Class EagerNodePoolComputeServiceAdapter

java.lang.Object

org.jclouds.nodepool.internal.BaseNodePoolComputeServiceAdapter

org.jclouds.nodepool.internal.EagerNodePoolComputeServiceAdapter

All Implemented Interfaces:

ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>, JCloudsNativeComputeServiceAdapter, NodePoolComputeServiceAdapter

@Singleton
public class EagerNodePoolComputeServiceAdapter
extends BaseNodePoolComputeServiceAdapter

An eager NodePoolComputeService. Eagerly builds and maintains a pool of nodes. It's only "started" after min nodes are allocated and available.

Description copied from interface: ComputeServiceAdapter

ComputeService.createNodesInGroup(String, int, Template) generates the parameters passed into this method such that each node in the set has a unique name.

note

It is intentional to return the library native node object, as generic type N. If you are not using library-native objects (such as libvirt Domain) use JCloudsNativeComputeServiceAdapter instead.

note

Your responsibility is to create a node with the underlying library and return after storing its credentials in the supplied map corresponding to credentialStore

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
