Mat,
This should work (untested):
file { "/tmp/server_binary":
source => "puppet:///files/server_binary",
notify => Exec["stop-server"];
}
file { "/usr/local/sbin/server_binary":
source => "/tmp/server_binary",
require => Exec["stop-server"],
notify => Exec["start-server"]
}
# Stops the server
exec { "/usr/local/sbin/stop-server":
alias => "stop-server",
refreshonly => true
}
# Starts the server
exec { "/usr/local/sbin/start-server":
alias => "start-server",
refreshonly => true
}
