 **OBSOLETION NOTICE:** We are progressively migrating our stack to NixOS, to replace Ansible. Most of the files present in this repository are outdated or obsolete,
 the current code for our infrastructure is at: <https://git.deuxfleurs.fr/Deuxfleurs/nixcfg>.
 
-## 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:
-
-  * **[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
-  * **ansible:** physical node configuration
-  * **nomad:** schedule containers and handle their lifecycle
-  * **consul:** distributed key value store + lock + service discovery
-  * **stolon + postgresql:** distributed relational database
-  * **docker:** package, distribute and isolate applications
-
-Some services we provide:
-
-  * **Websites:** garage (static) + fediverse blog (plume)
-  * **Chat:** Synapse + Element Web (Matrix protocol)
-  * **Email:** Postfix SMTP + Dovecot IMAP + opendkim DKIM + Sogo webmail (legacy) | Alps webmail (experimental)
-  * **Storage:** Seafile (legacy) | Nextcloud (experimental)
-  * **Visio:** Jitsi
-
-As a generic abstraction is provided, deploying new services should be easy.

-## Start hacking
-
-### Deploying/Updating new services is done from your machine
-
-*The following instructions are provided for ops that already have access to the servers (meaning: their SSH public key is known by the cluster).*
-
-Deploy Nomad on your machine:
-
-```bash
-export NOMAD_VER=1.0.1
-wget https://releases.hashicorp.com/nomad/${NOMAD_VER}/nomad_${NOMAD_VER}_linux_amd64.zip
-unzip nomad_${NOMAD_VER}_linux_amd64.zip
-sudo mv nomad /usr/local/bin
-rm nomad_${NOMAD_VER}_linux_amd64.zip
-```
-
-Deploy Consul on your machine:
-
-```bash
-export CONSUL_VER=1.9.0
-wget https://releases.hashicorp.com/consul/${CONSUL_VER}/consul_${CONSUL_VER}_linux_amd64.zip
-unzip consul_${CONSUL_VER}_linux_amd64.zip
-sudo mv consul /usr/local/bin
-rm consul_${CONSUL_VER}_linux_amd64.zip
-```
-
-Create an alias (and put it in your `.bashrc`) to bind APIs on your machine:
-
-```
-alias bind_df="ssh \
-  -p110 \
-  -N \
-  -L 1389:bottin2.service.2.cluster.deuxfleurs.fr:389 \
-  -L 4646:127.0.0.1:4646 \
-  -L 5432:psql-proxy.service.2.cluster.deuxfleurs.fr:5432 \
-  -L 8082:traefik-admin.service.2.cluster.deuxfleurs.fr:8082 \
-  -L 8500:127.0.0.1:8500 \
-  <a server from the cluster>"
-```
-
-and run: 
-
-    bind_df
-
-Adrien uses `.ssh/config` configuration instead. I works basically the same. Here it goes:
-
-```
-# in ~/.ssh/config 
-
-Host deuxfleurs
-    User adrien
-    Hostname deuxfleurs.fr
-    # If you don't use the default ~/.ssh/id_rsa to connect to Deuxfleurs
-    IdentityFile <some_key_path>
-    PubKeyAuthentication yes
-    ForwardAgent No
-    LocalForward 1389 bottin2.service.2.cluster.deuxfleurs.fr:389
-    LocalForward 4646 127.0.0.1:4646
-    LocalForward 5432 psql-proxy.service.2.cluster.deuxfleurs.fr:5432
-    LocalForward 8082 traefik-admin.service.2.cluster.deuxfleurs.fr:8082
-    LocalForward 8500 127.0.0.1:8500
-```
-
-Now, to connect, do the following:
-
-    ssh deuxfleurs -N

-## Test cluster

-Configured machines available for testing are listed in the **[`test_cluster` Ansible inventory](./os/config/test_cluster.inventory.yml)**.
