<h2 id="NAME">NAME</h2>
<p class="man-name">
<code>knife-node</code> - <span class="man-whatis">Manage the hosts in your infrastructure</span>
</p>
<h2 id="SYNOPSIS">SYNOPSIS</h2>
<p><strong>knife</strong> <strong>node</strong> <em>sub-command</em> <em>(options)</em></p>
<h2 id="DESCRIPTION">DESCRIPTION</h2>
<p>Nodes are data structures that represent hosts configured with Chef.
Nodes have a <strong>name</strong>, a String that uniquely identifies the node,
<strong>attributes</strong>, a nested Hash of properties that describe how the host
should be configured, a <strong>chef_environment</strong>, a String representing the
environment to which the node belongs, and a <strong>run_list</strong>, an ordered
list of <strong>recipes</strong> or <strong>roles</strong> that chef-client should apply when
configuring a host.</p>
<p>When a host communicates with a Chef Server, it authenticates using its
<strong>node_name</strong> for identification and signs its reqests with a private
key. The Server validates the request by looking up a <strong>client</strong> object
with a name identical to the <strong>node_name</strong> submitted with the request
and verifes the signature using the public key for that <strong>client</strong>
object. <strong>NOTE</strong> that the <strong>client</strong> is a different object in the
system. It is associated with a node by virtue of having a matching
name.</p>
<p>By default <strong>chef-client</strong>(8) will create a node using the FQDN of the
host for the node name, though this may be overridden by configuration
settings.</p>
<h2 id="NODE-SUB-COMMANDS">NODE SUB-COMMANDS</h2>
<p>The following <code>node</code> subcommands are available:</p>
<h2 id="BULK-DELETE">BULK DELETE</h2>
<p><strong>knife node bulk delete</strong> <em>regex</em> <em>(options)</em></p>
<p>Deletes nodes for which the name matches the regular expression <em>regex</em>
on the Chef Server. The regular expression should be given in quotes,
and should not be surrounded with forward slashes (as is typical of
regular expression literals in scripting languages).</p>
<h2 id="CREATE">CREATE</h2>
<p><strong>knife node create</strong> <em>name</em> <em>(options)</em></p>
<p>Create a new node. Unless the --disable-editing option is given, an empty node
object will be created and displayed in your text editor. If the editor
exits with a successful exit status, the node data will be posted to the
Chef Server to create the node.</p>
<h2 id="DELETE">DELETE</h2>
<p><strong>knife node delete</strong> <em>name</em> <em>(options)</em></p>
<p>Deletes the node identified by <em>name</em> on the Chef Server.</p>
<h2 id="EDIT">EDIT</h2>
<p><strong>knife node edit</strong> <em>name</em> <em>(options)</em></p>
<dl>
<dt><code>-a</code>, <code>--all</code></dt><dd>Display all node data in the editor. By default, default, override,
and automatic attributes are not shown.</dd>
</dl>
<p>Edit the node identified by <em>name</em>. Like <strong>knife node create</strong>, the node
will be displayed in your text editor unless the -n option is present.</p>
<h2 id="FROM-FILE">FROM FILE</h2>
<p><strong>knife node from file</strong> <em>file</em> <em>(options)</em></p>
<p>Create a node from a JSON format <em>file</em>.</p>
<h2 id="LIST">LIST</h2>
<p><strong>knife node list</strong> <em>(options)</em></p>
<dl>
<dt><code>-w</code>, <code>--with-uri</code></dt><dd>Show corresponding URIs</dd>
</dl>
<p>List all nodes.</p>
<h2 id="RUN_LIST-ADD">RUN_LIST ADD</h2>
<p><strong>knife node run_list add</strong> <em>name</em> <em>run list item</em> <em>(options)</em></p>
<dl>
<dt><code>-a</code>, <code>--after ITEM</code></dt><dd>Place the ENTRY in the run list after ITEM</dd>
</dl>
<p>Add the <em>run list item</em> to the node's <code>run_list</code>. See Run list</p>
<h2 id="RUN_LIST-REMOVE">RUN_LIST REMOVE</h2>
<p><strong>knife node run_list remove</strong> <em>node name</em> <em>run list item</em> <em>(options)</em></p>
<p>Remove the <em>run list item</em> from the node's <code>run_list</code>.</p>
<h2 id="SHOW">SHOW</h2>
<p><strong>knife node show</strong> <em>node name</em> <em>(options)</em></p>
<dl>
<dt><code>-a</code>, <code>--attribute [ATTR]</code></dt><dd>Show only one attribute</dd>
<dt><code>-r</code>, <code>--run-list </code></dt><dd>Show only the run list</dd>
<dt><code>-F</code>, <code>--format FORMAT</code></dt><dd>Display the node in a different format.</dd>
<dt><code>-m</code>, <code>--medium</code></dt><dd>Display more, but not all, of the node's data when using the default
<em>summary</em> format</dd>
</dl>
<p>Displays the node identified by <em>node name</em> on stdout.</p>
<h2 id="RUN-LIST-ITEM-FORMAT">RUN LIST ITEM FORMAT</h2>
<p>Run list items may be either roles or recipes. When adding a role to a
run list, the correct syntax is "role[ROLE_NAME]"</p>
<p>When adding a recipe to a run list, there are several valid formats:</p>
<dl>
<dt>Fully Qualified Format</dt><dd>"recipe[COOKBOOK::RECIPE_NAME]", for example, "recipe[chef::client]"</dd>
<dt>Cookbook Recipe Format</dt><dd>For brevity, the recipe part of the fully qualified format may be omitted, and recipes specified as "COOKBOOK::RECIPE_NAME", e.g., "chef::client"</dd>
<dt>Default Recipe Format</dt><dd>When adding the default recipe of a cookbook to a run list, the recipe name may be omitted as well, e.g., "chef::default" may be written as just "chef"</dd>
