Looking at some old pipeline code of mine, it seems pretty clear that the
"sshagent" wrapper is what you need to use. That takes a "credentials"
property that refers to the credentials object stored in Jenkins, referring
to the private key. Within that block, you can have a "sh" step calling
ssh, which doesn't have to specify any credentials.

Thanks David, I'm sure you're probably right but I've found so many 
different versions of what the 'simple' answer is that I have no real idea 
of the correct syntax for the command.  Referencing credentials that are 
already stored within the Jenkins store, for example; some say this is 
necessary, some say not, and all have different angles on how this should 
be specified.  Even the plugin page isn't really clear on the correct 
syntax, hence my question here.

thanks

I might be missing something simple, but I would think you'd just use the
"sh" pipeline step and run "ssh" with the remote command line to run.
