Fluxer Server

Fluxer is a free and open source instant messaging and VoIP chat platform
for friends, groups and communities. This snap runs a complete, self-hosted
Fluxer instance (https://fluxer.com/selfhost) natively: the Fluxer API,
gateway, media proxy and web app, plus PostgreSQL, Valkey, NATS,
Meilisearch, SeaweedFS (S3 storage), LiveKit (voice) and Caddy (TLS).
No Docker is needed.

Setup:

sudo snap set fluxer-server domain=chat.example.com

Setting the domain enables and starts every service. Then run sudo fluxer-server.setup-token and open https://chat.example.com to
create the admin account.

The domain needs an A record pointing at this machine. Open TCP 80, 443,
7881 and UDP 443, 7882 in any firewall. To run behind your own reverse
proxy instead, also set behind-proxy=127.0.0.1:8080 and point the proxy
at that address.

Other settings: http-port, https-port, tls (a Caddy tls directive such as
"internal"), livekit-node-ip, and env.<NAME>=<value> for any Fluxer
environment variable, for example snap set fluxer-server env.FLUXEREMAILENABLED=true.
