Overview

This module installs the Ghost Blogging Platform.

It's tested and supported on CentOS/RHEL 6 and 7. Ubuntu 12/14 support got dropped because those versions are EOL. The module might still be compatible. Patches for Ubuntu 16/18/20 or other distributions are highly appreciated.

Module Description

This module is intended for Ubuntu. It essentially follows the Linux docs and deployment instructions by using wget to grab the latest Ghost distribution, unzips it, runs npm install --production, configures the config file via a template (if desired), adds a proletaryo/supervisor program to run Ghost, includes puppetlabs/nodejs class, adds the ghost user and group, and finally starts ghost.

Setup

What ghost affects

  • Packages
    • nodejs
    • npm
    • unzip
    • curl
    • supervisor
  • Services
    • supervisor
  • Files
    • /home/ghost/
    • /etc/supervisor/conf.d/ghost_<blog>.conf
  • User
    • ghost
  • Group
    • ghost

Beginning with ghost

The simplest use of this module is:

class { 'ghost':
  include_nodejs => true,
} -> ghost::blog { 'my_blog': }

Ghost Blog Profile

If you just want a working ghost instance, and just want some sensible defaults and hosted by nginx, you can use the ghost_blog_profile. This uses this module and sets up a ghost blog to work end-to-end.

class { 'ghost_blog_profile::basic':
  blog_name => 'my_blog',
}

Here is an alternative Puppet profile for a Ghost blog with Nginx.

class profile::ghost {
  include profile::web

  include nodejs

  include ::ghost
  create_resources('ghost::blog', hiera_hash('ghost::blogs', {}))
}

Usage

This module has one main class, ghost, with the following parameters:

$user           = 'ghost',                       # Ghost should run as its own user
$group          = 'ghost',                       # Ghost GID and group to create
$home           = '/home/ghost',                 # Ghost user's home directory, default base for blogs
$include_nodejs = false,                         # Whether or not setup should include nodejs module

It delegates the user and group resources to ghost::setup, which creates the user and group you specify (ghost by default) and installs nodejs and NPM using the puppetlabs-nodejs module.

Ghost requires an up-to-date nodejs, which can be done automatically by setting that class's manage_repo parameter to true. If the nodejs class is not defined elsewhere, this module will simply include it.

The module has one main resource, ghost::blog, with the following parameters:

$user   = 'ghost',                          # Ghost instance should run as its own user
$group  = 'ghost',
$home   = "/home/ghost/${title}",           # Root of Ghost instance (will be created if itdoesnot already exist)
$source = 'https://ghost.org/zip/ghost-latest.zip', # Source for ghost distribution
# The npm registry on some distributions needs to be set
$manage_npm_registry = true,                          # Whether or not to attempt to set thenpmregistry (often needed)
$npm_registry        = 'https://registry.npmjs.org/', # User's npm registry
$use_supervisor = true, # User supervisor module to setup service for blog
$autorestart    = true, # Restart on crash
$stdout_logfile = "/var/log/ghost_${title}.log",
$stderr_logfile = "/var/log/ghost_${title}_err.log",
$manage_config = true, # Manage Ghost's config.js
$url    = 'https://my-ghost-blog.com', # Required URL of blog
$socket = true,                        # Set to false to use host and port
$host   = '127.0.0.1',                 # Host to listen on if not using socket
$port   = '2368',                      # Port of host to listen on
$transport    = '', # Mail transport
$fromaddress  = '', # Mail from address
$mail_options = {}, # Hash for mail options

You will likely want to proxy the Ghost instance using, say, nginx. The setup of nginx is outside the scope of this module.

Limitations

  • This module only officially supports Ubuntu, but ought to work with other operating systems as well.

  • If managing the blog's config.js via this module, you cannot currently setup custom databases

  • The socket file created by Ghost must be readable by the web server (perhaps Nginx) for communication to take place, but its default permissions of 660 do not allow this. Because the Ghost server creates the socket file on each launch, it is impossible to control its permissions through Puppet. The best solution to this predicament (see issue #14) is to add your web server's user to Ghost's group (e.g. usermod -a -G ghost www-data), which will allow it to read the socket.

Upgrading from 0.2.x

There are not many changes from 0.2.0 except the following:

  • npm registry management is now done in the ghost::blog type, and is controlled by the npm_registry parameter
  • setting up node using the pupppetlabs-nodejs module is now disabled by default, and can be enabled by the use of the manage_nodejs parameter

Upgrading from 0.1.x

To upgrade to 0.2.x from 0.1.x, you need to be aware of some major changes:

  • The license has changed from MIT to GNU Affero
  • The Ghost source parameter has been moved to ghost::blog
  • Blog's can have different settings for home (root of Ghost)
  • The proletaryo/supervisor module is now used to create a supervisor program in a cross-platform manner
  • The puppetlabs/nodejs module is now used to install nodejs and npm in a cross-platform manner
  • The 'development' config settings have been removed, in favor of setting up only production url, host, and port parameters
  • By default, Ghost is now setup to listen on a Unix socket at the location of the socket parameter (false disables this and falls back to host and port)
  • For most common uses, the socket file must have 'other' read/write permissions, and this is done with an exec because Ghost creates the socket file (Puppet is incapable of this)
  • Mail parameters transport, fromaddress, and a mail_options hash can be specified for each blog
  • The wget module dependency has been deprecated in favor of a simple call to curl
