Tips for deploying Matrix on a Budget

Dynamic DNS

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. To set this up, you'll need to get the username/password from your DNS provider. For google domains, this process is described here. After you've gotten the proper credentials you can add the following config to your inventory/host_vars/matrix.DOMAIN/vars.yml:

matrix_dynamic_dns_username: XXXXXXXXXXXXXXXX
matrix_dynamic_dns_password: XXXXXXXXXXXXXXXX
matrix_dynamic_dns_provider: 'domains.google.com'
