在Ruby中使用RegEx的if语句（首席配方）

Question

I have a Chef recipe in which I'm trying to say:

"If the server's hostname ends in -1, then enable and start the newrelic-sysmond and newrelic-daemon services, else, disable those services"

using RegEx to determine whether the hostname does end in -1 or not.

Using my attempt below, the services seem to enable and start regardless of whether the hostname ends in -1 or not. I'm quite new to Ruby and Chef so I wouldn't be surprise if my code is incorrect:

if node["hostname"] =~ /^.*-1$/
    service 'newrelic-sysmond' do
        action [ :enable, :start ]
    end
    service 'newrelic-daemon' do
        action [ :enable, :start ]
    end
else
    service 'newrelic-sysmond' do
        action [ :disable ]
    end
    service 'newrelic-daemon' do
        action [ :disable ]
    end
end

There is a chance that the hostname isn't what you think it is. You probably want something like if node['machinename'] =~ /-1$/ or if node['machinename'].end_with?('-1') . Otherwise that looks okay.
