Hi,
mco puppet --help
says the following for tags;
--tags, --tag TAG Restrict the run to specific tags
>>mco puppet runonce --noop --tags mysql::master
So, it would be correct that this runs over all puppet nodes, except the
Puppet run will only process mysql::master.
--tags doesn't act as a node filter for MCollective.
If you want to filter you puppet run to nodes, only having the class
mysql::master, use this filter;
-C, --wc, --with-class CLASS Match hosts with a certain config
management class
mco puppet runonce --noop --wc mysql::master
