Provider Interface​

The provider package defines a common contract for all infrastructure backends.

type Provider interface {
    Name() string
    ListPlans(ctx context.Context) ([]Plan, error)
    ProvisionServer(ctx context.Context, plan Plan, name, image, orchestratorDID string) (*Server, error)
    DeleteServer(ctx context.Context, serverID string) error
    RestartServer(ctx context.Context, serverID string) error
    GetServerStatus(ctx context.Context, serverID string) (*Server, error)
    SelectMatchingPlan(plans []Plan, target types.Resources) (*Plan, error)
}

Local Incus Provider​

LocalIncusProvider in the provider directory, is a concrete implementation of Provider that manages local virtual machines using Incus. This way we can locally run and test the on demand provisioning/promise bid logic

Run the logic​

Prepare incus first, and download a vm image:

first run a vm to download an image:

incus launch images:ubuntu/24.04/cloud v2 --vm

then list

incus image list

then create an alias: (replace 2658fb357103 with what you see)

 incus image alias create ubuntu-22.04-vm 2658fb357103

run incus web ui and stop and delete any running vm:

incus webui

Run dms as a gateway by the following config:

general:
  compute_gateway: true
  providers:
    - name: local-incus
      type: local-incus
      config: {}

do a normal deployment

Run e2e tests​

Just run make e2e-DeployWithOnDemandProvisioner and check the incus webui.

Once the online shell is available you can go and check the logs inside /root

You will be able to see the deployment being done
