Mattermost

A role that installs and can configure Mattermost.

This role creates a secure installation of Mattermost, by installing it in /opt/mattermost and disallowing the user running mattermost to edit files in that directory. Uploaded files are saved to /srv/mattermost and the configuration file is not writable by default.

Requirements

An ansible 2.0+ installation and the pieterlexis.json_file module.

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

mattermost_version: 4.3.1

The version of Mattermost to install. The tarball's checksum is retrieved from the _mattermost_versions variable, but can be overwritten by setting mattermost_tar_checksum.

This role installs Mattermost to /opt/mattermost/{{ mattermost_version }} and sym-links /opt/mattermost/current to this directory. This allows for upgrades and downgrades.

mattermost_listen_address: '127.0.0.1:8065'

The address and port Mattermost listens on.

mattermost_database_driver: postgres
mattermost_database_host: localhost
mattermost_database_name: mattermost
mattermost_database_user: mattermost
mattermost_database_password:

The driver, host, database, username and password to connect to the database. Only the "postgresql" driver is supported by this role at the moment.

mattermost_database_create: true

Create the database and database user. Works only if the database is on localhost at the moment.

mattermost_user_create: true
mattermost_user: mattermost
mattermost_group_create: true
mattermost_group: mattermost

The system user and group to run mattermost under. The *_create variables dictate is the user and/or group should be created by this role.

mattermost_config_writable: false

Whether or not the mattermost configuration file should we writable by the mattermost_user. Setting this to true means that system administrators can use the system-console to change settings. On the default, only admins with access to the system (the ones running Ansible) can change settings.

mattermost_config: []

A list of dicts with configuration items and their values, see the json_file documentation and the Example Playbook below for more information.
