# chef-solo-search
[![Build Status](https://travis-ci.org/edelight/chef-solo-search.png?branch=master)](https://travis-ci.org/edelight/chef-solo-search)
Chef-solo-search is a cookbook library that adds data bag search powers
to Chef Solo. Data bag support was added to Chef Solo by Chef 0.10.4.
Please see *Supported queries* for a list of query types which are supported.
## Requirements
* ruby >= 1.8
* ruby-chef >= 0.10.4
## Installation
Install this cookbook into your Chef repository using your favorite cookbook
management tool
([Librarian](https://github.com/applicationsonline/librarian-chef),
[Berkshelf](https://github.com/RiotGames/berkshelf), knife...).
In Chef 11, you must either add this to the run list of the nodes where it's used or include it as a dependency in the recipes that use it. [See changes in Chef 11.](http://docs.opscode.com/breaking_changes_chef_11.html#non-recipe-file-evaluation-includes-dependencies)
Now you have to make sure chef-solo knows about data bags, therefore add
data_bag_path "<node_work_path>/data_bags"
to the config file of chef-solo (defaults to /etc/chef/solo.rb).
The same for your roles, add
role_path "<node_work_path>/roles"
## Supported queries
The search methods supports a basic sub-set of the lucene query language.
Sample supported queries are:
### General queries:
search(:users, "*:*")
search(:users)
search(:users, nil)
getting all items in ':users'
search(:users, "username:*")
search(:users, "username:[* TO *]")
getting all items from ':users' which have a 'username' attribute
search(:users, "(NOT username:*)")
search(:users, "(NOT username:[* TO *])")
getting all items from ':users' which don't have a 'username' attribute
### Queries on attributes with string values:
search(:users, "username:speedy")
getting all items from ':users' with username equals 'speedy'
search(:users, "NOT username:speedy")
getting all items from ':users' with username is unequal to 'speedy'
search(:users, "username:spe*")
getting all items which 'username'-value begins with 'spe'
### Queries on attributes with array values:
search(:users, "children:tom")
getting all items which 'children' attribute contains 'tom'
search(:users, "children:t*")
getting all items which have at least one element in 'children'
which starts with 't'
### Queries on attributes with boolean values:
search(:users, "married:true")
### Queries in attributes with integer values:
search(:users, "age:35")
### OR conditions in queries:
search(:users, "age:42 OR age:22")
### AND conditions in queries:
search(:users, "married:true AND age:35")
### NOT condition in queries:
search(:users, "children:tom NOT gender:female")
### More complex queries:
search(:users, "children:tom NOT gender:female AND age:42")
## Supported Objects
The search methods have support for 'roles', 'nodes' and 'databags'.
### Roles
You can use the standard role objects in json form and put them into your role path
{
"name": "monitoring",
"default_attributes": { },
"override_attributes": { },
"json_class": "Chef::Role",
"description": "This is just a monitoring role, no big deal.",
"run_list": [
],
"chef_type": "role"
### Nodes
Nodes are injected through a databag called 'node'. Create a databag called 'node' and put your json files there
You can use the standard node objects in json form.
{
"id": "vagrant",
"name": "vagrant-vm",
"chef_environment": "_default",
"json_class": "Chef::Node",
"automatic": {
"hostname": "vagrant.vm",
"os": "centos"
},
"normal": {
},
"chef_type": "node",
"default": {
},
"override": {
},
"run_list": [
"role[monitoring]"
]
}
### Databags
You can use the standard databag objects in json form
{
"id": "my-ssh",
"hostgroup_name": "all",
"command_line": "$USER1$/check_ssh $HOSTADDRESS$"
}
## Running tests
Running tests is as simple as:
% rake test
