Upload 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.
To upload an image to FlexiHPC we will be using the command openstack image create to upload the image.
Using Ubuntu as an example, we will upload a new Ubuntu 22.10 (kinetic) image. Heading to the Ubuntu cloud images link for Kinetic images we want to select the image that has the description QCow2 UEFI/GPT Bootable disk image with linux-kvm KVM optimised kernel
With that download and accessible from your CLI we can upload it to FlexiHPC
openstack image create --file /path/to/your/image-file --disk-format disk_format --container-format container_format image_name
Replace the placeholders with the appropriate values depending on your environment:
/path/to/your/image-file- The local path to the image file you want to upload.
disk_format- The format of the image on disk, e.g., qcow2, raw, vhd, vmdk, etc. If your unsure then set the format to qcow2
Note
When it comes to the different image formats we generally follow the very basic guideline for them.
Images in the QCOW2 format are for running a single compute instance.
Images in the RAW format are for running multiple compute instances.
If you wish to convert to another format please read Converting Images between formats
container_format- The format of the container for the image, e.g., bare, ovf, aki (kernel image), etc. If you are unsure here then set the format to bare
image_name- The name you want to give to the uploaded image.
If we run the command with the supplied settings
openstack image create --file ~/openstackcli/iso/kinetic-server-cloudimg-amd64-disk-kvm.img --disk-format qcow2 --container-format bare Ubuntu-22.10-Wiki-Test
The command window will process silently as it uploads it to the FlexiHPC platform. We should then get a response from the FlexiHPC Platform

Note
Adding --wait to the end of the command will give you a progress bar rather then returning with the status queued
We should then be able to use the id returned to launch an instance from either the Dashboard or the CLI
