If you want to enable traces, you can still set the env to your collector. Signed-off-by: Pat Riehecky <riehecky@fnal.gov>

There was a problem hiding this comment.
I don't think anyone else would use this Dockerfile to build with a different default (other than our own use).
If that would be the case, we could add some build-arg in future, e.g. something like;
# DEFAULT_OTEL_TRACES_EXPORTER sets the default OTEL_TRACES_EXPORTER to use
ARG DEFAULT_OTEL_TRACES_EXPORTER=none
ENV OTEL_TRACES_EXPORTER=${DEFAULT_OTEL_TRACES_EXPORTER}Which would allow the default to be set when building the image;
docker build -t foo --build-arg DEFAULT_OTEL_TRACES_EXPORTER=<whatever> .

This updates the default container invocation to avoid spamming the system logs with failure to send trace data.
I think this resolves #4270 while leaving it easy for folks using this to setup their collectors.
