Requests to the orderbook will then be routed to the secondary container that contains the change and will serve the orderbook via the nginx proxy rules.

Start the regtest setup as normal and view the orderbook. It might take some time for the ob-watcher.py script to complete initialization. If the orderbook is not served as expected immediately, see the obwatcher logs with:

docker exec -it jm_regtest_joinmarket2 tail -f /root/.joinmarket/logs/obwatch_stdout.log -n 200

.. and wait for the following message

started http server, visit http://127.0.0.1:62601/
