Dear all, We are thinking about the possibility of using Puppet in an image-based cluster. The compute nodes would boot and load the whole image to a ramdisk, where r/w access is granted afterwards.
Our idea is to have a sample compute node running puppet where to create the image from, and periodically extract a new image from it. Nodes that reboot, simply take that image, change the hostname and IP addresses, and little more (typical in image-based systems). The nice thing about this is that, since the source image is from a puppetized host, its clones will be as well! So changes in the puppet configuration will be applied immediately to the nodes. Does it sound right? I currently foresee a problem with the puppet node certificates: is it possible to use a generic certificate, to enable trust between puppet server and clients, but having each node a different fqdn and be treated by puppet as different hosts (including PuppetDB entries)? I saw different facts for each: ::clientcert and ::fqdn, that gave me hopes. Besides that, do you see any other problem with this type of deployment? Does anybody have experience with something similar? Thanks! BR/Pablo -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
