Launching instances using OpenStack Horizon

This will walk you through launching an instance from OpenStack Horizon.

Note

If you don’t have a network or SSH-keys available in some of the steps below, you might need to do some initial configuration first. An SSH-key created or added in the Cloud management portal is not available in Horizon as they use API users and SSH-keys are owned by the user account and not the project.

  • Under Project, click Compute and then Instances in the left-hand side menu.

  • Click the Launch an instance button in the upper right corner.

Caution

If you want to create an instance in the europe-se-1b availability zone (any availability zone that is not the default europe-se-1a) youneed to create the volume in that availability zone beforehand and in the Sources step select Boot Source as Volume. This is because we do not support attaching volumes across availability zones and the instance and volume must be in the same availability zone.

  • Under the Details tab in the dialog.

    • Enter an Instance Name for your instance and optionally provide a description.

    • Select an Availability Zone, see Regions and Availability Zones.

      • We recommend the default europe-se-1a availability zone if you are creating your first instance and if you are not sure that you need to use a secondary availability zone.

  • Under the Sources tab in the dialog.

    • Select Image as Boot Source.

    • Select Yes for Create New Volume to boot your instance from a volume, we only recommend selecting No here if you intend to use an NVMe-based flavor.

    • Select No for Delete Volume on Instance Delete. If you want the system to implicitly delete the volume together with the instance, select Yes.

    • Select the Image you want to boot your instance from by pressin the arrow on the right-hand side.

  • Under the Flavour tab in the dialog.

    • Select the flavor you want the instance to have by pressing the arrow on the right-hand side.

  • Under the Networks tab in the dialog.

    • Select the network you want to connect your instance to by pressing the arrow on the right side. This could be a private network if you have one or a directly attached IP in which case the availability zone is in the name of the network. We recommend using a private subnet, for more information see our Launching an instance guide.

  • Under the Key Pair tab in the dialog.

    • Select the SSH key you want added to the instance by pressing the arrow on the right-hand side. This is optional and mostly relevant for images and operating systems containing a SSH server.

  • Click the Launch Instance button in the bottom right in the dialog.

When the instance is finished its status will be Active. You can view more details about the instance by clicking the name in the list.

To reach your instance see the documentation for that.
