Assume a default query key when none provided in `knife zero chef_client QUERY` about knife-zero

[sawanoboly]

hmm... QUERY syntax based on knife search, ssh. It's usage of chef-server/client environment.

https://docs.chef.io/knife_ssh.html
https://docs.chef.io/knife_search.html

If I implement specific usage to knife-zero, then it's getting harder to follow chef-core updates ( and the edge of chef often cases regression ...).

But, I seem to better way to use name or fqdn by default. In that case, there is a need to be careful not to use as a regular expression.

You're right about it diverging from chef-core. Perhaps it would be welcome there. Created a ticket here for discussion: chef/chef#3526

[sawanoboly]

Thank you for create issue to core 😃

bwaha. the label.

[patcon]

fyi this would work for knife zero commands. Feel free to offer feedback:
chef/chef#3536

[sawanoboly]

@patcon great!

I've add below to Gemfile and tested it.

gem 'chef', github: 'patcon/chef', ref: '3526-fuzz-ssh-query'

There are node which is named knife-zero02. It have IP 133.242.xxx.xxx.

$ bundle exec knife node show knife-zero02
Node Name:   knife-zero02
Environment: _default
FQDN:        
IP:          133.242.xxx.xxx
Run List:    
Roles:       
Recipes:     
Platform:    ubuntu 14.04
Tags:        

In this case, I should pass an ipaddress to fuzzy_query.

$ bundle exec knife zero converge 133.242.xxx.xxx -a ipaddress
133.242.xxx.xxx sudo: unable to resolve host knife-zero02

How about include name to fuzzy target?

$ bundle exec knife zero converge knife-zero02 -a ipaddress
FATAL: No nodes returned from search!

I'm down, but it sounds like Lamont thinks this logic should match the search logic, so maybe mention the idea in the chef issue?

Also, I'll make sure to leave it around this time, but I'd recommend against using my feature branches on your master, as my habit is to delete them after merge, and sometimes they break :)
