You could write your own predicate that does a cast. See
ClusterController.runningInGroup() for something similar.

Pulled the code from RunScriptCommand as an example, and I think I'm good in
that respect.
I'm having issues with runScriptOnNodesMatching() when I want to only run
the script on 1 node in the group. I have the node Id of the target node,
but not sure how to create a predicate that just targets one node based on
the Id. NodePredicates.withIds() returns a PredicateComputeMetadata,
but runScriptOnNodesMatching takes a PredicateNodeMetadata.
The jclouds wiki states Individual commands are executed against a specific
node's id, but that doesnt really explain how to do this.

Take a look at the RunScriptCommand class.
You need to call the function somehow like this:
StatementBuilder builder = new StatementBuilder();
builder.addStatements(
Statements.appendFile(/tmp/my.cfg, lines),
exec(getFileContent(scriptPath))
);
controller.runScriptOnNodesMatching(
spec, condition, builder)

I looked at computeService.runScriptOnNodesMatching a while ago and
couldnt
make much sense on how to use the API correctly (for uploading a script
and
running it). Is there a good unit tests that shows how to do this?

You could also try to use computeService.runScriptOnNodesMatching and
upload the file using an AppendFile jclouds statement together with
the credentials from the cluster spec file.
This approach is similar to what RunScriptCommand is doing.

I'm

copy
the
file to a different folder, via SshClient.exec method. But the
cp

requires sudo because the user whirr created for me doesn't
have
privs to
copy to the required folder. Also, I cant specify a password
with
the
sudo
command because the connection was made using x509
certificates.
So how can I execute remote ssh commands that require sudo
privs?
