# Deuxfleurs on NixOS! This repository contains code to run Deuxfleur's infrastructure on NixOS. It sets up the following: - A Wireguard mesh between all nodes - Consul, with TLS - Nomad, with TLS ## How to welcome a new administrator See: https://guide.deuxfleurs.fr/operations/acces/pass/ Basically: - The new administrator generates a GPG key and publishes it on Gitea - All existing administrators pull their key and sign it - An existing administrator reencrypt the keystore with this new key and push it - The new administrator clone the repo and check that they can decrypt the secrets - Finally, the new administrator must choose a password to operate over SSH with `./passwd prod rick` where `rick` is the target username ## How to create files for a new zone *The documentation is written for the production cluster, the same apply for other clusters.* Basically: - Create your `site` file in `cluster/prod/site/` folder - Create your `node` files in `cluster/prod/node/` folder - Add your wireguard configuration to `cluster/prod/cluster.nix` - You will have to edit your NAT config manually - To get your node's wg public key, you must run `./deploy_prod prod `, see the next section for more information - Add your nodes to `cluster/prod/ssh_config`, it will be used by the various SSH scripts. - If you use `ssh` directly, use `ssh -F ./cluster/prod/ssh_config` - Add `User root` for the first time as your user will not be declared yet on the system ## How to deploy a Nix configuration on a fresh node We suppose that the node name is `datura`. Start by doing the deployment one node at a time, you will have plenty of time in your operator's life to break everything through automation. Run: - `./deploy_wg prod datura` - to generate wireguard's keys - `./deploy_nixos prod datura` - to deploy the nix configuration files - need to be redeployed on all nodes as the new wireguard conf is needed everywhere - `./deploy_password prod datura` - to deploy user's passwords - need to be redeployed on all nodes to setup the password on all nodes - `./deploy_pki prod datura` - to deploy Nomad's and Consul's PKI ## How to operate a node Edit your `~/.ssh/config` file: ``` Host dahlia HostName dahlia.machine.deuxfleurs.fr LocalForward 14646 127.0.0.1:4646 LocalForward 8501 127.0.0.1:8501 LocalForward 1389 bottin.service.prod.consul:389 LocalForward 5432 psql-proxy.service.prod.consul:5432 ``` And then run the TLS proxy: ``` ./tlsproxy prod ``` And then open in your browser: - http://localhost:8500 - http://localhost:4646 ## More Please read README.more.md for more detailed information
