Command line interface (CLI) access
For advanced users it is possible to manage the cloud instances from the command line interface.
THE GUIDE IS TESTED ON UBUNTU 18.04 For CLI access, the OpenStackClient (OSC) must be installed. USE PIP The package in apt does not work for SAML2 Authentication.
Linux
$ sudo apt install python3-openstackclient
# or
$ pip install python-openstackclient
# If pip is not installed run
$ sudo apt install python-pip
Mac
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
pip install python-openstackclient
Get token
From a internet browser, login to this openstack wayf auth and inspect the Response Headers and find the X-Subject-Token. How to find the Response Headers varies from browser to browser. To find the Response Headers checkout this guide https://www.dev2qa.com/how-to-view-http-headers-cookies-in-google-chrome-firefox-internet-explorer/ which covers the most common browsers.
After you have found the X-Subject-Token, login to strato-new as normal. In the upper right corner, find and click your AAU ID (XXZZXX@aau.dk), and then "OpenStack RC File". Open or save the file. Start a terminal, and export the following variables (you need to locate a few values from the "OpenStack RC File"):
export OS_AUTH_TYPE=token
export OS_IDENTITY_API_VERSION=3
export OS_AUTH_URL=https://strato-new.claaudia.aau.dk:5000
export OS_PROJECT_ID=<project ID as given in the OpenStack RC File>
export OS_PROJECT_NAME=<your name as given in the Openstack RC File>
export OS_TOKEN=<value of **X-Subject-Token**>
If successful, you can now test your setup like
openstack server list
$ openstack server list
