Hi 🙌
This is a fix, for
OTEL_RESOURCE_ATTRIBUTESenvironment variable, as currently this env var will not be used which could lead to some confusion as other env vars work.Background of this is, that in open-telemetry/opentelemetry-go#1689 support for merging this resource variable was added, but it was moved in open-telemetry/opentelemetry-go#2120 (comment) to the
resource.New()function.Through using
resource.New()we do not need to add additional command-line arguments but can leverage the merging behaviour.
