Ansible >= 2.5 is required

Due to recent playbook improvements and the fact that the world keeps turning, we're bumping the version requirement for Ansible (2.4 -> 2.5).

We've also started building our own Docker image of Ansible (devture/ansible), which is useful for people who can't upgrade their local Ansible installation (see Using Ansible via Docker).

TLS support for Coturn

We've added TLS support to the Coturn TURN server installed by the playbook by default. The certificates from the Matrix domain will be used for the Coturn server.

This feature is enabled by default for new installations. To make use of TLS support for your existing Matrix server's Coturn, make sure to rebuild both Coturn and Synapse:

ansible-playbook -i inventory/hosts setup.yml --tags=setup-coturn,setup-synapse,start

People who have an extra firewall (besides the iptables firewall, which Docker manages automatically), will need to open these additional firewall ports: 5349/tcp (TURN over TCP) and 5349/udp (TURN over UDP).

People who build their own custom playbook from our roles should be aware that:

  • the matrix-coturn role and actually starting Coturn (e.g. --tags=start), requires that certificates are already put in place. For this reason, it's usually a good idea to have the matrix-coturn role execute after matrix-nginx-proxy (which retrieves the certificates).

  • there are a few variables that can help you enable TLS support for Coturn. See the matrix-coturn section in group_vars/matrix-servers.

matrix-nginx-proxy support for serving the base domain

If you don't have a dedicated server for your base domain and want to set up Server Delegation via a well-known file, the playbook has got you covered now.

It's now possible for the playbook to obtain an SSL certificate and serve the necessary files for Matrix Server Delegation on your base domain. Take a look at the new Serving the base domain documentation page.

(BC break) matrix-nginx-proxy data variable renamed

matrix_nginx_proxy_data_path was renamed to matrix_nginx_proxy_base_path.

There's a new matrix_nginx_proxy_data_path variable, which has a different use-purpose now (it's a subdirectory of matrix_nginx_proxy_base_path and is meant for storing various data files).

Dimension Integration Manager support

Thanks to NullIsNot0, the playbook can now (optionally) install the Dimension Integration Manager. To learn more, see the Setting up Dimension documentation page.

2019-03-07

Ability to customize mxisd's email templates

Thanks to Sylvia van Os, mxisd's email templates can now be customized easily. To learn more, see the Customizing email templates documentation page.

Discord bridging support

@Lionstiger has done some great work adding Discord bridging support via matrix-appservice-discord. To learn more, see the Setting up Appservice Discord bridging documentation page.

2019-02-19

Renaming variables

The following playbook variables were renamed:

  • from host_specific_hostname_identity to matrix_domain
  • from hostname_identity to matrix_domain
  • from hostname_matrix to matrix_server_fqn_matrix
  • from hostname_riot to matrix_server_fqn_riot
  • from host_specific_matrix_ssl_lets_encrypt_support_email to matrix_ssl_lets_encrypt_support_email

Doing that, we've simplified things, made names less confusing (hopefully) and moved all variable names under the matrix_ prefix.

2019-02-16

Riot v1.0.1 support

You can now use the brand new and redesigned Riot.

The new version no longer has a homepage by default, so we've also removed the custom homepage that we've been installing.

However, we still provide you with hooks to install your own home.html file by specifying the matrix_riot_web_embedded_pages_home_path variable (used to be called matrix_riot_web_homepage_template before).

2019-02-14

Synapse v0.99.1

As we're moving toward Synapse v1.0, things are beginning to stabilize. Upgrading from v0.99.0 to v0.99.1 should be painless.

If you've been overriding the default configuration so that you can terminate TLS at the Synapse side (matrix_synapse_no_tls: false), you'll now have to replace this custom configuration with matrix_synapse_tls_federation_listener_enabled: true. The matrix_synapse_no_tls variable is no more.

2019-02-06

Synapse v0.99 support and preparation for Synapse v1.0

Matrix is undergoing a lot of changes as it matures towards Synapse v1.0. The first step is the Synapse v0.99 transitional release, which this playbook now supports.

If you've been using this playbook successfully until now, you'd be aware that we've been doing Server Delegation using a _matrix._tcp DNS SRV record (as per Configuring DNS).

Due to changes related to certificate file requirements that will affect us at Synapse v1.0, we'll have to stop using a _matrix._tcp DNS SRV record in the future (when Synapse goes to v1.0 - around 5th of March 2019). We still need to keep the SRV record for now, for backward compatibility with older Synapse versions (lower than v0.99).

What you need to do now is make use of this transitional Synapse v0.99 release to prepare your federation settings for the future. You have 2 choices to prepare yourself for compatibility with the future Synapse v1.0:

2019-02-01

TLS v1.3 support

Now that the nginx Docker image has added support for TLS v1.3, we have enabled that protocol by default.

When using:

  • the integrated nginx server: TLS v1.3 support might not kick in immediately, because the nginx version hasn't been bumped and you may have an older build of the nginx Docker image (currently nginx:1.15.8-alpine). Typically, we do not re-pull images that you already have. When the nginx version gets bumped in the future, everyone will get the update. Until then, you could manually force-pull the rebuilt Docker image by running this on the server: docker pull nginx:1.15.8-alpine.

  • your own external nginx server: if your external nginx server is too old, the new configuration we generate for you in /matrix/nginx-proxy/conf.d/ might not work anymore, because it mentions TLSv1.3 and your nginx version might not support that. You can adjust the SSL protocol list by overriding the matrix_nginx_proxy_ssl_protocols variable. Learn more in the documentation page for Using your own webserver, instead of this playbook's nginx proxy

  • another web server: you don't need to do anything to accommodate this change

IRC bridging support

Devon Maloney (@Plailect) has done some great work bringing IRC bridging support via matrix-appservice-irc. To learn more, see the Setting up Appservice IRC documentation page.

2019-01-29

Running container processes as non-root, without capabilities and read-only

To improve security, this playbook no longer starts container processes as the root user. Most containers were dropping privileges anyway, but we were trusting them with root privileges until they would do that. Not anymore -- container processes now start as a non-root user (usually matrix) from the get-go.

For additional security, various capabilities are also dropped (see why it's important) for all containers.

Additionally, most containers now use a read-only filesystem (see why it's important). Containers are given write access only to the directories they need to write to.

A minor breaking change is the matrix_nginx_proxy_proxy_matrix_client_api_client_max_body_size variable having being renamed to matrix_nginx_proxy_proxy_matrix_client_api_client_max_body_size_mb (note the _mb suffix). The new variable expects a number value (e.g. 25M -> 25). If you weren't customizing this variable, this wouldn't affect you.

matrix-mailer is now based on Exim, not Postfix

While we would have preferred to stay with Postfix, we found out that it cannot run as a non-root user. We've had to replace it with Exim (via the devture/exim-relay container image).

The internal matrix-mailer service (running in a container) now listens on port 8025 (used to be 587 before). The playbook will update your Synapse and mxisd email settings to match (matrix-mailer:587 -> matrix-mailer:8025).

Using the devture/exim-relay container image instead of panubo/postfix also gives us a nice disk usage reduction (~200MB -> 8MB).

2019-01-17

(BC Break) Making the playbook's roles more independent of one another

The following change affects people running a more non-standard setup - external Postgres or using our roles in their own other playbook. Most users don't need to do anything, besides becoming aware of the new glue variables file group_vars/matrix-servers.

Because people like using the playbook's components independently (outside of this playbook) and because it's much better for maintainability, we've continued working on separating them. Still, we'd like to offer a turnkey solution for running a fully-featured Matrix server, so this playbook remains important for wiring up the various components.

With the new changes, all roles are now only dependent on the minimal matrix-base role. They are no longer dependent among themselves.

In addition, the following components can now be completely disabled (for those who want/need to):

  • matrix-coturn by using matrix_coturn_enabled: false
  • matrix-mailer by using matrix_mailer_enabled: false
  • matrix-postgres by using matrix_postgres_enabled: false

The following changes had to be done:

  • glue variables had to be introduced to the playbook, so it can wire together the various components. Those glue vars are stored in the group_vars/matrix-servers file. When overriding variables for a given component (role), you need to be aware of both the role defaults (role/ROLE/defaults/main.yml) and the role's corresponding section in the group_vars/matrix-servers file.

  • matrix_postgres_use_external has been superceeded by the more consistently named matrix_postgres_enabled variable and a few other matrix_synapse_database_ variables. See the Using an external PostgreSQL server (optional) documentation page for an up-to-date replacement.

  • Postgres tools (matrix-postgres-cli and matrix-make-user-admin) are no longer installed if you're not enabling the matrix-postgres role (matrix_postgres_enabled: false)

  • roles, being more independent now, are more minimal and do not do so much magic for you. People that are building their own playbook using our roles will definitely need to take a look at the group_vars/matrix-servers file and adapt their playbooks with the same (or similar) wiring logic.

2019-01-16

Splitting the playbook into multiple roles

For better maintainability, the playbook logic (which all used to reside in a single matrix-server role) has been split out into a number of different roles: matrix-synapse, matrix-postgres, matrix-riot-web, matrix-mxisd, etc. (see the roles/ directory).

To keep the filesystem more consistent with this separation, the Postgres data had to be relocated.

The default value of matrix_postgres_data_path was changed from /matrix/postgres to /matrix/postgres/data. The /matrix/postgres directory is what we consider a base path now (new variable matrix_postgres_base_path). Your Postgres data files will automatically be relocated by the playbook (/matrix/postgres/* -> /matrix/postgres/data/) when you run with --tags=setup-all (or --tags=setup-postgres). While this shouldn't cause data-loss, it's better if you do a Postgres backup just in case. You'd need to restart all services after this migration (--tags=start).

2019-01-11

(BC Break) mxisd configuration changes

To be more flexible and to support the upcoming mxisd 1.3.0 (when it gets released), we've had to redo how mxisd gets configured.

The following variables are no longer supported by this playbook:

  • matrix_mxisd_ldap_enabled
  • matrix_mxisd_ldap_connection_host
  • matrix_mxisd_ldap_connection_tls
  • matrix_mxisd_ldap_connection_port
  • matrix_mxisd_ldap_connection_baseDn
  • matrix_mxisd_ldap_connection_baseDns
  • matrix_mxisd_ldap_connection_bindDn
  • matrix_mxisd_ldap_connection_bindDn
  • matrix_mxisd_ldap_connection_bindPassword
  • matrix_mxisd_ldap_filter
  • matrix_mxisd_ldap_attribute_uid_type
  • matrix_mxisd_ldap_attribute_uid_value
  • matrix_mxisd_ldap_connection_bindPassword
  • matrix_mxisd_ldap_attribute_name
  • matrix_mxisd_ldap_attribute_threepid_email
  • matrix_mxisd_ldap_attribute_threepid_msisdn
  • matrix_mxisd_ldap_identity_filter
  • matrix_mxisd_ldap_identity_medium
  • matrix_mxisd_ldap_auth_filter
  • matrix_mxisd_ldap_directory_filter
  • matrix_mxisd_template_config

You are encouraged to use the matrix_mxisd_configuration_extension_yaml variable to define your own mxisd configuration additions and overrides. Refer to the default variables file for more information.

This new way of configuring mxisd is beneficial because:

  • it lets us support all mxisd configuration options, as the playbook simply forwards them to mxisd without needing to care or understand them
  • it lets you upgrade to newer mxisd versions and make use of their features, without us having to add support for them explicitly

2019-01-08

(BC Break) Cronjob schedule no longer configurable

Due to the way we manage cronjobs now, you can no longer configure the schedule they're invoked at.

If you were previously using matrix_ssl_lets_encrypt_renew_cron_time_definition or matrix_nginx_proxy_reload_cron_time_definition to set a custom schedule, you should note that these variables don't affect anything anymore.

If you miss this functionality, please open an Issue and let us know about your use case!

2018-12-23

(BC Break) More SSL certificate retrieval methods

The playbook now lets you decide between 3 different SSL certificate retrieval methods:

  • (default) obtaining free SSL certificates from Let's Encrypt
  • generating self-signed SSL certificates
  • managing SSL certificates manually

Learn more in Adjusting SSL certificate retrieval.

For people who use Let's Encrypt (mostly everyone, since it's the default), you'll also have to rename a variable in your configuration:

  • before: host_specific_matrix_ssl_support_email
  • after: host_specific_matrix_ssl_lets_encrypt_support_email

(BC Break) mxisd upgrade with multiple base DN support

mxisd has bee upgraded to version 1.2.2, which supports multiple base DNs.

If you were configuring this playbook's matrix_mxisd_ldap_connection_baseDn variable until now (a string containing a single base DN), you'll need to change to configuring the matrix_mxisd_ldap_connection_baseDns variable (an array containing multiple base DNs).

Example change:

  • before: matrix_mxisd_ldap_connection_baseDn: OU=Users,DC=example,DC=org
  • after: matrix_mxisd_ldap_connection_baseDns: ['OU=Users,DC=example,DC=org']

2018-12-21

Synapse 0.34.0 and Python 3

Synapse has been upgraded to 0.34.0 and now uses Python 3. Based on feedback from others, running Synapse on Python 3 is supposed to decrease memory usage significantly (~2x).

2018-12-12

Riot homepage customization

You can now customize some parts of the Riot homepage (or even completely replace it with your own custom page). See the matrix_riot_web_homepage_ variables in roles/matrix-riot-web/defaults/main.yml.

2018-12-04

mxisd extensibility

The LDAP identity store for mxisd can now be configured easily using playbook variables (see the matrix_mxisd_ldap_ variables in roles/matrix-server/defaults/main.yml).

2018-11-28

More scripts

  • matrix-remove-all allows to uninstall everything with a single command
  • matrix-make-user-admin allows to upgrade a user's privileges

LDAP auth support via matrix-synapse-ldap3

The playbook can now install and configure LDAP auth support for you.

Additional details are available in Setting up the LDAP authentication password provider module.

2018-11-23

Support for controlling public registration and room auto-join

The playbook now lets you enable public registration for users (controlled via matrix_synapse_enable_registration). By default, public registration is forbidden.

You can also make people automatically get auto-joined to rooms (controlled via matrix_synapse_auto_join_rooms).

Support for changing the welcome user id (welcome bot)

By default, @riot-bot:matrix.org is used to welcome newly registered users. This can be changed to something else (or disabled) via the new matrix_riot_web_welcome_user_id variable.

2018-11-14

Ability to set Synapse log levels

The playbook now allows you to set the log levels used by Synapse. The default logging levels remain the same.

You can now override following variables with any of the supported log levels listed here: https://docs.python.org/3/library/logging.html#logging-levels

matrix_synapse_log_level: "INFO"
matrix_synapse_storage_sql_log_level: "INFO"
matrix_synapse_root_log_level: "INFO"

2018-11-03

Customize parts of Riot's config

You can now customize some parts of Riot's config.json. These playbook variables, with these default values, have been added:

matrix_riot_web_disable_custom_urls: true
matrix_riot_web_disable_guests: true
matrix_riot_web_integrations_ui_url: "https://scalar.vector.im/"
matrix_riot_web_integrations_rest_url: "https://scalar.vector.im/api"
matrix_riot_web_integrations_widgets_urls: "https://scalar.vector.im/api"
matrix_riot_web_integrations_jitsi_widget_url: "https://scalar.vector.im/api/widgets/jitsi.html"

This now allows you use a custom integrations manager like Dimesion. For example, if you wish to use the Dimension instance hosted at dimension.t2bot.io, you can set the following in your vars.yml file:

matrix_riot_web_integrations_ui_url: "https://dimension.t2bot.io/riot"
matrix_riot_web_integrations_rest_url: "https://dimension.t2bot.io/api/v1/scalar"
matrix_riot_web_integrations_widgets_urls: "https://dimension.t2bot.io/widgets"
matrix_riot_web_integrations_jitsi_widget_url: "https://dimension.t2bot.io/widgets/jitsi"

SSL protocols used to serve Riot and Synapse

There's now a new matrix_nginx_proxy_ssl_protocols playbook variable, which controls the SSL protocols used to serve Riot and Synapse. Its default value is TLSv1.1 TLSv1.2. This playbook previously used TLSv1 TLSv1.1 TLSv1.2 to serve Riot and Synapse.

You may wish to reenable TLSv1 if you need to access Riot in older browsers.

Note: Currently the dockerized nginx doesn't support TLSv1.3. See https://github.com/nginxinc/docker-nginx/issues/190 for more details.

2018-11-01

Postgres 11 support

The playbook now installs Postgres 11 by default.

If you have have an existing setup, it's likely running on an older Postgres version (9.x or 10.x). You can easily upgrade by following the upgrading PostgreSQL guide.

(BC Break) Renaming playbook variables

Due to the large amount of features added to this playbook lately, to keep things manageable we've had to reorganize its configuration variables a bit.

The following playbook variables were renamed:

  • from matrix_docker_image_mxisd to matrix_mxisd_docker_image
  • from matrix_docker_image_mautrix_telegram to matrix_mautrix_telegram_docker_image
  • from matrix_docker_image_mautrix_whatsapp to matrix_mautrix_whatsapp_docker_image
  • from matrix_docker_image_mailer to matrix_mailer_docker_image
  • from matrix_docker_image_coturn to matrix_coturn_docker_image
  • from matrix_docker_image_goofys to matrix_s3_goofys_docker_image
  • from matrix_docker_image_riot to matrix_riot_web_docker_image
  • from matrix_docker_image_nginx to matrix_nginx_proxy_docker_image
  • from matrix_docker_image_synapse to matrix_synapse_docker_image
  • from matrix_docker_image_postgres_v9 to matrix_postgres_docker_image_v9
  • from matrix_docker_image_postgres_v10 to matrix_postgres_docker_image_v10
  • from matrix_docker_image_postgres_latest to matrix_postgres_docker_image_latest

2018-10-26

Mautrix Whatsapp bridging support

The playbook now supports bridging with Whatsapp by installing the mautrix-whatsapp bridge. This playbook functionality is available thanks to @izissise.

Additional details are available in Setting up Mautrix Whatsapp bridging.

2018-10-25

Support for controlling Matrix federation

The playbook can now help you with Controlling Matrix federation, should you wish to run a more private (isolated) server.

2018-10-24

Disabling riot-web guests

From now on, Riot's configuration setting disable_guests would be set to true. The homeserver was rejecting guests anyway, so this is just a cosmetic change affecting Riot's UI.

2018-10-21

Self-check maintenance command

The playbook can now check if services are configured correctly.

2018-10-05

Presence tracking made configurable

The playbook can now enable/disable user presence-status tracking in Synapse, through the playbook's matrix_synapse_use_presence variable (having a default value of true - enabled).

If users participate in large rooms with many other servers, disabling presence will decrease server load significantly.

2018-09-27

Synapse Cache Factor made configurable

The playbook now makes the Synapse cache factor configurable, through the playbook's matrix_synapse_cache_factor variable (having a default value of 0.5).

Changing that value allows you to potentially decrease RAM usage or to increase performance by caching more stuff. Some information on it is available here: https://github.com/matrix-org/synapse#help-synapse-eats-all-my-ram

2018-09-26

Disabling Docker container logging

--log-driver=none is used for all Docker containers now.

All these containers are started through systemd anyway and get logged in journald, so there's no need for Docker to be logging the same thing using the default json-file driver. Doing that was growing /var/lib/docker/containers/.. infinitely until service/container restart.

As a result of this, things like docker logs matrix-synapse won't work anymore. journalctl -u matrix-synapse is how one can see the logs.

2018-09-17

Service discovery support

The playbook now helps you set up service discovery using a /.well-known/matrix/client file.

Additional details are available in Configuring service discovery via .well-known.

(BC Break) Renaming playbook variables

The following playbook variables were renamed:

  • from matrix_nginx_riot_web_data_path to matrix_riot_web_data_path
  • from matrix_riot_web_default_identity_server_url to matrix_identity_server_url

2018-09-07

Mautrix Telegram bridging support

The playbook now supports bridging with Telegram by installing the mautrix-telegram bridge. This playbook functionality is available thanks to @izissise.

Additional details are available in Setting up Mautrix Telegram bridging.

Events cache size increase and configurability for Matrix Synapse

The playbook now lets you configure Matrix Synapse's event_cache_size configuration via the matrix_synapse_event_cache_size playbook variable.

Previously, this value was hardcoded to "10K". From now on, a more reasonable default of "100K" is used.

Password-peppering support for Matrix Synapse

The playbook now supports enabling password-peppering for increased security in Matrix Synapse via the matrix_synapse_password_config_pepper playbook variable. Using a password pepper is disabled by default (just like it used to be before this playbook variable got introduced) and is not to be enabled/disabled after initial setup, as that would invalidate all existing passwords.

Statistics-reporting support for Matrix Synapse

There's now a new matrix_synapse_report_stats playbook variable, which controls the report_stats configuration option for Matrix Synapse. It defaults to false, so no change is required to retain your privacy.

If you'd like to start reporting statistics about your homeserver (things like number of users, number of messages sent, uptime, load, etc.) to matrix.org, you can turn on stats reporting.

2018-08-29

Changing the way SSL certificates are retrieved

We've been using acmetool (with the willwill/acme-docker Docker image) until now.

Due to the Docker image being deprecated, and things looking bleak for acmetool's support of the newer ACME v2 API endpoint, we've switched to using certbot (with the certbot/certbot Docker image).

Simply re-running the playbook will retrieve new certificates (via certbot) for you. To ensure you don't leave any old files behind, though, you'd better do this:

  • systemctl stop 'matrix*'
  • stop your custom webserver, if you're running one (only affects you if you've installed with matrix_nginx_proxy_enabled: false)
  • mv /matrix/ssl /matrix/ssl-acmetool-delete-later
  • re-run the playbook's installation
  • possibly delete /matrix/ssl-acmetool-delete-later

2018-08-21

Matrix Corporal support

The playbook can now install and configure matrix-corporal for you.

Additional details are available in Setting up Matrix Corporal.

2018-08-20

Matrix Synapse rate limit control variables

The following new variables can now be configured to control Matrix Synapse's rate-limiting (default values are shown below).

matrix_synapse_rc_messages_per_second: 0.2
matrix_synapse_rc_message_burst_count: 10.0

Shared Secret Auth support via matrix-synapse-shared-secret-auth

The playbook can now install and configure matrix-synapse-shared-secret-auth for you.

Additional details are available in Setting up the Shared Secret Auth password provider module.

2018-08-17

REST auth support via matrix-synapse-rest-auth

The playbook can now install and configure matrix-synapse-rest-auth for you.

Additional details are available in Setting up the REST authentication password provider module.

Compression improvements

Shifted Matrix Synapse compression from happening in the Matrix Synapse, to happening in the nginx proxy that's in front of it.

Additionally, riot-web also gets compressed now (in the nginx proxy), which drops the initial page load's size from 5.31MB to 1.86MB.

Disabling some unnecessary Synapse services

The following services are not necessary, so they have been disabled:

  • on the federation port (8448): the client service
  • on the http port (8008, exposed over 443): the old Angular webclient and the federation service

Federation runs only on the federation port (8448) now. The Client APIs run only on the http port (8008) now.

2018-08-15

mxisd Identity Server support

The playbook now sets up an mxisd Identity Server for you by default. Additional details are available in Adjusting mxisd Identity Server configuration.

2018-08-14

Email-sending support

The playbook now configures an email-sending service (postfix) by default. Additional details are available in Adjusting email-sending settings.

With this, Matrix Synapse is able to send email notifications for missed messages, etc.

2018-08-08

(BC Break) Renaming playbook variables

The following playbook variables were renamed:

  • from matrix_max_upload_size_mb to matrix_synapse_max_upload_size_mb
  • from matrix_max_log_file_size_mb to matrix_synapse_max_log_file_size_mb
  • from matrix_max_log_files_count to matrix_synapse_max_log_files_count
  • from docker_matrix_image to matrix_docker_image_synapse
  • from docker_nginx_image to matrix_docker_image_nginx
  • from docker_riot_image to matrix_docker_image_riot
  • from docker_goofys_image to matrix_docker_image_goofys
  • from docker_coturn_image to matrix_docker_image_coturn

If you're overriding any of them in your vars.yml file, you'd need to change to the new names.

Renaming Ansible playbook tag

The command for executing the whole playbook has changed. The setup-main tag got renamed to setup-all.

Docker container linking

Changed the way the Docker containers are linked together. The ones that need to communicate with others operate in a matrix network now and not in the default bridge network.

You can’t perform that action at this time.
