KNIFE-SEARCH(1) knife search KNIFE-SEARCH(1)

NAME

knife-search - The man page for the knife search subcommand.
Search indexes allow queries to be made for any type of data that is indexed by the Chef server, including data bags (and data bag items), environments, nodes, and roles. A defined query syntax is used to support search patterns like exact, wildcard, range, and fuzzy. A search is a full-text query that can be done from several locations, including from within a recipe, by using the search subcommand in knife, the search method in the Recipe DSL, and by using the /search or /search/INDEX endpoints in the Chef server API. The search engine is based on Apache Solr and is run from the Chef server.
The knife search subcommand is used run a search query for information that is indexed on a Chef server.
Syntax
This subcommand has the following syntax:
$ knife search INDEX SEARCH_QUERY


where INDEX is one of client, environment, node, role, or the name of a data bag and SEARCH_QUERY is the search query syntax for the query that will be executed.
INDEX is implied if omitted, and will default to node. For example:
$ knife search '*:*' -i


will return something similar to:
8 items found
centos-62-dev opensuse-1203 ubuntu-1304-dev ubuntu-1304-orgtest ubuntu-1204-ohai-test ubuntu-1304-ifcfg-test ohai-test win2k8-dev


and is the same search as:
$ knife search node '*:*" -i


If the SEARCH_QUERY does not contain a colon character (:), then the default query pattern is tags:*#{@query}* OR roles:*#{@query}* OR fqdn:*#{@query}* OR addresses:*#{@query}*, which means the following two search queries are effectively the same:
$ knife search ubuntu


or:
$ knife search node "tags:*ubuntu* OR roles:*ubuntu* OR fqdn:*ubuntu* (etc.)"

-a ATTR, --attribute ATTR

-h, --help
Shows help for the command.
-i, --id-only

-o SORT, --sort SORT
The order in which search results will be sorted.
--print-after

-R INT, --rows INT
The number of rows to be returned.
-s URL, --server-url URL

-v, --version
The version of the chef-client.
-V, --verbose

-y, --yes

-z, --local-mode

Examples
To search for the IDs of all nodes running on the Amazon EC2 platform, enter:
$ knife search node 'ec2:*' -i


to return something like:
4 items found
ip-0A7CA19F.ec2.internal
ip-0A58CF8E.ec2.internal
ip-0A58E134.ec2.internal
ip-0A7CFFD5.ec2.internal


To search for the instance type (flavor) of all nodes running on the Amazon EC2 platform, enter:
$ knife search node 'ec2:*' -a ec2.instance_type


to return something like:
4 items found
ec2.instance_type: m1.large id: ip-0A7CA19F.ec2.internal
ec2.instance_type: m1.large id: ip-0A58CF8E.ec2.internal
ec2.instance_type: m1.large id: ip-0A58E134.ec2.internal
ec2.instance_type: m1.large id: ip-0A7CFFD5.ec2.internal


To search for all nodes running Ubuntu, enter:
$ knife search node 'platform:ubuntu'


To search for all nodes running CentOS in the production environment, enter:
$ knife search node 'chef_environment:production AND platform:centos'


To find a nested attribute, use a pattern similar to the following:
$ knife search node <query_to_run> -a <main_attribute>.<nested_attribute>


To build a search query to use more than one attribute, use an underscore ( _) to separate each attribute. For example, the following query will search for all nodes running a specific version of Ruby:
$ knife search node "languages_ruby_version:1.9.3"


To build a search query that can find a nested attribute:
$ knife search node name:<node_name> -a kernel.machine


To test a search query that will be used in a knife ssh command:
$ knife search node "role:web NOT name:web03"


where the query in the previous example will search all servers that have the web role, but not on the server named web03.
