I was reading about pallet here: http://twoguysarguing.wordpress.com/2010/11/01/starting-a-cluster-on-ec2-with-pallet/, as well as on the pallet site: http://palletops.com/. I'm still a little confused. The examples are arranged as if I'm expected to enter the code at a REPL.
But I think I'm missing something. Because I feel like (or I'm hoping) there should be some sort of lein support/integration, so that I can define some code to spin up a cluster, start the cluster, stop the cluster, deploy a war file, etc. via a series of lein commands.
I did find the following project on github, but it appears to be written to work with maven instead of lein: https://github.com/cemerick/clojure-web-deploy-conj.
And, this is very close to what I want, except that I want this tied into lein targets somehow: http://cemerick.com/2010/05/12/provisioning-administration-and-deployment-of-couchdb-java-tomcat/.
The Leiningen wiki refers to pallet/pallet-lein.
I don't have any experience with pallet, but it looks like the Leiningen plugin passes the first plugin argument to a function in the pallet.main namespace which appears to call into pallet.
So, the argument foo in lein pallet foo would be passed along to pallet.
