To access the OpenStack platform using the client, different Environment Variables must be set as described here.
So, connect to your RHOS instance (e.g https://rhos-d.infra.prod.upshift.rdu2.redhat.com/) and select within the menu: Project > API Access.
From there, download the OpenStack RC file bash file by clicking on the button and store somewhere (e.g ./rhos-openrc.sh).
Copy the file to a path directory, for instance ~/bin (or ~/.local/bin or /usr/local/bin) and give it execution permission.
Source the bash script source /usr/local/bin/rhos-openrc.sh and enter your password as requested.
Please enter your OpenStack Password for project xxxxxxxxxx as user xxxxxxxxxxxx:That’s it, you’re now logged in.
