Sorry, just made a typo '/', it should be '\'.

After replaced '/' with '//', I finally got the chef search function work.

I tried the cmd but still no expected result:

0 items found

When I tried the command as below, I can get my ideal result:
~]# knife search node 'run_list:role\[os-controller\]'
1 items found

Node Name:   centos-10-145-88-152
Environment: testing
FQDN:       
IP:          10.145.88.152
Run List:    recipe[keepalived], recipe[haproxy::tcp_lb], role[os-controller]
Roles:      
Recipes:     keepalived, haproxy::tcp_lb, keepalived::default, haproxy::install_package
Platform:    centos 6.5

~]#

So I used it in my cookbook:
pool_members = search(:node, "run_list:role\[#{service['role']}\] AND chef_environment:#{node.chef_environment}") || []

When I run it, I got the error as follow:

It is weird for me, if someone can point it out and share some experience, I will be much appreciated.

Thanks,

Hi Ranjib,

Thank you for your explanation.

If that is my case, do you have any idea to solve the problem?

Thanks,

Sam

chef saves a two computed attributes, aka recipes and roles as part of run list expansion. so, you want to search against 'roles:foo' (plural). 

also some thing in your recipes sets an attribute (may be nested) 'role' , which might explains the first hit.

something like:

node[:a][:role] = 1,

Hi,

I want to get a node list with role[os-controller] in it's run list, so I tried "knife search" command at my chef server CML however I got a weird result as follow:
~]# knife search node role:os-controller
2 items found

In my understanding, chef server should only return one node info with role[os-controller] (here is centos-10-145-88-152), but it return two nodes. I have no idea how to figure it out.

If someone can point it out, it will be much appreciated.

Thanks,
