Hi Folks, I've been hacking away at creating an automated deployment system for Swift using Chef. I'd like to drop a design idea on you folks (most of which I've already implemented) and get feedback from this esteemed group.
My end goal is to have a "manifest" (apologies to Puppet) which will define an entire swift cluster, deploy it automatically, and allow edits to the ingredients to manage the cluster. In this case, a "manifest" is a combination of a chef databag describing the swift settings, and a spiceweasel infrastructure.yaml file describing the OS configuration. Ingredients: - swift cookbook with base, proxy and server recipes. proxy nodes also (provisionally) contain auth services. storage nodes handle object, container and account services. -- Base recipe handles common package install, OS user creation. Sets up keys. -- Proxy recipe handles proxy nodes: network config, package install, memcache config, proxy and auth package config, user creation, ring management (including builder file backup), user management -- Storage recipe handles storage nodes: network config, storage device config, package install, ring management. - chef databag that describes a swift cluster (eg: mycluster_databag.json) -- proxy config settings -- memcached settings -- settings for all rings and devices -- basic user settings -- account management - chef "spiceweasel" file that auto-vivifies the infrastructure: (eg: mycluster_infra.yaml) -- uploads cookbooks -- uploads roles -- uploads the cluster's databag -- kicks off node provisioning by requesting from infrastructure API (ec2 or what have you) the following: --- chef roles applied (role[swift:proxy] or role[swift:storage]) --- server flavor --- storage device configs --- hostname --- proxy and storage network details By calling this spiceweasel file, the infrastructure can leap into existence. I'm more or less done with all this stuff - and I'd really appreciate conceptual feedback before I take out all the non-sense code I have in the files and publish. Many thanks! Happy spring, northern hemispherians! -judd Judd Maltin T: 917-882-1270 F: 501-694-7809 A loving heart is never wrong.
