[chef] Re: RE: Re: override argument

You can compose your roles such that you apply 'role[base],role[app1],role[app2]' to a server.  The 'base' role may install user accounts, security settings, resolv.conf, logrotation for system logs, etc and other stuff not necessarily directly about running the app.  The application roles should install the prerequisites for the app and deploy the app itself.  In order to immediately deploy 'app1' you can run "chef-client -o 'role[app1]'" which will only run the stuff necessary to deploy app1 and will skip running the rest of the recipes in the base role or for app2.  That will allow chef to complete deploying app1 much faster.

You probably do not want to overuse override run lists.  They're for doing-a-piece-of-the-whole-run-list-right-now, and only doing that occasionally on demand.

HI,

 

Thank you Indra. I am aware of the feature. I am just wondering if it’s safe to use –o or is it really only for testing.

Hi Flo,
 
        Ya, it gets run.
chef-client -o "recipe[something]"
 

the above command runs a chef-client with given runlist .

You can also refer this  by

"chef-client -h"    ---which shows a what are all parameters we can run with chef-client.

Thanks,
Indra

Hi,

 

What is the contract for the –o argument on chef-client? Can I expect that the only thing that changes between running ‘chef-client’ and ‘chef-client –o “recipe[something]”’, is the recipes that will get run?
