OpenTracing Tutorial - Python

Installing

The tutorials are using CNCF Jaeger (https://github.com/jaegertracing/jaeger) as the tracing backend, see here how to install it in a Docker image.

This repository uses virtualenv and pip to manage dependencies. To install all dependencies, run:

cd opentracing-tutorial/python
virtualenv env
source env/bin/activate
pip install -r requirements.txt

All subsequent commands in the tutorials should be executed relative to this python directory.
