Execute a cmd via jclouds SshClient that requires sudo privs on VM
started by Whirr
I've got a cluster that gets started by Whirr. After its running, I need to
create a config file and copy it up to a specific folder on the VM. I'm
using the class.method SshClient.put() to copy the file up to the /tmp
directory on my VM with no security issues. But then I need to copy the
file to a different folder, via SshClient.exec method. But the cp command
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?

Thanks,
John C

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

Posted by John Conwell <jo...@iamjohn.me>.
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
Predicate<ComputeMetadata>, but runScriptOnNodesMatching
takes a Predicate<NodeMetadata>.
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?

Re: Execute a cmd via jclouds SshClient that requires sudo privs on

Posted by Andrei Savu <sa...@gmail.com>.
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.

the AMI is us-east-1/ami-da0cf8b3
