Subject: Phase 3: KRAFT-Konfig bei Brokern ergänzt
X-Git-Url: http://juplo.de/gitweb/?a=commitdiff_plain;h=ea6ef79033f197c6eb196b26361d3da38c9d2a8e;p=demos%2Fkafka%2Ftraining

Phase 3: KRAFT-Konfig bei Brokern ergänzt

* Rolling Upgrade der Broker notwendig:
+
[source]
--
docker compose up -d kafka-1 ; docker compose logs --tail=10 -f kafka-1
docker compose up -d kafka-2 ; docker compose logs --tail=10 -f kafka-2
docker compose up -d kafka-3 ; docker compose logs --tail=10 -f kafka-3
--
* Das Setup ist so noch nicht Lauf- bzw. Migrationsfähig!
* Grund: Die Inter-Broker-Kommunikation zwischen Brokern und Controllern fehlt
** Fehler auf Broker-Seite:
+
[source]
--
Unable to register broker 1 because the controller returned error INVALID_REGISTRATION
--
** Fehler auf Controller-Seite:
+
[source]
--
Exception message: Broker does not have the current inter.broker.listener PLAINTEXT
