FAQ

What is the root password of the VM?

The instances do not have a predefined root password. During deployment, the SSH public key you specify is automatically set up on the instance.

How can I connect to an instance?

The easiest way to access an instance is via a public floating IP.

How can I assign a public IP to my instance?

Simply click on the arrow next to your instance and on “Associate floating IP”. Then select a suitable floating IP. If no floating IP is available yet, you can request a new one.

How do I apply for a floating IP?

Click on “Access & Security” in the “Compute” section. Then click on the tab “floating IPs” and finally on “Allocate IP to Project”.

Why can't I connect to a floating IP?

The reason for this is probably an overly restrictive security group (see firewall). The default security group is comparable to a SoHo-Router. Outgoing everything is allowed, but incoming is blocked

How can I create additional security groups (firewall rules)?

Click on “Access & Security” in the “Compute” section. Then click on “Create Security Group”. Select a name and a description and then add the desired rules. Of course, the “Default” security group can also be extended by rules if desired

How can I change security groups of an already running VM?

Simply click on the arrow next to your instance and on “Edit Security Groups”.

How do I install the CLI on my workstation?

Most APIs provide version information under the base URL, e.g. enter the following into a web browser for Keystone version information: https://de-nbg6-1.noris.cloud:5000. A list of all URLs is available with “openstack catalog list” or in the GUI under “Project -> Compute -> API Access”
