Overview

Package attachments provides access to OpenStack Block Storage Attachment API's. Use of this package requires Cinder version 3.27 at a minimum.

For more information, see: https://docs.openstack.org/api-ref/block-storage/v3/index.html#attachments

Example to List Attachments

listOpts := &attachments.ListOpts{
	InstanceID: "uuid",
}

client.Microversion = "3.27"
allPages, err := attachments.List(client, listOpts).AllPages()
if err != nil {
	panic(err)
}

allAttachments, err := attachments.ExtractAttachments(allPages)
if err != nil {
	panic(err)
}

for _, attachment := range allAttachments {
	fmt.Println(attachment)
}

Example to Create Attachment

createOpts := &attachments.CreateOpts{
	InstanceiUUID: "uuid",
	VolumeUUID: "uuid"
}

client.Microversion = "3.27"
attachment, err := attachments.Create(client, createOpts).Extract()
if err != nil {
	panic(err)
}

fmt.Println(attachment)

Example to Get Attachment

client.Microversion = "3.27"
attachment, err := attachments.Get(client, "uuid").Extract()
if err != nil {
	panic(err)
}

fmt.Println(attachment)

Example to Update Attachment

opts := &attachments.UpdateOpts{
	Connector: map[string]interface{}{
		"mode": "ro",
	}
}

client.Microversion = "3.27"
attachment, err := attachments.Update(client, "uuid", opts).Extract()
if err != nil {
	panic(err)
}

fmt.Println(attachment)

Example to Complete Attachment

client.Microversion = "3.44"
err := attachments.Complete(client, "uuid").ExtractErr()
if err != nil {
	panic(err)
}

Example to Delete Attachment

client.Microversion = "3.27"
err := attachments.Delete(client, "uuid").ExtractErr()
if err != nil {
	panic(err)
}
