Deploying current wallaby-based stack using Ubuntu containers on Ubuntu host systems with trove single tenant set to yes, attempting to access the Trove Horizon view results in:
```

which i imagine is not the intended outcome of that operation.

Whats the proper way to hot-patch containers with dependencies while stuff is resolved upstream? I have a local repo docker repo as a proxy already.

I would suggest trying to fix it yourself, then propose the fix upstream.

I can add this to my backlog, but i'm booked out for months with client work and other Open Source commitments (also i'm not a Python developer, Ruby is my game for interpreted languages). If you could point me to the procedures i requested in terms of modifying the containers, i can take a quick stab at it next time i have some free time. Otherwise i'll need to allocate actual project time somewhere in Q4 in our project management system (Trove isn't required for us, but a neat function to have available).

The default value have been change, you can overwrite by putting bellow configuration into /etc/kolla/config/trove.conf.

And of course, we should update this in kolla template as well

# Client to send Nova calls to. (string value)
#remote_nova_client = trove.common.clients_admin.nova_client_trove_admin

# Client to send Neutron calls to. (string value)
#remote_neutron_client = trove.common.clients_admin.neutron_client_trove_admin

# Client to send Cinder calls to. (string value)
#remote_cinder_client = trove.common.clients_admin.cinder_client_trove_admin
