delete/instances/{id}/volumes/{volumeId}

ParametersExpand Collapse

volumeID string

body InstanceVolumeDetachParams

ID param.Field[string]

Instance ID or name

ReturnsExpand Collapse

type Instance struct{…}

ID string

Auto-generated unique identifier (CUID2 format)

CreatedAt Time

State InstanceState

Instance state:

Created: VMM created but not started (Cloud Hypervisor native)
Running: VM is actively running (Cloud Hypervisor native)
Paused: VM is paused (Cloud Hypervisor native)
Shutdown: VM shut down but VMM exists (Cloud Hypervisor native)
Stopped: No VMM running, no snapshot exists
Standby: No VMM running, snapshot exists (can be restored)
Unknown: Failed to determine state (see state_error for details)

Accepts one of the following:

const InstanceStateCreated InstanceState = "Created"

const InstanceStateRunning InstanceState = "Running"

const InstanceStatePaused InstanceState = "Paused"
