Map<?,Future<Void>>	execute(String group, int count, Template template, Set<NodeMetadata> goodNodes, Map<NodeMetadata,Exception> badNodes, com.google.common.collect.Multimap<NodeMetadata,CustomizationResponse> customizationResponses) 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.

Description copied from class: CreateNodesWithGroupEncodedIntoNameThenAddToSet

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.

Specified by:

execute in interface CreateNodesInGroupThenAddToSet

Overrides:

execute in class CreateNodesWithGroupEncodedIntoNameThenAddToSet

createNodeInGroupWithNameAndTemplate

protected Future<AtomicReference<NodeMetadata>> createNodeInGroupWithNameAndTemplate(String group,
                                                                                     String name,
                                                                                     Template template)

Description copied from class: CreateNodesWithGroupEncodedIntoNameThenAddToSet

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 Future<AtomicReference<NodeMetadata>> createNodeInGroupWithNameAndTemplate(String group, String name,
          Template template) {
 
    Future<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);
 }
 

Overrides:

createNodeInGroupWithNameAndTemplate in class CreateNodesWithGroupEncodedIntoNameThenAddToSet

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
