-# ansible-ffmwu.git
+# Ansible Freifunk MWU
 
-An dieser Stelle soll der ganze ansible-script-junk entstehen, um ein FFMWU-Gateway automagisiert aufzusetzen. Das Geraffel kann später auch auf andere server-Typen erweitert werden, wenn sinnvoll.
+Wir, die Freifunk MWU Community, nutzen Ansible um unsere Freifunk Server aufzusetzen und zu konfigurieren. In
-Ein server muss minimal vorbereitet sein, bevor er mit den hiesigen Skripten zum Gate (oder zu Sonstigem) gemacht werden kann. Insbesondere müssen die folgenden Voraussetzungen erfüllt sein (diese werden vom playbook `test-prerequisites.yml` getestet):
+diesem Repository verwalten wir unsere Ansible Roles und Playbooks.
+
+Ein Server muss minimal vorbereitet sein, bevor dieser per Ansible z.B. zu einem Freifunk-Gateway gemacht werden 
+kann. Die folgenden Voraussetzungen müssen erfüllt sein:
 
 - Ein dedizierter (v)server muss existieren und unter einer IPv4- und einer IPv6-Adresse öffentlich erreichbar sein.
-- Die Adressen sollen im MWU-DNS eingetragen sein.
+- Die Adressen müssen im MWU-DNS eingetragen sein.
-- Es muss eine nakte unterstützte linux-Version aufgesetzt sein (aktuell Ubuntu 14.04, bald Debian).
+- Als Betriebssystem muss Debian Stretch installiert sein.
-- Es muss einen user admin geben, auf den die Admins Zugriff haben; dieser muss root-Zugang über sudo haben.
+- Für Ansible muss Python 2.6 oder höher installiert sein.
+- Es muss einen User admin geben, auf den die Admins Zugriff haben; dieser muss Root-Zugang über sudo haben.
 
-Zusätzlich ist sehr empfehlenswert, dass die Admins die Maschinen mit ihren fqdns in ihrer ssh-config definiert haben.
+Diese Voraussetzungen werden von der Rolle `prerequisites` geprüft, die Rolle sollte als erste Rolle in jedem
+Playbook eingebunden sein.
 
-Bisher gibt es hier zwei Sammlungen von files: zum Einen der Beginn des eigentlichen Zwecks: bisher kann eine Rolle (auf Basis der obigen Voraussetzungen) alle FFMWU-Server in dem ihnen allen identischen Aspekt vorbereiten, der Pflege der ssh keys der admins. Zum Anderen gibt es ein playbook, das eine lokale Test-VM aufsetzt, auf der man alle eigentlichen playbooks und Rollen testen kann, ohne ernsthaften Schaden anzurichten.
+Voraussetzungen für die Control Machine:
 
-## Aufsetzen und Pflegen von Gateways
+- Python 2 (Versionen 2.6 oder 2.7) oder 3 (Versionen 3.5 oder höher)
+- Ansible Version >= 2.4.0.0
+- Python Modul `netaddr`
+- Python Modul `dnspython`
 
-Alle FFMWU-Gatways sind auch FFMWU-Server, alle anderen server bei uns überraschenderweise auch; so sind auch Alle im inventory in der Gruppe 'ff-servers' zusammengefasst. Der Aspekt, der allen FFMWU-Servern gemein ist, sind die ssh-keys der admins. Auf einigen servern gibt es allerdings weitere Zugriffsberechtigte (spezialisierte admins).
+Die Server werden mit ihren FQDNs im Ansible Inventory hinterlegt, bedenkt das für eure ssh-config.
 
-So gibt es eine Rolle ('ffmwu-server'), die allen hosts dieser Gruppe zugewiesen ist (über das playbook 'ffmwu-servers.yml', später auch über Abhängigkeiten der speziellern playbooks). Dieses playbook (einfach starten) weist die Rolle zu, welche ihrerseits die shh keys auf den hosts pflegt.
+## Gruppen-Variablen
+Viele Variablen sind Mesh-spezifisch und werden auf allen Gateways benötigt. Deshalb verwalten wir die Liste `meshes`. Jeder Listeneintrag ist ein Dictionary. Diese Liste befindet sich in der Sondergruppe `all` (inventory/group_vars/all) und steht damit allen Hosts im Inventory zur Verfügung.
+Diese Liste ist quasi das Herzstück zur Konfiguration der Mesh-spezifischen Parameter auf den Freifunk-Gateways. Jedes Dictionary repräsentiert eine Mesh-Wolke/Domain/Layer2-Netzwerk und ist wie folgt aufgebaut (Beispiel Mainz):
 
-Die Rolle besteht aus nur einem task und einer definierten Variable, die die keys der admins enthält. Sind auf einem host weitere ssh keys von Nöten, so werden disse als hostvar definiert.

-Damit auf der lokalen Maschine (der ansible controle machine) VMs ablaufen (und mit dem playbook angelegt werden) können, müssen verschiedene Voraussetzungen erfüllt sein. U. a.:
 
-- installierte Pakete zu libvirt, kvm und qemu und Pakete virt-manager, isomaster
+## Host-Variablen
-- >15G freier Plattenplatz
+Alle Server- bzw. Gateway-spezifischen Parameter werden als Host-Variablen abgebildet:
