Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

<table>
<tr>
<th>Attribute</th>
<th>Type</th>
<th>Description</th>

<td><tt>['pm2']['version']</tt></td>
<td>String</td>
<td>PM2 node module version to install</td>

<td><tt>latest</tt></td>
</tr>
</table>

Up the chain

The nodejs cookbook uses the following attributes to define the nodejs and npm formats to install - override them for the desired behaviour.

<table>
<tr>
<th>Attribute</th>
<th>Description</th>
</tr>
<tr>
<td><tt>['nodejs']['install_method']</tt></td>
<td>Nodejs install method</td>
</tr>
<tr>
<td><tt>['nodejs']['npm]['install_method']</tt></td>
<td>NPM install method</td>
</tr>
</table>

See the nodejs cookbook for details.

Recipes

default.rb

Installs PM2 as a global node module using a specific version if specified in the default attributes described above.

nodejs.rb

Install nodejs and npm using the nodejs cookbook.

Example

To install PM2:

Add the pm2 cookbook as a dependency:

depends 'pm2'

Include the pm2::default recipe:

include_recipe 'pm2::default'

Providers

pm2_application

The pm2_application provider manages a json configuration file for a node application and controls it with PM2.

It only start processes from a json configuration (located in /etc/pm2/conf.d) and it does not support starting processes by calling the PM2 CLI directly.

Actions

The available actions try to represent some of the PM2 CLI control actions.

<table>
<tr>
<th>Action</th>
<th>Description</th>
<th>Notes</th>
</tr>
<tr>
<td><tt>:deploy</tt></td>
<td>Create a json configuration file for a node application</td>
<td>All configuration files are deployed in <tt>/etc/pm2/conf.d</tt></td>
</tr>
<tr>
<td><tt>:start</tt></td>
<td>Start an application defined as a json file</td>
<td>It does not change the state of a running application - use one of the start_or_restart/start_or_reload methods instead</td>
</tr>
<tr>
<td><tt>:stop</tt></td>
<td>Stop an application</td>
<td>Invokes the PM2 CLI to stop an application by name</td>

</tr>
<tr>
<td><tt>:reload</tt></td>
<td>Reload an application</td>
<td>Invokes the PM2 CLI to reload an application by name only if it is running</td>
</tr>
<tr>

Example

To deploy and start (or restart) a test.js application that lives in /tmp/test.js:

Install PM2 as described in the Recipes example above.

Use the pm2_application provider - most basic example:

pm2_application 'test' do
  script 'test.js'
  cwd '/tmp'
  action [:deploy, :start_or_restart]
end

This will deploy a /etc/pm2/conf.d/test.json configuration file and start/restart the application with PM2.
