Once the cluster is up, you can connect to it from your code. register_views () # Create the exporter that'll upload our traces to Zipkin. Let's start by looking at how you install redis-py using pip: pip install redis-py Alternatively, if you're using easyinstall, the installation command. register_exporter ( pexp ) # Register the defined ocredis views. To do this, I recommend amending your base.in file from. Options ( namespace = 'ocredispy', port = 8000 )) view_manager.
