Teyo, Bruce, and I were bouncing around some ideas resently for an simple but enhanced puppetrun.
Basically the idea is merging the ideas behind Func and Puppetrun. Obviously other tools like mcollective have various other advantaged features so this will be fairly primative by comparison, though it won't require a message bus. If you want something more advanced obviously try out those tools, this is covering a much smaller use case. This is something I am going to take a crack at this in the coming weeks. This would be something pretty simple and lightweight, and could probably fix a lot of the use cases around making puppetrun (or staggering large sets of hosts) a lot easier. Features I'm thinking of: Requires no additonal ports, setup, or config files -- use existing puppet listening capability and puppetca, just a /usr/bin app Be able to query dashboard DB to run against tagged nodes or hosts that have certain data there (or in storeconfigs???) Be able to run against wildcarded nodes based on what certs are present on the puppetmaster (we know the hostnames) Be able to be used easily from an API perspective from any ruby application Be able to invoke ralsh remotely for querying things (and for debug, and one off tasks) Be able to run shell commands for things that are one offs (emergency security power down now) Example syntax: punc --hosts *.example.org --puppetize # get new catalog and run punc --hosts *.example.org --ralsh "service name=foo ensure=running" # perform an action through ralsh punc --hosts *.example.org --shell "/bin/emergency_script" # run a shell script... for the one-off cases punc --hosts foo.*.example.org --ralsh "service name=foo" --format=json # query something with ralsh and generate a report punc --hosts foo.*.example.org --facter fact --format=json # similarly generate a facter report punc --tags webservers [...ditto...] punc --critiera "fact==foo" [..ditto...] punc --critiera "fact==foo" [some operation to run only if fact matches] [...ditto...] So for example we could choose to reboot all the servers that match a given fact, etc. It should also allow easier staged deployments and environment usage from apps that want to use the API.
