How to use a different path for Monocular
The default path for ui is / and api is /api/. How to change the default path like /monocular/ and /monocular/api/?
I just change the ingress settings but it didn't work.

Hmm @shenxg13 this looks it should work. Can you try removing the trailing slashes at the end of the paths (/monocular/api/ -> /monocular/api). Not sure if that will make any difference. It would be useful to see the generated vhost (debug the nginx ingress controller configuration).

@shenxg13 so from the looks of it, the API works fine, the issue is the UI. Can you check the Network tab in your browser's JS console to see what paths it's requesting. It's likely that the UI is not expecting to be mounted at /monocular and is not using relative URLs. Could be related to https://github.com/kubernetes-helm/monocular/issues/242.
@shenxg13 looks like the UI is not correctly adding the /monocular subpath to those requests, we'll probably need to update the URLs to be relative. In the meantime, are you able to use a subdomain instead of a path?
Hello , I've got the same trouble with path /monocular/ Do you plan to have URLs relative soon ?
