Slavi Pantaleev 51312b8250 Split playbook into multiple roles 
As suggested in #63 (Github issue), splitting the
playbook's logic into multiple roles will be beneficial for
maintainability.

This patch realizes this split. Still, some components
affect others, so the roles are not really independent of one
another. For example:
- disabling mxisd (`matrix_mxisd_enabled: false`), causes Synapse
and riot-web to reconfigure themselves with other (public)
Identity servers.

- enabling matrix-corporal (`matrix_corporal_enabled: true`) affects
how reverse-proxying (by `matrix-nginx-proxy`) is done, in order to
put matrix-corporal's gateway server in front of Synapse

We may be able to move away from such dependencies in the future,
at the expense of a more complicated manual configuration, but
it's probably not worth sacrificing the convenience we have now.

As part of this work, the way we do "start components" has been
redone now to use a loop, as suggested in #65 (Github issue).
This should make restarting faster and more reliable.

## 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`).

## (BC Break) mxisd configuration changes
To be more flexible and to support the upcoming [mxisd](https://github.com/kamax-io/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](roles/matrix-mxisd/defaults/main.yml) 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](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/new) 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](docs/configuring-playbook-ssl-certificates.md).
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](https://github.com/kamax-matrix/mxisd/releases/tag/v1.2.2), which supports [multiple base DNs](https://github.com/kamax-matrix/mxisd/blob/v1.2.2/docs/stores/ldap.md#base).
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](https://github.com/kamax-matrix/mxisd/blob/master/docs/stores/ldap.md) 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](https://github.com/matrix-org/matrix-synapse-ldap3) for you.
Additional details are available in [Setting up the LDAP authentication password provider module](docs/configuring-playbook-ldap-auth.md).
# 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](https://dimension.t2bot.io). 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](https://www.postgresql.org/about/news/1894/) 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 [Maintenance / upgrading PostgreSQL](docs/maintenance-upgrading-postgres.md) 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](https://www.whatsapp.com/) by installing the [mautrix-whatsapp](https://github.com/tulir/mautrix-whatsapp) bridge. This playbook functionality is available thanks to [@izissise](https://github.com/izissise).
Additional details are available in [Setting up Mautrix Whatsapp bridging](docs/configuring-playbook-bridge-mautrix-whatsapp.md).
# 2018-10-25
## Support for controlling Matrix federation
The playbook can now help you with [Controlling Matrix federation](docs/configuring-playbook-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](docs/maintenance-checking-services.md).
# 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](https://matrix.org/docs/spec/client_server/r0.4.0.html#server-discovery) using a `/.well-known/matrix/client` file.
Additional details are available in [Configuring service discovery via .well-known](docs/configuring-well-known.md).
## (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](https://telegram.org/) by installing the [mautrix-telegram](https://github.com/tulir/mautrix-telegram) bridge. This playbook functionality is available thanks to [@izissise](https://github.com/izissise).
Additional details are available in [Setting up Mautrix Telegram bridging](docs/configuring-playbook-bridge-mautrix-telegram.md).
## 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](https://github.com/hlandau/acme) (with the [willwill/acme-docker](https://hub.docker.com/r/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](https://certbot.eff.org/) (with the [certbot/certbot](https://hub.docker.com/r/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](docs/installing.md)
- possibly delete `/matrix/ssl-acmetool-delete-later`
# 2018-08-21
## Matrix Corporal support
The playbook can now install and configure [matrix-corporal](https://github.com/devture/matrix-corporal) for you.
Additional details are available in [Setting up Matrix Corporal](docs/configuring-playbook-matrix-corporal.md).
# 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).
```yaml
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](https://github.com/devture/matrix-synapse-shared-secret-auth) for you.
Additional details are available in [Setting up the Shared Secret Auth password provider module](docs/configuring-playbook-shared-secret-auth.md).
# 2018-08-17
## REST auth support via matrix-synapse-rest-auth
The playbook can now install and configure [matrix-synapse-rest-auth](https://github.com/kamax-io/matrix-synapse-rest-auth) for you.
Additional details are available in [Setting up the REST authentication password provider module](docs/configuring-playbook-rest-auth.md).
## 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](https://github.com/kamax-io/mxisd) Identity Server for you by default.
Additional details are available in [Adjusting mxisd Identity Server configuration](docs/configuring-playbook-mxisd.md).
# 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](docs/configuring-playbook-email.md).
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.
