How to launch an instance

In this tutorial we'll work through setting up a Leafcloud instance.

Navigate to Compute, then click on Instances


Click on Launch Instance, on the center right


Give your instance a unique name (ie. testinstance) and add a description.

The Availability Zone is the region where the instance will be deployed, the Count setting allows you to create multiple instances with the same settings, for the purpose of this tutorial make sure it is set to 1


Click on next


In this tutorial we will create a new volume and boot from a specific image.

Make sure your settings are as follows:

Boot Source: Image, check to make sure that Create New Volume is selected

Volume Size: 10GiB, check if Delete Volume on Instance Delete is not selected

Select Ubuntu-20.04.1 by clicking the up arrow on the right


Click on next


This is the type of server used to host your instance.

Select ec1.small, by clicking on the up arrow on the right. These ec sites are servers located at one of our Leaf-sites, where server heat is re-used locally


Click next


Here you can determine on which channels the instance will be reachable.

Select external, this gives your instance a public IP address

Key Pair

Here you can add a key pair to access your instance.

You can either Create a new key pair, import one from your computer or select one of the key pairs you've already added to openstack (under 'Available').
