Cloud-Calcolo&Storage

We have an on premise OpenStack cluster, with distributed storage based on Ceph.The OpenStack@ISTI dashboard is reachable at https://isti-cloud.isti.cnr.it/. All the pre-authorized ISTI users have access from default to the LAB-cloud project (where LAB is the ISTI laboratory user belong to).

Virtual Machines Management using the dashboard

The OpenStack dashboard is available at ISTI at the following URL: https://isti-cloud.isti.cnr.it/dashboard/project/

Launch an instance (which means Create Instance)

1. From the Compute menu, select Instances
2. Press Launch Instance
3. Fill the following section

Public Ip addresses (Floating IP)

You can now add a public IP address to your instances using the Associate Floating IP item of the menu associated to the VM.

Important : in the ISTI infrastructure, you can associate a FQDN to the floating IP address. You have to add the hostname and the domain (ending with a .) in the form used to allocate the floating IP addresses. Note that the operation gives back an error, but the operation still completes successfully. If you are unsure about the domain name, you can find it in the DNS -> Zones menu.
