+## k8s minicluster
+
+For k8s installation we use our [dda-k8s-crate](https://github.com/DomainDrivenArchitecture/dda-k8s-crate) with the following configuation:
+
+
+```
+{:user :k8s
+ :k8s {:external-ip "ip-from-above"}
+ :cert-manager :letsencrypt-prod-issuer
+ :persistent-dirs ["cloud", "postgres"]
+ }
+```
+
+## kubectl apply c4k-nextcloud
+
+The last step for applying the nextcloud deployment is
+
+```
+c4k-nextcloud config.edn auth.edn | kubectl apply -f -
+```
+
+with the following config.edn:
+
+```
+{:fqdn "the-fqdn-from aws_route53_record.v4_neu"
+ :cloud-data-volume-path "/var/cloud"                 ;; Volume was configured at dda-k8s-crate, results in a PersistentVolume definition.
+ :postgres-data-volume-path "/var/postgres"         ;; Volume was configured at dda-k8s-crate, results in a PersistentVolume definition.
