VMDisks

A Virtual Machine Disk (VM Disk) is a virtual storage unit used by virtual machines. This disk can be based on a source image or defined with a specific size. The service allows flexible disk configuration to meet the needs of virtual machines.

Configuration Example

Here is a YAML configuration example for a virtual disk using a source image downloaded from HTTP:

apiVersion: apps.cozystack.io/v1alpha1
kind: VMDisk
metadata:
  name: vm-disk-example
spec:
  source:
    http:
      url: "https://download.cirros-cloud.net/0.6.2/cirros-0.6.2-x86_64-disk.img"
  optical: false
  storage: 10Gi
  storageClass: "replicated"

Using the kubeconfig provided by Hikube and this example yaml, saved as a manifest.yaml file, you can easily test the application deployment using the following command:

kubectl apply -f manifest.yaml
