Currently, Pyforge is configured to use the IdentityCloud instance as it is set up when the tenant is created, and then set in config.cfg as follows:
This is using user specific config options - for `admin_user`, which is not ideal. Using a generic accessible IG QA email address would be better.
Note that the hostname also will change according to the environment, as it's not recommended to reuse the same tenant name (so same hostname) between environments. This is due to time factors when they're torn down - and can lead to an unreliable build of the new environment.
