Agustin Ferrario 25d423e6b6 Fix errors per spantaleev suggestions
The different configurations are now all lower case, for consistent
naming.

`matrix_nginx_proxy_ssl_config` is now called
`matrix_nginx_proxy_ssl_preset`. The different options for "modern",
"intermediate" and "old" are stored in the main.yml file, instead of
being hardcoded in the configuration files. This will improve the
maintainability of the code.

The "custom" preset was removed. Now if one of the variables is set, it
will use it instead of the preset. This will allow to mix and match more
easily, for example using all the intermediate options but only
supporting TLSv1.2. This will also provide better backward
compatibility.

Configure Nginx (optional, advanced)

By default, this playbook installs its own nginx webserver (in a Docker container) which listens on ports 80 and 443. If that's alright, you can skip this.

Using Nginx status

This will serve a statuspage to the hosting machine only. Useful for monitoring software like longview

matrix_nginx_proxy_proxy_matrix_nginx_status_enabled: true

This will serve the status page under the following addresses:

  • http://matrix.DOMAIN/nginx_status (using HTTP)
  • https://matrix.DOMAIN/nginx_status (using HTTPS)

By default, if matrix_nginx_proxy_nginx_status_enabled is enabled, access to the status page would be allowed from the local IP address of the server. If you wish to allow access from other IP addresses, you can provide them as a list:

matrix_nginx_proxy_proxy_matrix_nginx_status_allowed_addresses:
- 8.8.8.8
- 1.1.1.1

Adjusting SSL in your server

You can adjust how the SSL is served by the nginx server by setting the matrix_nginx_proxy_ssl_preset. This is based on the Mozilla Server Side TLS Recommended configurations. It changes the TLS Protocol, the SSL Cipher Suites and the ssl_prefer_server_ciphers variable of nginx. The posible values are:

  • "modern" - For Modern clients that support TLS 1.3, with no need for backwards compatibility
  • "intermediate" - Recommended configuration for a general-purpose server
  • "old" - Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8

The default is set to "intermediate".

Be really carefull when setting it to "modern". This could break the comunication with other matrix servers, limiting your feration posibilities and the Federarion tester won't work.

If you want to override one of the values used by the preset, you can use this three variables:

  • matrix_nginx_proxy_ssl_protocols: for specifying the supported TLS protocols.
  • matrix_nginx_proxy_ssl_prefer_server_ciphers: for specifying if the server or the client choice when negociating the chipher. It can set to "on" or "off".
  • matrix_nginx_proxy_ssl_ciphers: for specifying the SSL Cipher suites used by nginx.

For more information about this variables, check the roles/matrix-nginx-proxy/defaults/main.yml file.

Synapse + OpenID Connect for Single-Sign-On

If you want to use OpenID Connect as an SSO provider (as per the Synapse OpenID docs), you need to use the following configuration (in your vars.yml file) to instruct nginx to forward /_synapse/oidc to Synapse:

matrix_nginx_proxy_proxy_matrix_client_api_forwarded_location_synapse_oidc_api_enabled: true

Disable Nginx access logs

This will disable the access logging for nginx.

matrix_nginx_proxy_access_log_enabled: false
