How to upload and use custom images

Estimated time to read: 2 minutes

Introduction

Cyso Cloud offers ready to go images to help you get your instance up and running in no time. We offer images of the most used Linux distributions, but you can also upload your custom images. In this tutorial, we will show you how you can upload your custom image and boot it as an instance using the OpenStack CLI tools.

The following image files are supported: ISO, OVA, PLOOP, QCOW2, Raw, VDI, VHD, VMDK, AKI, AMI, ARI, Docker.

Prerequisites:

  • Active Cyso Cloud account
  • OpenStack CLI tools installed
  • An image (it's not possible to use a live image)
  • OpenStack credentials (open.rc file)

Step 1: Uploading your custom image

Make sure you are logged in to Cyso Cloud with your CLI tools 

$ source <your_openrc.sh>
We have to upload your image to Cyso Cloud. In this example, we use a qcow2 file. Upload your image using the following command. 
$ openstack image create --container-format bare --disk-format qcow2 --file <image_file_path> <name_your_image>
After the upload of your image is complete, you should see your image in the list. 
$ openstack image list

Step 2: Boot your image in Cyso Cloud

Before we can start our instance using our newly uploaded image, we need to specify a couple of things like flavor, network, security group, and key pair that we want to use.

Check the list of available flavors using the following command: 

$ openstack flavor list
Check your available networks 
$ openstack network list
Your security groups 
$ openstack security group list
Your key pairs 
$ openstack keypair list
Now for launching an instance using your custom image we can use the following command: 
$ openstack server create --flavor <flavor> --network <network_name> --security-group <name_of_sc> --image <snapshot_name> --key-name <keypair_name> <name_your_instance>
You can check the status of your newly launched server 
$ openstack server list

Conclusion

You now learned how to upload your custom images using the CLI tools and launch an instance.
