Accessing The Cloud¶
Prerequisites¶
Resources on the JUSUF CLOUD Cloud are granted through the Fenix Research Initiative. By default, the Fenix AAI federated identity service is used to authenticate to JUSUF CLOUD Cloud. In case of technical issues, authentication via LDAP through our JUDOOR web portal can be offered as a work around.
In both cases the Acceptible use Policy needs to be accepted.

WebUI¶
Go to the JUSUF OpenStack Dashboard.
Fenix AAI¶
Select Authenticate using -> Fenix AAI
You will be forwarded the Fenix AAI where you can select your local Identity Provider. After authenticating you are send back to the OpenStack Dashboard.
JUDOOR¶
Select the Authenticate using -> Keystone Credentials, Domain -> JUDOOR Account and then use your credentials.
Command Line Interface (CLI)¶
One very prominent interface to a OpenStack environment are comandline tools. These are available via pip within an Python environment, and come together with Python libraries to interact with openstack.
$ python3 -m venv openstack
$ source openstack/bin/activate
$ pip install python-openstackclient
The official OpenStack CLI documentation is available here
Fenix AAI¶
We are sorry, the authentication mechanism picked by Fenix, namely OIDC, is not supported by the CLI yet.
JUDOOR¶
When you used the JUSUF OpenStack Dashboard before switching to the CLI, you can download a credential file there.
Authenticate at the JUSUF OpenStack Dashboard

Alternatively you can create the RC File on your own:
#!/usr/bin/env bash
export OS_AUTH_URL=https://jusuf-cloud.fz-juelich.de:13000
export OS_PROJECT_NAME="YOUR_PROJECT"
export OS_USER_DOMAIN_NAME="JUDOOR"
export OS_USERNAME="YOUR_USER"
# With Keystone you pass the keystone password.
echo "Please enter your OpenStack Password for project $OS_PROJECT_NAME as user $OS_USERNAME: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT
export OS_REGION_NAME="jusuf"
export OS_INTERFACE=public
export OS_IDENTITY_API_VERSION=3
