Modifier and Type	Method and Description
protected com.google.common.util.concurrent.ListenableFuture<AtomicReference<NodeMetadata>>	createNodeInGroupWithNameAndTemplate(String group, String name, Template template) This calls logic necessary to create a node and convert it from its provider-specific object to the jclouds NodeMetadata object.

protected Set<String>	getNextNames(String group, Template template, int count) Find the next node names that can be used.

execute

public Map<?,com.google.common.util.concurrent.ListenableFuture<Void>> execute(String group,
                                                                      int count,
                                                                      Template template,
                                                                      Set<NodeMetadata> goodNodes,
                                                                      Map<NodeMetadata,Exception> badNodes,

This implementation gets a list of acceptable node names to encode the group into, then it simultaneously runs the nodes and applies options to them.

execute in interface CreateNodesInGroupThenAddToSet

createNodeInGroupWithNameAndTemplate

protected com.google.common.util.concurrent.ListenableFuture<AtomicReference<NodeMetadata>> createNodeInGroupWithNameAndTemplate(String group,
                                                                                                                     String name,
                                                                                                                     Template template)

This calls logic necessary to create a node and convert it from its provider-specific object to the jclouds NodeMetadata object. This call directly precedes customization, such as executing scripts.

The outcome of this operation does not imply the node is running. If you want to insert logic after the node is created, yet before an attempt to customize the node, then append your behaviour to this method. ex. to attach an ip address post-creation

 @Override
 protected ListenableFuture<AtomicReference<NodeMetadata>> createNodeInGroupWithNameAndTemplate(String group, String name,
          Template template) {
 
    ListenableFuture<AtomicReference<NodeMetadata>> future = super.addNodeIntoGroupWithNameAndTemplate(group, name, template);
    return Futures.compose(future, new Function<AtomicReference<NodeMetadata>, AtomicReference<NodeMetadata>>() {
 
       @Override
       public AtomicReference<NodeMetadata> apply(AtomicReference<NodeMetadata> input) {
          NodeMetadata node = input.get();
          // allocate and attach an ip
          input.set(NodeMetadataBuilder.fromNodeMetadata(node).publicAddresses(ImmutableSet.of(ip.getIp())).build());
          return input;
       }
 
    }, executor);
 }
 

Parameters:

group - group the node belongs to

name - generated name of the node

template - user-specified template

Returns:

node that is created, yet not necessarily in NodeMetadata.Status.RUNNING

getNextNames

protected Set<String> getNextNames(String group,
                       Template template,
                       int count)

Find the next node names that can be used. These will be derived from the group and the template. We will pre-allocate a specified quantity, and attempt to verify that there is no name conflict with the current service.

Parameters:

group -

count -

template -

Returns:
