Setting up Dynamic DNS (optional)

The playbook can configure Dynamic DNS with ddclient⁠ for you. It is a Perl client used to update dynamic DNS entries for accounts on Dynamic DNS Network Service Provider.

Most cloud providers / ISPs will charge you extra for a static IP address. If you're not hosting a highly reliable homeserver you can workaround this via dynamic DNS.

Prerequisite

You'll need to get a username and password from your DNS provider. Please consult with the provider about how to retrieve them.

Adjusting the playbook configuration

To enable dynamic DNS, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

matrix_dynamic_dns_enabled: true

matrix_dynamic_dns_domain_configurations:
  - provider: example.net
    protocol: dyndn2
    username: YOUR_USERNAME_HERE
    password: YOUR_PASSWORD_HERE
    domain: "{{ matrix_domain }}"

Installing

After configuring the playbook, run the installation command: just install-all or just setup-all
