On SDK level you can add it though environment variable OTEL_RESOURCE_ATTRIBUTES=deployment.environment=prod

On collector level you can add it through a resource processor.

processors:
  resource/env:
    attributes:
    - key: deployment.environment

      action: upsert
...
service:
  pipelines:
    logs:
      processors: [resource/env, batch]
