Overview

This module installs and configures Mattermost, to provide secure, private cloud messaging for teams and enterprises. More information is available at: https://about.mattermost.com.

The name for this deployment solution in the context of the Mattermost branding guidelines is Puppet module for Mattermost by Richard Grainger.

Following automated deployment, the following steps are required to make your system production-ready:

Please see https://docs.mattermost.com for the official Mattermost documentation.

Module Changes

From module version 1.7.0, the default value of conf (the default Mattermost configuration file location) has changed to /etc/mattermost.conf. This is to allow configuration changes made using the web GUI to be preserved during Mattermost application upgrades.

Module Description

The Mattermost module does the following:

  • Installs the Mattermost server from a release archive on the web, an alternative download location within your firewall or using a package.
  • Installs and configures a daemon (service) for Mattermost in the format native to your operating system.
  • Configures Mattermost according to settings you provide.

Setup

What mattermost affects

When using a release archive:

  • Downloads and installs Mattermost server (defaults to /opt/mattermost-${version}).
  • Creates a friendly symbolic link to the installation directory (defaults to /opt/mattermost).
  • Creates a configuration file (defaults to /etc/mattermost.json) based on the vendor-provided configuration file and adds user-supplied options.
  • Create an environment variable configuration file (defaults to /etc/sysconfig/mattermost or /etc/default/mattermost depending on platform) and add user-supplied options.
  • Creates and manages a Mattermost daemon (service) using your operating system's native service provider.

When using a package:

  • Installs the package.
  • Add user-supplied options to the configuration files.
  • Manages the service .

Beginning with mattermost

If you have a suitable database installed for Mattermost server to use as a backend, this is the minimum you need to get Mattermost server working by configuring environment variables that will be used by the installed Mattermost service:

Using Puppet only:

class { 'mattermost':
  override_env_options => {
    'MM_SQLSETTINGS_DRIVERNAME' => 'postgres',
    'MM_SQLSETTINGS_DATASOURCE' => "postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10",
  },
}

Using Puppet and Hiera:

include mattermost

mattermost::override_env_options:
  MM_SQLSETTINGS_DRIVERNAME: postgres
  MM_SQLSETTINGS_DATASOURCE: postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10

Alternatively, the minimum configuration can be supplied by configuring Mattermost's json config file:

Using Puppet only:

class { 'mattermost':
  override_options => {
    'SqlSettings' => {
      'DriverName' => 'postgres',
      'DataSource' => "postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10",
    },
  },
}

Using Puppet and Hiera:

include mattermost

mattermost::override_options:
  SqlSettings:
    DriverName: postgres
    DataSource: postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10

Any of these options will install a Mattermost server listening on the default TCP port (currently 8065).

The module's default behaviour is to download and install Mattermost using a .tar.gz archive. The module can instead install Mattermost using a package. Here is an example using the mattermost-server package in the harbottle-main RPM repo for CentOS 7:

yumrepo { 'harbottle-main':
  baseurl  => 'https://copr-be.cloud.fedoraproject.org/results/harbottle/main/epel-7-$basearch/',
  descr    => 'harbottle-main',
  gpgcheck => true,
  gpgkey   => 'https://copr-be.cloud.fedoraproject.org/results/harbottle/main/pubkey.gpg',
}
-> class { 'mattermost':
  install_from_pkg => true,
  version          => latest,
  conf             => '/etc/mattermost/config.json',
  override_options => {
    'SqlSettings'  => {
      'DriverName' => 'postgres',
      'DataSource' => "postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10",
    },
  },
}

Here is an example of Mattermost using PostgreSQL as a database and NGINX as a reverse proxy, all running on the same system (requires puppetlabs/postgresql and puppet/nginx):

class { 'postgresql::globals':
  manage_package_repo => true,
  version             => '9.4',
}
class { 'postgresql::server':
  ipv4acls => ['host all all 127.0.0.1/32 md5'],
}
postgresql::server::db { 'mattermost':
   user     => 'mattermost',
   password => postgresql_password('mattermost', 'mattermost'),
}
postgresql::server::database_grant { 'mattermost':
  privilege => 'ALL',
  db        => 'mattermost',
  role      => 'mattermost',
}
-> class { 'mattermost':
  override_options => {
    'SqlSettings' => {
      'DriverName' => 'postgres',
      'DataSource' => "postgres://mattermost:mattermost@127.0.0.1:5432/mattermost?sslmode=disable&connect_timeout=10",
    },
  },
}
class { 'nginx': }
nginx::resource::upstream { 'mattermost':
  members => [ 'localhost:8065' ],
}
nginx::resource::server { 'mattermost':
  server_name         => [ 'myserver.mydomain' ],
  proxy               => 'http://mattermost',
  location_cfg_append => {
    'proxy_http_version'          => '1.1',
    'proxy_set_header Upgrade'    => '$http_upgrade',
    'proxy_set_header Connection' => '"upgrade"',
  },
}

With the above code, you should be able to access the Mattermost application at http://myserver.mydomain (or whatever resolvable DNS domain you chose) via the NGINX reverse proxy listening on port 80.

Usage

Mattermost config settings can be set using environment variables or a json file.

Configuration options supplied using environment variables takes precedence over options supplied using the json file and they disable modification using the Service Console.

You must decide which method to use.

Use override_options to change Mattermost's default settings by modifying the json file:

class { 'mattermost':
  override_options => {
    'ServiceSettings' => {
      'ListenAddress' => ":80",
    },
    'TeamSettings' => {
      'SiteName' => 'BigCorp Collaboration',
    },
    'SqlSettings' => {
      'DriverName' => 'postgres',
      'DataSource' => "postgres://mattermost:mattermost@127.0.0.1:5432/mattermost?sslmode=disable&connect_timeout=10",
    },
    'FileSettings' => {
      'Directory' => '/var/mattermost',
    },
  }
}

Use override_env_options to change Mattermost's default settings by modifying environment variables:

class { 'mattermost':
  override_env_options => {
    'MM_SERVICESETTINGS_LISTENADDRESS' => ":80",
    'MM_TEAMSETTINGS_SITENAME'         => 'BigCorp Collaboration',
    'MM_SQLSETTINGS_DRIVERNAME'        => 'postgres',
    'MM_SQLSETTINGS_DATASOURCE'        => "postgres://mattermost:mattermost@127.0.0.1:5432/mattermost?sslmode=disable&connect_timeout=10",
    'MM_FILESETTINGS_DIRECTORY'        => '/var/mattermost',
    },
  }
}

Store file data, such as file uploads, in a separate directory (recommended), json file method:

class { 'mattermost':
  override_options => {
    'FileSettings' => {
      'Directory' => '/var/mattermost',
    },
  },
}

Store file data, such as file uploads, in a separate directory (recommended), environment variables method:

class { 'mattermost':
  override_env_options => {
    'MM_FILESETTINGS_DIRECTORY' => '/var/mattermost',
  },
}

Install a specific version:

class { 'mattermost':
  version => '5.21.0',
}

Install Enterprise edition:

class { 'mattermost':
  edition => 'enterprise',
}

Install a release candidate:

class { 'mattermost':
  version => '5.21.0-rc1',
}

Download from an internal server:

class { 'mattermost':
  version  => '5.21.0',
  full_url => 'http://intranet.bigcorp.com/packages/mattermost.tar.gz',
}

Upgrading Mattermost

The module can elegantly upgrade your Mattermost installation. To upgrade, just specify the new version when it has been released, for example:

class { 'mattermost':
  version => '5.21.0',
}

On the next Puppet run, when using a release archive, the new version will be downloaded and installed; the friendly symbolic link will be changed to point at the new installation directory and the service will be refreshed.

When using a package, the new package will be installed and the service will be refreshed.

Note 1: The Mattermost application supports certain upgrade paths only. Please see the upgrade guide

Note 2: Always backup your data before upgrades.

Note 3: For a seamless upgrade you should store your file data outside of the Mattermost installation directory so that your uploaded files are still accessible after each upgrade. For example:

class { 'mattermost':
  override_env_options => {
    'MM_FILESETTINGS_DIRECTORY' => '/var/mattermost',
  },
}

or

class { 'mattermost':
  override_options => {
    'FileSettings' => {
      'Directory' => '/var/mattermost',
    },
  },
}

Security Updates

We highly recommend users subscribe to the Mattermost security updates email list. When notified of a security update, the maintainers of this deployment solution will make an effort to update to the secure version within 10 days.

override_options

Mattermost config settings can be set using environment variables or a json file.

Configuration options supplied using environment variables takes precedence over options supplied using the json file and disable modification using ther Service Console.

You must decide which method to use.

This is a hash containing overrides to the default settings contained in Mattermost's json config file. Defaults to {} (empty hash).

Note 1: If you decide to configure Mattermost using a json file, you should at least specify SqlSettings, e.g.:

class { 'mattermost':
  override_options => {
    'SqlSettings' => {
      'DriverName' => 'postgres',
      'DataSource' => "postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10",
    },
  },
}

Note 2: To purge existing settings from the configuration file, use the purge_conf parameter.

override_options['FileSettings']['Directory']

An element of the override_options hash that specifies the Mattermost data directory. Setting this element will result in the directory being created with the correct permissions if it does not already exist (unless manage_data_dir is false).

Note: override_env_options['MM_FILESETTINGS_DIRECTORY'] takes precedence over this element.

An absolute path must be specified. Example:

class { 'mattermost':
  override_options => {
    'FileSettings' => {
      'Directory' => '/var/mattermost',
    },
  },
}
override_options['LogSettings']['FileLocation']

An element of the override_options hash that specifies the Mattermost log directory. Setting this element will result in the directory being created with the correct permissions if it does not already exist (unless manage_log_dir is false).

Note: override_env_options['MM_LOGSETTINGS_FILELOCATION'] takes precedence over this element.

An absolute path must be specified. Example:

      'FileLocation' => '/var/log/mattermost',
    },
  },
}
override_env_options

Mattermost config settings can be set using environment variables or a json file.

Configuration options supplied using environment variables takes precedence over options supplied using the json file and disable modification using ther Service Console.

You must decide which method to use.

This is a hash containing overrides to Mattermost's environment variables that will be stored in the env_conf environment variable file. Defaults to {} (empty hash).

Note 1: If you decide to configure Mattermost using environment variables, you should at least specify database settings, e.g.:

class { 'mattermost':
  override_env_options => {
    'MM_SQL_SETTINGS_DRIVERNAME' => 'postgres',
    'MM_SQL_SETTINGS_DATASOURCE' => "postgres://db_user:db_pass@db_host:db_port/mattermost?sslmode=disable&connect_timeout=10",

}

Note 2: To purge existing settings from the environment variable file, use the purge_env_conf parameter.

override_env_options['MM_FILESETTINGS_DIRECTORY']

An element of the override_env_options hash that specifies the Mattermost data directory. Setting this element will result in the directory being created with the correct permissions if it does not already exist (unless manage_data_dir is false).

Note: This takes precedence over override_options['FileSettings']['Directory']

An absolute path must be specified. Example:

class { 'mattermost':
  override_env_options => {
    'MM_FILESETTINGS_DIRECTORY' => '/var/mattermost',
  },
}
override_env_options['MM_LOGSETTINGS_FILELOCATION']

An element of the override_env_options hash that specifies the Mattermost log directory. Setting this element will result in the directory being created with the correct permissions if it does not already exist (unless manage_log_dir is false).

Note: This takes precedence over override_options['LogSettings']['FileLocation']

An absolute path must be specified. Example:

class { 'mattermost':
