Custom Images

In addition to the default images provided by Wavestack, customers have the flexibility to upload and use their own custom images for instance deployment, offering greater flexibility and customization to meet specific project needs.

Uploading Custom Images via OpenStack CLI

To upload your own private image using the OpenStack CLI, follow these steps:

Prepare the Image: Ensure the image file is in a compatible format, such as QCOW2 or RAW. If necessary, convert the image to the desired format.
Authenticate: Source your OpenStack RC file to authenticate:
```
source /path/to/your-openrc.sh
```
Upload the Image: Use the openstack image create command to upload the image:
```
openstack image create "YourImageName" \
  --file /path/to/your-image-file.qcow2 \
  --disk-format qcow2 \
  --container-format bare
```
- Replace "YourImageName" with the desired name for your image.
- Replace /path/to/your-image-file.qcow2 with the path to your image file.
- Adjust the --disk-format and --container-format if you’re using a different format.
Verify the Upload: Check that your image was successfully uploaded:
```
openstack image list
```
Your custom image should now appear in the list and be ready for use in instance deployment.
