Set the run_list on the node to include the three cookbooks/recipes that you want to run. See http://docs.opscode.com/essentials_node_object_run_lists.html and http://docs.opscode.com/knife_node.html#run-list-add.

Thanks for the help ,

The idea is that I have 5
Recipes I wanted to run on one node but also want a way where I can run 3 out of these 5 if required and not run all 5 all the time

Thanks
Manoj

You can probably setup roles and add all 5 recipe on one role and have 3 recipes on the second role

But both these roles will be added to the node and will be run when I run chef-client

If you want, for just one run, to use a custom run_list, you can use the -o option to chef-client:

-o RunlistItem,RunlistItem...,   Replace current run list with specified items
    --override-runlist

If this is more permanent, code whatever logic determines whether the given recipes need to run into a cookbook:

if should_run_this_recipe?
include_recipe "some_cookbook::some_recipe"
end

Out of curiosity, what's your motivation? Are these recipes slow and you don't want to waste the time?

You would pass -r and pass either one or both roles

Thanks

The Reason is all these roles use the same recipe and are overriding variables , is there a better way to do this ?

Sure,

I have a recipe for deploying war files to jboss , I use war file name and
location to download it from as a parameter in the recipe.
The idea is to override those variables using the roles.
So if i want to deploy a war file abc.war i call the abc role.

Does it make sense ? I am not sure if this is the best way to do it, even i
am not impressed with this since i have to pass the role as a parameter to
chef client every time.

Thanks

You probably want to extract your recipe code to a LWRP so you can just plug the data into it. See here:

http://docs.opscode.com/lwrp_custom_provider.html

Once that's done, you can give each app deployment its own recipe or cookbook.
