Can I use resource detectors combined with some custom resource attributes?

[ikigai-chiawen-c]

I need to use a resource detector while also specifying some resource attributes manually, can I use both of resources and resourceDetectors property of NodeSDK api at the same time? Which one will take precedence when some attributes conflict?

const sdk = new opentelemetry.NodeSDK({
  resourceDetectors: [dockerCGroupV1Detector],
  resource: resourceFromAttributes({
    [ SEMRESATTRS_SERVICE_NAME ]: process.env.SERVICE_NAME,
    [ SEMRESATTRS_SERVICE_INSTANCE_ID ]: randomUUID(),
  })
});

you can use both. 🙂
The explicit resource you passed will take precedence over the one from the detectors.

If you need to change the precedence, please use detectResources() from @opentelemetry/resources and Resource#merge() on resulting resource to merge them according to your preferred precedence :)
