Debug OpenStack Tacker in PyCharm

1. Stop tacker service

sudo systemctl stop devstack@tacker

2. In the PyCharm, open the tacker (/opt/stack/tacker) and debug with:

/usr/local/bin/tacker-server --config-file /etc/tacker/tacker.conf

When we finish the debugging, we can start tacker service again with:

sudo systemctl start devstack@tacker
