kiennt26Hi team, I am working to implement Zaqar role in kolla-ansible. Have a few questions about the installation:08:44
kiennt26Zaqar works with one transport driver (wsgi or websocket) or we can config both of them at the same time?08:44
kiennt26I see in the zaqar/conf/drivers, user have to config which transport driver will be used. (default it is wsgi)08:45
kiennt26but in the devstack/plugin.sh, there are both drivers be configured08:45
kiennt26https://github.com/openstack/zaqar/blob/master/devstack/plugin.sh#L24608:46
kiennt26Which one is the right way to install Zaqar?08:46
thervekiennt26: You need one for each transport08:57
therveI'm pretty sure devstack uses a tricky08:58
therveA trick08:58
therveSo yeah, the "drivers transport" value only matters if you run "zaqar-server"09:00
thervedevstack uses zaqar-server for websocket, and uwsgi for wsgi09:00
kiennt26therve: It means that I need to setup both transports (wsgi and websocket), right?09:01
thervekiennt26: Depends what you want to do ...09:01
therveYou can't setup both in the same configuration file09:01
kiennt26therve: I almost get it, so I can setup both zaqar websocket and wsgi but each one uses different configuration files. Websocket zaqar-server and zaqar-wsgi can run standalone without each other.09:07
thervekiennt26: Yes09:07
therveIf you use a wsgi container, you can use the same config file too09:08
kiennt26therve: Great, thanks for your help. One more question: do I need to create databases in mongodb before install Zaqar?09:13
kiennt26Do Zaqar work without issue in multinode scenario?09:14
thervekiennt26: You don't to use mongo, but mongo schema is created dynamically iirc09:15
therveOnly the sql backend schema needs to be pre-created09:15
therveNot sure what you mean by multi node scenario09:16
kiennt26therve: very useful information, thank a lot.09:17
kiennt26I mean if I deploy zaqar-server in several nodes and do the same thing with zaqar-wsgi.09:17
therveSure that should work09:18
kiennt26therve: nice, thank again, you're amazing. Just get stuck with these concerns a couple days and now everything is clear.09:22
