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) ===
-# From the Compute menu, select Instances
-# Press Launch Instance
-# Fill the following section
-'''Details'''
-Write the instance name (it's actually a prefix if more than one instance is being lauched), no spaces are allowed
-Choose the number of instances to launch
-'''Source'''
-        Select Image as boot source if you don't have the necessity to boot from a existing snapshot
-        Choose the Volume size
-        Select Yes for Delete Volume on Instance Delete
-        Select the chosen operating system image
-'''Flavor'''
-        Select the flavor of the VM. When launching more than one instance, every instance will have the same flavor (and the same OS)
-'''Network'''
-    Select the PROJECT-main Network
-    The public IP addresses can be assigned later
-'''Network ports'''
-    Not used by us
-'''Security groups'''
-    @ISTI The default one opens
-        ssh from the VPN gateways and using the proxy jump configuration.
-        http and https from the load balancers only
-        port 8100 from the proxy jump host (this is the port we use for the tomcat debugging service)
-        port 9100 from the prometheus server (node exporter)
-'''Key Pair'''
-    Select your key pair. You can create or import one if it's not present already
-'''Server groups'''
-    They can optionally be used to equally distribute the VMs on the hypervisor. They must be created in advance, from the Compute -> Server Groups menu
-'''Scheduler hints'''
-    Not used by us
-'''Metadata'''
-    Not used by us
-'''==>''' Now press '''Launch Instance''' , you'll be redirected to the instances page
-'''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.''
