On Puppet 3, I used to use sudo mco puppet runonce -I /hostname-pattern-1/ -I /hostname-pattern-2/ to run Puppet agents on-demand against any node matching one of the hostname patterns.

As of Puppet 5.5.4, MCollective is deprecated, so I can no longer use the mco command.

With Puppet 6, how can I do what I used to be able to do with the mco command?

My server and all my nodes are running Ubuntu 20 (Linux). I'm specifically using Puppet 6.19.1 and Puppet Server 6.14.1.

I know puppet agent -t can be used to run Puppet on-demand, but that has to be done locally on each node, so how can I apply that command (or something equivalent) from the Puppet server to any node matching a pattern?

I know I could hardcode a bunch of hostnames in a Bash script and use SSH to remotely execute the command, but hardcoding hostnames is not as convenient as specifying hostname patterns.

Have you checked choria?

Puppet Bolt might be another alternative, you could write a task to do something more complex, or just run ad-hoc commands

e.g.

bolt command run 'puppet agent -t' --targets servers

You connect bolt to your puppetdb so you won't have to create and update a static inventory
