Synapse-Ubuntu-ZFS

Server configurations for Ubuntu 22.04 running Synapse

This configuration does not include some hardening configurations, as those are maintained here.

Notes:

• snap ufw blocks Docker by default. ArcticFoxes's Matrix server uses .deb ufw instead.
• Use the .deb certbot package so that you can apply systemd hardening.
• A lot of these configuration files use ArcticFoxes's domain. If you are adopting this to your own system, make sure that you replace them.
• The Certbot-OCSP-Fetcher script can be found here
• You need to create a postgres-socket and add the postgres and matrix-synapse user to it.
• You need to create a matrix-synapse-socket and add the matrix-synapse and nginx user to it.
• Systemd overrides for NGINX and SSHD services are based on GrapheneOS's configurations.
• Systemd override for Synapse is based on Arch Linux's matrix-synapse package.
• The repolists of PostgreSQL and Docker have been modified so that they read GPG keys from /usr/share/keyring by default. Make sure that when you follow upstream's documentation on adding their GPG keys, you adjust the location. For PostgreSQL's GPG key, run curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | gpg --dearmor | sudo tee /usr/share/keyrings/postgresql-debian-repo.gpg >/dev/null
