Subject: Setup auf KRAFT mit start über den Service `setup` umgestellt
X-Git-Tag: simple-producer---lvm-2-tage--easy-path~4
X-Git-Url: https://juplo.de/gitweb/?a=commitdiff_plain;h=96a8aea01a81e47f163170779dc7168b2d51a9f1;p=demos%2Fkafka%2Ftraining

Setup auf KRAFT mit start über den Service `setup` umgestellt

* Das Compose-Setup auf KRAFT mit bitnami-Images umgestellt.
* Der Zookeeper wird dann durch eine Controller-Instanz ersetzt
* Durch die definierten Abhängigkeiten kann die gesamte Infrastruktur
  bequme mit `docker-compose up setup` im Hintergrund hochgefahren werden.
  Der Service läuft zwar im Vordergrund, aber die benötigten Services
  werden automatisch im Hintergrund gestartet und der Setup-Service
  beendet sich ja ohnehin nach dem Erzeugen der Topics.
