Example incorrect about rustracing_jaeger

[sile]

Hmm, I tried running the example code with the jaeger that started by the above docker command, but it worked correctly in my environment.

The one I wrote on my report is the ufficial version as found on jaeger documentation (https://jaeger.readthedocs.io/en/latest/getting_started/), your version is clearly missing parameters:
docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 jaegertracing/all-in-one:latest

I understand what you mean.

Indeed, my example uses a docker command that is different from what is written in the official document.
But it is sufficient for the example, and I like to use simple command rather than unnecessary long command for examples.

So, as an alternative, I'd like to add the following notes, what do you think?

# Run jaeger in background
#
# Note that the following command only specifies the minimum options required to run this example.
# For the complete command, please refer to the Jaeger's official documentation.
# (e.g., https://jaeger.readthedocs.io/en/latest/getting_started/)
#
$ docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 jaegertracing/all-in-one:latest
