 Da Secrets aber durchaus doch gebraucht werden, werden diese dann in diesem Repo direkt aus dem [password-store](https://gitlab.hamburg.ccc.de/ccchh/password-store) (meist aus einem Sub-Eintrag des `noc/` Ordners) geladen.
 Dies geschieht mit Hilfe des `community.general.passwordstore` lookup Plugins.

+
+## Playbook nur für einzelne Hosts ausführen
+
+Ein paar der Hosts haben den selben Namen, was es etwas schwieriger macht, das Playbook nur für einen der Hosts auszuführen, z. B. `public-reverse-proxy`. Die Kombination aus `--inventory` und `--limit` führt zum Erfolg:
+```
+ansible-playbook playbooks/deploy.yaml --inventory inventories/chaosknoten/hosts.yaml --limit public-reverse-proxy
+```
+
+## Neuen Web-Service hinzufügen
+
+Wir deployen Web-Services hinter dem `public-reverse-proxy`. Der Service-Name `service.hamburg.ccc.de` ist ein CNAME für public-reverse-proxy.hamburg.ccc.de, und die Service-VM ist unter `service-intern.hamburg.ccc.de` mit einer `172.31.17.x`-Adresse erreichbar.
+
+Im Ansible-Repo müssen diese Sachen hinzugefügt werden:
+* `inventories/chaosknoten/hosts.yaml`: 
+    * SSH-Config für die neue VM unter all/children/debian_12/hosts
+    * Einträge für die Rollen, die dieser Host haben soll, min. `certbot_hosts`, `nginx_hosts`, ggf. `docker_compose_hosts`
+* `inventories/chaosknoten/host_vars/`*host*`.yaml`: config vars für den neuen Host
+* `playbooks/files/chaosknoten/configs/public-reverse-proxy/nginx/acme_challenge.conf`: Liste der Hostnamen um den neuen Host erweitern, die hinter dem Reverse-Proxy stehen
+* `playbooks/files/chaosknoten/configs/public-reverse-proxy/nginx/nginx.conf`: Liste der Hostnamen um den neuen Host erweitern, die hinter dem Reverse-Proxy stehen
+* `playbooks/files/chaosknoten/configs/cloud/nginx/`*host*`.hamburg.ccc.de.conf`: Server auf dem Service-Host
+    * Individuelle Config für den Service. Wenn Docker Compose, hier weiterleiten auf den eigentlichen Dienst in Compose.
+    * Cert-Dateinamen anpassen
+* `playbooks/templates/chaosknoten/configs/`*host*`/compose.yaml.j2`: Config für Docker Compose (wenn verwendet)
