##Using the Openstack Block Storage provider

BETA - This API may change as additional providers for block storage are added to pkgcloud

Creating a block-storage client is straight-forward:

  var openstack = pkgcloud.blockstorage.createClient({
    provider: 'openstack', // required
    username: 'your-user-name', // required
    password: 'your-password', // required
    authUrl: 'your identity service url' // required
  });

Note: Due to variances between OpenStack deployments, you may or may not need a region option.

Volume Model

A Volume for BlockStorage has following properties:

{
  id: '12345678-1111-2222-3333-123456789012', // id of the volume
  name: 'foo3',
  description: 'my volume',
  status: 'available', // status of the volume
  size: 100, // in GB
  volumeType: 'SATA',
  attachments: [], // array of the attachments for this volume
  snapshotId: null, // snapshotId, if any, for this volume
  createdAt: '2013-07-26T15:54:04.000000'
}

Snapshot Model

A Snapshot for BlockStorage has the following properties:

{
  id: '12345678-1111-2222-3333-123456789012', // id of the snapshot
  name: 'foo3',
  description: 'my snapshot',
  status: 'available', // status of the snapshot
  size: 100, // in GB
  volumeId: '12345678-1111-2222-3333-123456789012',
  createdAt: '2013-07-26T15:54:04.000000'
}

VolumeType Model

A VolumeType for BlockStorage has the following properties:

{
  id: '12345678-1111-2222-3333-123456789012', // id of the snapshot
  name: 'SSD',
  extra_specs: {} // not used presently
}

Volume APIs

client.getVolumes(options, callback)

Lists all volumes that are available to use on your Openstack account

Callback returns f(err, volumes) where volumes is an Array. options is an optional boolean which will return the full volume details if true.

client.getVolume(volume, callback)

Gets specified volume.

Takes volume or volumeId as an argument and returns the volume in the callback f(err, volume)

client.createVolume(details, callback)

Creates a volume with the details specified

Options are as follows:

{
  name: 'volumeName', // required
  description: 'my volume',  // required
  size: 100,    // 100-1000 gb
  volumeType: 'SSD' // optional, defaults to spindles
  snapshotId: '1234567890' // optional, the snapshotId to use when creating the volume
}

Returns the new volume in the callback f(err, volume)

client.deleteVolume(volume, callback)

Deletes the specified volume

Takes volume or volumeId as an argument and returns an error if unsuccessful f(err)

client.updateVolume(volume, callback)

Updates the name & description on the provided volume. Does not support resize.

Returns callback with a confirmation

Snapshot APIs

client.getSnapshots(options, callback)

Lists all snapshots that are available to use on your Openstack account

Callback returns f(err, snapshots) where snapshots is an Array. options is an optional boolean which will return the full snapshot details if true.

client.getSnapshot(snapshot, callback)

Gets specified snapshot.

Takes snapshot or snapshotId as an argument and returns the snapshot in the callback f(err, snapshot)

client.createSnapshot(details, callback)

Creates a snapshot with the details specified

Options are as follows:

{
  name: 'volumeName', // required
  description: 'my volume',  // required
  volumeId: 'asdf1234', // required, volume id of the new snapshot
  force: true // optional, defaults to false. force creation of the snapshot
}

Returns the new snapshot in the callback f(err, snapshot)

client.deleteSnapshot(snapshot, callback)

Deletes the specified snapshot

Takes snapshot or snapshotId as an argument and returns an error if unsuccessful f(err)

client.updateSnapshot(snapshot, callback)

Updates the name & description on the provided snapshot.

Returns callback with a confirmation

VolumeType APIs

Volume types are used to define which kind of new volume to create.

client.getVolumeTypes(callback)

Lists all volumeTypes that are available to use on your Openstack account

Callback returns f(err, volumeTypes) where volumeTypes is an Array.

client.getVolumeType(volumeType, callback)

Gets specified volumeType.

Takes volumeType or volumeTypeId as an argument and returns the volumeType in the callback f(err, volumeType)
