openstack-dashboard horizon is in broken in a non-operational state

[Pedro Victor Lourenço Fragola]

[Description]
The Openstack charm of the Stein version with the following versions/revs:

openstack-dashboard version 15.3.1 - rev 490
openstack-dashboard version 15.3.1 - rev 308

octavia-dashboard version 3.0.1 - rev 42
octavia-dashboard version 3.0.1 - rev 19

When trying to access the horizon url it is in a broken state as shown in the attached image (broken.png).

When I enable DEBUG by juju I have the following message in the browser
"You have offline compression enabled but key "cd7532f8e831ce92774ff026f1b711f60e7dcbb1891fce186d67729f0c6c0988" is missing from offline manifest. You may need to run "python manage.py compress". Here is the original content:"

[Reproduction]

1) Default value after install

juju config openstack-dashboard offline-compression
true

local_settings.py => COMPRESS_OFFLINE = True

When accessing horizon I have a non-operational state as shown in the image(broken.png)

2) When setting DEBUG
juju config openstack-dashboard debug=yes

I have the message in the browser as shown in the image(debug.png)
"You have offline compression enabled but key "cd7532f8e831ce92774ff026f1b711f60e7dcbb1891fce186d67729f0c6c0988" is missing from offline manifest. You may need to run "python manage.py compress". Here is the original content:"

3) Changing the parameter manually
After change /etc/openstack-dashboard/local_settings.py the parameter COMPRESS_OFFLINE to False I have a healthy state as shown in the image(work.png)

COMPRESS_OFFLINE = False

4) Setting the parameter by Juju

juju config openstack-dashboard offline-compression=no or juju config openstack-dashboard offline-compression=false

COMPRESS_OFFLINE = True

The parameter is not changed to False

[Impact]

It is not possible to change the parameter by Juju only manually.

Horizon only works with the COMPRESS_OFFLINE parameter as False, but it is only possible to do this manually

This could be a duplicte of LP #1902890.

The workaround that worked for me was:

juju run --model openstack --application openstack-dashboard -- "cd /usr/share/openstack-dashboard/openstack_dashboard; sudo python3 /usr/share/openstack-dashboard/manage.py compress; sudo systemctl restart apache2"

[Pedro Victor Lourenço Fragola (pedrovlf)]

I did the suggested workaround and now I have a healthy status for Horizon.

In your bundle is Octavia used as a plugin?

Thank you for the information.

[Przemyslaw Hausman (phausman)]

hi @pedrovlf, no I don't have Octavia in the bundle.
