+  * see: [Icinga: Master Setup](https://icinga.com/docs/icinga-2/latest/doc/06-distributed-monitoring/#master-setup)
+
+ATTENTION: primary designed for:
+* [AO-IT: icinga-stack](https://git.ao-it.net/docker/icinga-stack)
+* [AO-IT: icinga2](https://git.ao-it.net/docker/icinga2)
+* [AO-IT: icingaweb2](https://git.ao-it.net/docker/icinga-satellite)
+
+Maybe you need more setup setps if you use other base!
