.. envvar:: OTEL_RESOURCE_ATTRIBUTES

The :envvar:`OTEL_RESOURCE_ATTRIBUTES` environment variable allows resource
attributes to be passed to the SDK at process invocation. The attributes from
:envvar:`OTEL_RESOURCE_ATTRIBUTES` are merged with those passed to
`Resource.create`, meaning :envvar:`OTEL_RESOURCE_ATTRIBUTES` takes *lower*
priority. Attributes should be in the format ``key1=value1,key2=value2``.
Additional details are available `in the specification
<https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#specifying-resource-information-via-an-environment-variable>`__.
