Class HardcodeLocalhostAsNodeMetadataSupplier

java.lang.Object

com.google.inject.AbstractModule

org.jclouds.virtualbox.config.HardcodeLocalhostAsNodeMetadataSupplier

All Implemented Interfaces:

com.google.inject.Module

public class HardcodeLocalhostAsNodeMetadataSupplier
extends com.google.inject.AbstractModule

In particular, this binds Supplier<NodeMetadata> so that it can be used in ssh commands. Ssh is necessary for operations that cannot be performed in the virtual box api, such as clearing sessions. ex. once this is loaded, use Guice to inject Supplier<NodeMetadata> as host and RunScriptOnNode#Factory as factory, to start making commands like the following:

 import static org.jclouds.compute.options.RunScriptOptions.Builder.runAsRoot;
 import static org.jclouds.scriptbuilder.domain.Statements.*;
 
    ...
  
  // direct execute a script as opposed to using sudo, or an init wrapper
  ListenableFuture fooInTheFuture = factory.submit(host.get(), 
          exec("echo foo"), runAsRoot(false).wrapInInitScript(false));
 
  ExecResponse foo = Futures.getUnchecked(fooInTheFuture);
 
  // call a set of commands that are defined in classpath/functions/function_name.sh
  ListenableFuture kill = factory.submit(host.get(), 
          call("killsession"), runAsRoot(false).wrapInInitScript(false));
 
 ...
 
 

Note

People often forget to call Future.get() when using RunScriptOnNode.Factory#submit. Don't forget!
