating a light version for the demo is about making it easier to configure more or less services that should run.
Ideally in a programmatic way.

I've done some tests using docker profiles at https://github.com/julianocosta89/opentelemetry-demo/blob/docker-add-profiles-to-compose/compose.yaml, but this initial PR was just to test how it would work, without changing anything on the current full/minimal experience.

@julianocosta89 i have gone through the minimal file and your PR and comments on the issue to use profiles. with all the knowledge i have been able to gather using profiles will still run dependent services. now while writing this is i think i can remove more dependencies from my file which can give us a light version. i also understand that the requirement to have less code to manage, i will do some more research and see if i can find a more programmable way to solve this issue.

@arorakanav I wonder how different this approach is from the docker-compose.minimal.yml approach?
