Hi [~scienmanas] , thanks for letting me know. Since I don’t have assign
permissions, I’ll start working on this. If someone with commit rights wants to
assign the ticket later, that would be great. Thanks!
> Unbound Error Thrown if some variables are not set for SASL/SSL configuration
> -----------------------------------------------------------------------------

> Key: KAFKA-19812
> URL: https://issues.apache.org/jira/browse/KAFKA-19812
> Project: Kafka
> Issue Type: Improvement
> Components: docker
> Affects Versions: 4.1.0
> Reporter: Manas Poddar
> Priority: Minor
>
> I was trying to set up a {*}Kafka container with SASL_SSL configuration{*},
> but I {*}missed setting up some environment variables{*}, and {*}Kafka kept
> exiting with an unbound variable error{*}. I checked the
> *{{/etc/kafka/docker/configure}}* file — it has an *{{ensure}} function* to
> check and instruct the user when a particular environment variable is not
> set. I also {*}checked the Docker history and the parent running file{*}, but
> they {*}gave no clue about running the {{.sh}} files with {{set -u}}{*}.
> This issue is {*}just an enhancement to properly log the error details{*}.
