How to set environment variables using sdk-node library

[alvin562]

I'm currently working on setting up opentelemetry for a nodejs service using the node-sdk. Does the sdk support the environment variables listed in the Opentelemetry specification https://opentelemetry.io/docs/reference/specification/sdk-environment-variables/. If so, is it set simple via environment variable or do we have to provide in the code in some way?

With Java it was as simple as setting an environment variable or passing via system property (-D). Just curious how it is done with node as I can't find any information on it. Thanks

Not every env variables are available, you can see the list there: https://github.com/open-telemetry/opentelemetry-js/blob/main/packages/opentelemetry-core/src/utils/environment.ts#L67. Also some are in progress like #2873
