Launch an Instance from an Image
Note
The openstack CLI will need to be setup to interact with the FlexiHPC system. Please read Setting up your CLI environment to interact with FlexiHPC to get started.
We highly recommend that you supply the parameter --key-name to allow connections with your SSH key
After you gather required parameters, run the following command to launch an instance. Specify the server name, flavor ID, and image ID.
openstack server create --flavor FLAVOR_ID --image IMAGE_ID --key-name KEY_NAME --security-group SEC_GROUP_ID --network NETWORK_ID INSTANCE_NAME
Example with the values supplied
openstack server create --flavor e3a1ec6d-9513-4b9f-9580-671c4eee1c21 --image a5c9b7b2-e77b-4094-99ac-db0cf5181da5 --key-name test-key-pair --security-group 7200b28f-9089-4797-a094-39f1995e6f0c --network d3a7ddb5-6582-42cf-978a-c99b4ed25ad4 test-instance-wiki

A status of BUILD indicates that the instance has started, but is not yet online.
A status of ACTIVE indicates that the instance is active.
Copy the server ID value from the id field in the output. Use the ID to get server details or to delete your server.
Check if the instance is online
The list shows the ID, name, status, and private (and if assigned, public) IP addresses for all instances in the project to which you belong:
+--------------------------------------+---------------------------------------+--------+----------------------------------------------+--------------------------+--------------------+
| ID | Name | Status | Networks | Image | Flavor |
+--------------------------------------+---------------------------------------+--------+----------------------------------------------+--------------------------+--------------------+
| 8b08a4fb-7372-4269-a583-9dbc91779ffe | test-instance-wiki | ACTIVE | NeSI-Training-Test=10.1.0.134 | Ubuntu-Jammy-22.04 | devtest1.2cpu2ram |
+--------------------------------------+---------------------------------------+--------+----------------------------------------------+--------------------------+--------------------+
If the status for the instance is ACTIVE, the instance is online.
If you would like to access your Compute instance outside the FlexiHPC platform you will need to associate a floating ip to your instance. Reading Manage Floating IPs via CLI, You should then be able to connect to your instance using ssh which is explained more in Connect to your instance by using SSH.
