Hello! I''ve got a manifest that involves downloading and updating a bunch of different packages using apt, pip, etc. One of my apt-dependencies, dnsmasq<http://www.thekelleys.org.uk/dnsmasq/doc.html>, redirects the machine''s DNS. Any modules currently running at that time that use the internet get a temporary name resolution error. Unfortunately, I can''t run this class in a different stage, as it creates a dependency cycle with the other things that depend on dnsmasq. Is there a way to force puppet to run a particular class by itself? There are enough other tasks/jobs/whatever-we-call-them that being explicit about the dependencies isn''t really worth it (and it''d have to be kept up to date as my manifest grows).

I''ve got a few resources which are applied to bootstrap the whole process, which can be applied separately using "--tags kickstart::bootstrap", which is used while kickstarting the node. This ensures that when it reboots, it has a properly configured puppet, but doesn''t start services in kickstart. Alternatively you can pack the initial installation and configuration of dnsmasq into an exec{} to ensure semi-atomic execution. Not recommended, but possible.

Thanks for your reply! My issue was that my dnsmasq class was a) downloading the package b) setting up the service and c) adding monit monitoring scripts for it. The last part was the cyclic dependency issue. A number of things are monitored by monit, and pulling one of them into my ''preload'' stage involved pulling all the other dependencies, too, which didn''t work. My solution was to split up the dnsmasq class, separating the package download (and initial run) from the rest. I then added this into its own special stage (preload->dnsmasq->main), which solved my problem. I hope this helps future travellers.

Hi David, I don''t suppose you know of any good resources (blog posts or git hub example code) showing this. I am trying to look at a way to kickstart the build of a puppet master and would prefer moving down this path. At the moment I am using a bootstrap script to download forge modules and modules hosted on github then doing a puppet apply from the command line to kickstart. Thanks, Peter.
