Simplify the otel-collector example

[rakyll]

The otel-collector example is doing too much to be an entry level example. It'd great to keep the scope to just export OTLP to a collector running locally (via Docker) to provide an easy to setup entry point to developers.

Is this issue still need to be improved? I'd like to take it as below:

• Keep the former k8s setup example.
• Add a Docker example to export OTLP to a collector running locally by using docker-compose.

@rakyll thx.

Am I correct in my understanding that #2962 was closed and not accepted because of the name logger, and that it's a new example, instead of altering the original otel-collector example?

Is moving from microk8s to Docker to host the collector desirable, or is it best to retain the microk8s deployment and just simplify it?

+1 moving to just Docker and docker compose like the other instrumentation examples (e.g. https://github.com/open-telemetry/opentelemetry-go-contrib/blob/e2cab2e7ca4271c0d6474071a7ce48c0c274e840/instrumentation/github.com/gorilla/mux/otelmux/example/docker-compose.yml) do.

@MrAlias i would like to work on this if this is still needed(quick check at the examples gives the idea it yet to be completed).

If so i would modify the example to remove existing k8s deployment step and replace it with a docker compose based example.

Hi @MrAlias ,
I would like to work on it, if this is still needed.
Could you please confirm that the above PR #3560 is in process for merging or is being rejected?
