Hi,
Cylc Hub is just Jupyter Hub, configured for Cylc use, extensive documentation can be found here.
Jupyter Hub is something that has to be deployed by system administrators as it requires raised privileges to function.
By default, Jupyter Hub is configured to use system authentication, so should work with your regular username/password. However, in order for this to work, you must list the user accounts you wish to grant access, to enable all accounts, add this configuration:
# ~/.cylc/uiserver/jupyter_config.py
c.Authenticator.allow_all = True
The web interface you remember is indeed Cylc Review. This isn’t available at the time of writing as we have just finished porting it to Cylc Hub, but haven’t released it yet.
Keep an eye on the 8.6 release thread, we’ll announce the release of cylc-uiserver 1.9.0 shortly which will include setup instructions for running Cylc Review behind Jupyter Hub.
For multi-user setups, Cylc Hub must be installed with the required permissions, however, for evaluation, we’ll be able to run Cylc Review standalone for single-user applications.
The new version of Cylc Review continues to provide the capability to provide a “public” web app that does not require login.
