Package bootfromvolume extends a server create request with the ability to
specify block device options. This can be used to boot a server from a block
storage volume as well as specify multiple ephemeral disks upon creation.
It is recommended to refer to the Block Device Mapping documentation to see
all possible ways to configure a server's block devices at creation time:
https://docs.openstack.org/nova/latest/user/block-device-mapping.html
Note that this package implements `block_device_mapping_v2`.
Example of Creating a Server From an Image
This example will boot a server from an image and use a standard ephemeral
disk as the server's root disk. This is virtually no different than creating
a server without using block device mappings.
blockDevices := []bootfromvolume.BlockDevice{
bootfromvolume.BlockDevice{
BootIndex: 0,
DeleteOnTermination: true,
DestinationType: bootfromvolume.DestinationLocal,
SourceType: bootfromvolume.SourceImage,
UUID: "image-uuid",
},
}
serverCreateOpts := servers.CreateOpts{
Name: "server_name",
FlavorRef: "flavor-uuid",
ImageRef: "image-uuid",
}
createOpts := bootfromvolume.CreateOptsExt{
CreateOptsBuilder: serverCreateOpts,
BlockDevice: blockDevices,
}
server, err := bootfromvolume.Create(client, createOpts).Extract()
if err != nil {
panic(err)
}
Example of Creating a Server From a New Volume
This example will create a block storage volume based on the given Image. The
server will use this volume as its root disk.
blockDevices := []bootfromvolume.BlockDevice{
bootfromvolume.BlockDevice{
DeleteOnTermination: true,
DestinationType: bootfromvolume.DestinationVolume,
SourceType: bootfromvolume.SourceImage,
UUID: "image-uuid",
VolumeSize: 2,
},
}
serverCreateOpts := servers.CreateOpts{
Name: "server_name",
FlavorRef: "flavor-uuid",
}
createOpts := bootfromvolume.CreateOptsExt{
CreateOptsBuilder: serverCreateOpts,
BlockDevice: blockDevices,
}
server, err := bootfromvolume.Create(client, createOpts).Extract()
if err != nil {
panic(err)
}
Example of Creating a Server From an Existing Volume
This example will create a server with an existing volume as its root disk.
blockDevices := []bootfromvolume.BlockDevice{
bootfromvolume.BlockDevice{
DeleteOnTermination: true,
DestinationType: bootfromvolume.DestinationVolume,
SourceType: bootfromvolume.SourceVolume,
UUID: "volume-uuid",
},
}
serverCreateOpts := servers.CreateOpts{
Name: "server_name",
FlavorRef: "flavor-uuid",
}
createOpts := bootfromvolume.CreateOptsExt{
CreateOptsBuilder: serverCreateOpts,
BlockDevice: blockDevices,
}
server, err := bootfromvolume.Create(client, createOpts).Extract()
if err != nil {
panic(err)
}
Example of Creating a Server with Multiple Ephemeral Disks
This example will create a server with multiple ephemeral disks. The first
block device will be based off of an existing Image. Each additional
ephemeral disks must have an index of -1.
blockDevices := []bootfromvolume.BlockDevice{
bootfromvolume.BlockDevice{
BootIndex: 0,
DestinationType: bootfromvolume.DestinationLocal,
DeleteOnTermination: true,
SourceType: bootfromvolume.SourceImage,
UUID: "image-uuid",
VolumeSize: 5,
},
bootfromvolume.BlockDevice{
BootIndex: -1,
DestinationType: bootfromvolume.DestinationLocal,
DeleteOnTermination: true,
GuestFormat: "ext4",
SourceType: bootfromvolume.SourceBlank,
VolumeSize: 1,
},
bootfromvolume.BlockDevice{
BootIndex: -1,
DestinationType: bootfromvolume.DestinationLocal,
DeleteOnTermination: true,
GuestFormat: "ext4",
SourceType: bootfromvolume.SourceBlank,
VolumeSize: 1,
},
}
serverCreateOpts := servers.CreateOpts{
Name: "server_name",
FlavorRef: "flavor-uuid",
ImageRef: "image-uuid",
}
createOpts := bootfromvolume.CreateOptsExt{
CreateOptsBuilder: serverCreateOpts,
BlockDevice: blockDevices,
}
server, err := bootfromvolume.Create(client, createOpts).Extract()
if err != nil {
panic(err)
}
