Maybe he is asking for the ability to have a certain part of a recipe run every single time. Period.

I'm not sure either, but here is how youd do it.

You can put in something like an "execute" resource block (execute, by itself, is not idempotent, and will be run in its entirety, every. single. time.

Also, parts of the recipe that manually modify the attributes will run every single time (They will not be skipped), incase your wanting to update some node/ohai data each time it runs.

chef-client runs *every* recipe in your run list every time. It converges every recipe every time - but then it only executes the parts that need executing. If it tried to reconfigure everything on every run, you'd have a chef-client that's excruciatingly slow, and likely would break all kinds of things (such as restarting services in the middle of the day).

I have a feeling that you are trying to get chef-client to actually execute something every time?

There are two answers to that.

First of all, chef may be the wrong tool for that job. It is not a good replacement for cron or the like.

Secondly, it *can* be done. Simply have the resource depend on some condition that is never true. Or, if your goal is to run the same thing regularly, use chef to install a script into cron.

Sorry, let me ask it differently.

 

I do the following

1.      knife bootstrap a node

2.      knife node run_list add <node> “run_list”

3.      chef-client on node, which converges the cookbooks

 

Normally, re-running chef-client on the node again will not do anything since the cookbooks have already run the first time, meaning I’ll just get an “up-to-date” message

 

My question is, how can I re-run chef-client to make it “act” like I have not done step 3 above the first time?

Assuming you've bootstrapped the node already and assigned it a role, you simply run chef client.

Is there a way to “force” my cookbooks to rerun without bootstrapping my nodes?
