I think default value for protocol should be https. We can have a special case to use http as a default when endpoint == DEFAULT_ENDPOINT.

I'm kinda wondering if the configuration parameters should just be a URL instead of protocol/host/port/endpoint. Looking at the other implementations, it looks like that is how they've implemented it. This would also simplify supporting that env variable.

I think that makes sense. My only concern is how users can discover the path part of the URL. If a user knows their zipkin endpoints is available at https://zipkin.corp.com, would they know or remember to add :9411 and /api/v2/spans? Perhaps documenting the default value in zipkin exporter docs would be enough of an indication?

Going with documenting the default value for now.
Good point, updated the docs |
