Method Detail

listServers

Set<Server> listServers(ListOptions... options)

List all servers (IDs and names only) This operation provides a list of servers associated with your identity. Servers that have been deleted are not included in this list.

in order to retrieve all details, pass the option withDetails()

getServer

Server getServer(int id)

This operation returns details of the specified server.

Returns:

null, if the server is not found

See Also:

Server

deleteServer

boolean deleteServer(int id)

This operation deletes a cloud server instance from the system.

Note: When a server is deleted, all images created from that server are also removed.

Returns:

false if the server is not found

See Also:

Server

rebootServer

void rebootServer(int id,
                  RebootType rebootType)

The reboot function allows for either a soft or hard reboot of a server.

Status Transition:

ACTIVE - REBOOT - ACTIVE (soft reboot)

ACTIVE - HARD_REBOOT - ACTIVE (hard reboot)

Parameters:

rebootType - With a soft reboot, the operating system is signaled to restart, which allows for a graceful shutdown of all processes. A hard reboot is the equivalent of power cycling the server.

resizeServer

void resizeServer(int id,
                  int flavorId)

The resize function converts an existing server to a different flavor, in essence, scaling the server up or down. The original server is saved for a period of time to allow rollback if there is a problem. All resizes should be tested and explicitly confirmed, at which time the original server is removed. All resizes are automatically confirmed after 24 hours if they are not confirmed or reverted.

Status Transition:

ACTIVE - QUEUE_RESIZE - PREP_RESIZE - VERIFY_RESIZE

ACTIVE - QUEUE_RESIZE - ACTIVE (on error)

confirmResizeServer

void confirmResizeServer(int id)

The resize function converts an existing server to a different flavor, in essence, scaling the server up or down. The original server is saved for a period of time to allow rollback if there is a problem. All resizes should be tested and explicitly confirmed, at which time the original server is removed. All resizes are automatically confirmed after 24 hours if they are not confirmed or reverted.

Status Transition:

VERIFY_RESIZE - ACTIVE

revertResizeServer

void revertResizeServer(int id)

The resize function converts an existing server to a different flavor, in essence, scaling the server up or down. The original server is saved for a period of time to allow rollback if there is a problem. All resizes should be tested and explicitly reverted, at which time the original server is removed. All resizes are automatically reverted after 24 hours if they are not reverted or reverted.

Status Transition:

VERIFY_RESIZE - ACTIVE

createServer

Server createServer(String name,
                    String imageRef,
                    String flavorRef,
                    CreateServerOptions... options)

This operation asynchronously provisions a new server. The progress of this operation depends on several factors including location of the requested image, network i/o, host load, and the selected flavor. The progress of the request can be checked by performing a GET on /server/id, which will return a progress attribute (0-100% completion). A password will be randomly generated for you and returned in the response object. For security reasons, it will not be returned in subsequent GET calls against a given server ID.

Parameters:

options - - used to specify extra files, metadata, or ip parameters during server creation.

rebuildServer

void rebuildServer(int id,
                   RebuildServerOptions... options)

The rebuild function removes all data on the server and replaces it with the specified image. Server ID and IP addresses remain the same.

Status Transition:

ACTIVE - REBUILD - ACTIVE

ACTIVE - REBUILD - ERROR (on error)

Parameters:

options - - imageId is an optional argument. If it is not specified, the server is rebuilt with the original imageId.

changeAdminPass

void changeAdminPass(int id,
                     String adminPass)

This operation allows you to change the administrative password.

Status Transition: ACTIVE - PASSWORD - ACTIVE

renameServer

void renameServer(int id,
                  String newName)

This operation allows you to update the name of the server. This operation changes the name of the server in the OpenStack Nova system and does not change the server host name itself.

Status Transition: ACTIVE - PASSWORD - ACTIVE

listFlavors

Set<Flavor> listFlavors(ListOptions... options)

List available flavors (IDs and names only) in order to retrieve all details, pass the option withDetails()

getFlavor

Flavor getFlavor(int id)

This operation returns details of the specified flavor.

Returns:

null, if the flavor is not found

See Also:

Flavor

listImages

Set<Image> listImages(ListOptions... options)

List available images (IDs and names only) in order to retrieve all details, pass the option withDetails()

getImage

Image getImage(int id)

This operation returns details of the specified image.

Returns:

null, if the image is not found

See Also:

Image

deleteImage

boolean deleteImage(int id)

This operation deletes an image from the system.

Note: Images are immediately removed. Currently, there are no state transitions to track the delete operation.

Returns:

false if the image is not found

See Also:

Image

createImageFromServer

Image createImageFromServer(String imageName,
                            int serverId)

This operation creates a new image for the given server ID. Once complete, a new image will be available that can be used to rebuild or create servers. Specifying the same image name as an existing custom image replaces the image. The image creation status can be queried by performing a GET on /images/id and examining the status and progress attributes. Status Transition:

QUEUED - PREPARING - SAVING - ACTIVE

QUEUED - PREPARING - SAVING - FAILED (on error)

Note: At present, image creation is an asynchronous operation, so coordinating the creation with data quiescence, etc. is currently not possible.

Throws:

ResourceNotFoundException - if the server is not found

getAddresses

Addresses getAddresses(int serverId)

List all server addresses returns empty set if the server doesn't exist

listPublicAddresses

Set<String> listPublicAddresses(int serverId)
