Configuring Riot-web (optional)

By default, this playbook used to install the Riot-web Matrix client web application.

Riot has since been renamed to Element.

• to learn how to migrate from Riot to Element, see Migrating to Element below

Migrating to Element

Migrating your custom settings

If you have custom matrix_riot_web_ variables in your inventory/host_vars/matrix.DOMAIN/vars.yml file, you'll need to rename them (matrix_riot_web_ -> matrix_client_element_).

Some other playbook variables (but not all) with riot in their name are also renamed. The playbook checks and warns if you are using the old name for some commonly used ones.

Domain migration

We used to set up Riot at the riot.DOMAIN domain. The playbook now sets up Element at element.DOMAIN by default.

There are a few options for handling this:

• (avoiding changes - using the old riot.DOMAIN domain and avoiding DNS changes) -- to keep using riot.DOMAIN instead of element.DOMAIN, override the domain at which the playbook serves Element: matrix_server_fqn_element: "riot.{{ matrix_domain }}"

• (embracing changes - using only element.DOMAIN) - set up the element.DOMAIN DNS record (see Configuring DNS). You can drop the riot.DOMAIN in this case. If so, you may also wish to remove old SSL certificates (rm -rf /matrix/ssl/config/live/riot.DOMAIN) and renewal configuration (rm -f /matrix/ssl/config/renewal/riot.DOMAIN.conf), so that certbot would stop trying to renew them.

• (embracing changes and transitioning smoothly - using both element.DOMAIN and riot.DOMAIN) - to serve Element at the new domain (element.DOMAIN) and to also have riot.DOMAIN redirect there - set up the element.DOMAIN DNS record (see Configuring DNS) and enable Riot to Element redirection (matrix_nginx_proxy_proxy_riot_compat_redirect_enabled: true).

Re-running the playbook

As always, after making the necessary DNS and configuration adjustments, re-run the playbook to apply the changes:
