kafka readiness probes failing
You're binding your kafka to zookeeper in a way that it's not a good practice.
I use kafka from apache official site and I have found that there's a specific script to make a readiness probe:
readinessProbe: exec: command: - sh - -c - "/opt/kafka/bin/kafka-broker-api-versions.sh --bootstrap-server=localhost:9092"
I had similar issue. following changes, helped me overcoming this.
# readinessProbe & livenessProbe readinessProbe: tcpSocket: port: 9092 timeoutSeconds: 5 periodSeconds: 5 initialDelaySeconds: 45 livenessProbe: exec: command: - sh - -c - "kafka-broker-api-versions.sh --bootstrap-server=localhost:9092" timeoutSeconds: 5 periodSeconds: 5 initialDelaySeconds: 60Basing on your requirement, You can update following value.
initialDelaySeconds
