# Deuxfleurs on NixOS!
|
|
|
|
This repository contains code to run Deuxfleur's infrastructure on NixOS.
|
|
|
|
## Our abstraction stack
|
|
|
|
We try to build a generic abstraction stack between our different resources (CPU, RAM, disk, etc.) and our services (Chat, Storage, etc.), we develop our own tools when needed.
|
|
|
|
Our first abstraction level is the NixOS level, which installs a bunch of standard components:
|
|
|
|
* **Wireguard:** provides encrypted communication between remote nodes
|
|
* **Nomad:** schedule containers and handle their lifecycle
|
|
* **Consul:** distributed key value store + lock + service discovery
|
|
* **Docker:** package, distribute and isolate applications
|
|
|
|
Then, inside our Nomad+Consul orchestrator, we deploy a number of base services:
|
|
|
|
* **[Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/):** S3-compatible lightweight object store for self-hosted geo-distributed deployments (we also have a legacy glusterfs cluster)
|
|
* **[DiploNAT](https://git.deuxfleurs.fr/Deuxfleurs/diplonat):** network automation (firewalling, upnp igd)
|
|
* **[Bottin](https://git.deuxfleurs.fr/Deuxfleurs/bottin):** authentication and authorization (LDAP protocol, consul backend)
|
|
* **[Guichet](https://git.deuxfleurs.fr/Deuxfleurs/guichet):** a dashboard for our users and administrators
|
|
* **Stolon + PostgreSQL:** distributed relational database
|
|
* **Prometheus + Grafana:** monitoring
|
|
|
|
Some services we provide based on this abstraction:
|
|
|
|
* **Websites:** Garage (static) + fediverse blog (Plume)
|
|
* **Chat:** Synapse + Element Web (Matrix protocol)
|
|
* **Email:** Postfix SMTP + Dovecot IMAP + opendkim DKIM + Sogo webmail | Alps webmail (experimental)
|
|
* **Visioconference:** Jitsi
|
|
* **Collaboration:** CryptPad
|
|
|
|
As a generic abstraction is provided, deploying new services should be easy.
