What steps will reproduce the bug?

1. helm install zookeeper bitnami/zookeeper

Are you using any custom parameters or values?

no, I don't

What is the expected behavior?

What do you see instead?

there is no log files under /opt/bitnami/kafka/logs directory [kafka pod]

I have no name!@kafka-0:/opt/bitnami/kafka/logs$ ls -altr

drwxrwxr-x 1 root root 4096 Jun 11 05:29 ..
drwxrwsrwx 2 root 1001 4096 Jul  4 02:00 .

but I can see kafka log under worker node in kubernete cluster.

Hi,

We configured the kafka chart to redirect all logs to standard output and standard error. Do you see any logs when executing kubectl logs ?

[sumpf]

hello javsalgar, sorry for late reply. yes I can see log with kubectl logs. I wonder if there is option to write kafka log in container or container volume such as PV with values.yaml in helm chart.

Hi guys,

I am hitting the same problem. My tried to set ZOO_LOG4J_PROP = 'INFO, ROLLINGFILE' and ZOO_LOG_LEVEL='INFO' under containers.zookeeper.env. However, no logs are found in the /opt/bitnami/zookeeper/log directory.

Have anyone met and resolved this before.

Thanks :)

it seems container default output is standard output. so it doesn't log in container side but kubernetes node side. https://kubernetes.io/docs/concepts/cluster-administration/logging/

newer version of Kafka charts has slightly modified log4j.properties now
