Note that we do not validate extensions here, on basis that ApplyNovaTemplateOptionsCreateNodesWithGroupEncodedIntoNameThenAddToSet has already done so.

Specified by:

createNodeWithGroupEncodedIntoName in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

Parameters:

group - used to aggregate nodes with identical configuration

name - unique supplied name for the node, which has the group encoded into it.

template - includes imageId, locationId, and hardwareId used to resume the instance.

Returns:

library-native representation of a node. TODO: return typed exception on createNodeFailure

ComputeService.createNodesInGroup(String, int, Template)

listHardwareProfiles

public Iterable<FlavorInZone> listHardwareProfiles()

Description copied from interface: ComputeServiceAdapter

Hardware profiles describe available cpu, memory, and disk configurations that can be used to run a node.

To implement this method, return the library native hardware profiles available to the user. These will be used to launch nodes as a part of the template.

Specified by:

listHardwareProfiles in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

Returns:

a non-null iterable of available hardware profiles.

See Also:

ComputeService.listHardwareProfiles()

listImages

public Iterable<ImageInZone> listImages()

Description copied from interface: ComputeServiceAdapter

Images are the available configured operating systems that someone can run a node with.

To implement this method, return the library native images available to the user. These will be used to launch nodes as a part of the template.

Specified by:

listImages in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

Returns:

a non-null iterable of available images.

See Also:

ComputeService.listImages()

listNodes

public Iterable<ServerInZone> listNodes()

Specified by:

listNodes in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

listLocations

public Iterable<Location> listLocations()

Specified by:

listLocations in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

getNode

public ServerInZone getNode(String id)

Specified by:

getNode in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

getImage

public ImageInZone getImage(String id)

Description copied from interface: ComputeServiceAdapter

get a specific image by id

Specified by:

getImage in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

Parameters:

id - ComputeMetadata.getId(), which is not necessarily ComputeMetadata.getProviderId()

Returns:

image or null if not exists.

destroyNode

public void destroyNode(String id)

Specified by:

destroyNode in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

rebootNode

public void rebootNode(String id)

Specified by:

resumeNode

public void resumeNode(String id)

Specified by:

resumeNode in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>

suspendNode

public void suspendNode(String id)

Specified by:

suspendNode in interface ComputeServiceAdapter<ServerInZone,FlavorInZone,ImageInZone,Location>
