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:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
The shortcut commands with just program are also available: just run-tags install-all,start or just run-tags setup-all,start
just run-tags install-all,start is useful for maintaining your setup quickly when its components remain unchanged. If you adjust your vars.yml to remove other components, you’d need to run just run-tags setup-all,start, or these components will still remain installed. For more information about just shortcuts, take a look at this page: Running just commands
