Contributing- Unable to log to file using Otel Collector exporter

[SantoshAvaji]

I have created new file and provided all permission then given that path in yml config (It's in Ubuntu machine) exporters: file: path: ./filename.json

But facing an issue permission denied Unable to write file, please help me to resolve this issue asap

This problem is more appropriate in the otel col contrib repo, However, I think you should read the fileexporter's readme.md carefully first: https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/exporter/fileexporter

The official opentelemetry-collector-contrib container does not have a writable filesystem by default since it's built on the scratch layer. As such, you will need to create a writable directory for the path, potentially by mounting writable volumes or creating a custom image.

as @JaredTan95 said, this is a good question for the collector community, #otel-collector channel on CNCF Slack might be a good place to ask this. If there is any docs related issue please update accordingly
