> docker entrypoint script cannot handle FLINK_PROPERTIES that include spaces
> ---------------------------------------------------------------------------
>
> Key: FLINK-38587
> URL: https://issues.apache.org/jira/browse/FLINK-38587
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.20.3
> Reporter: Jacob Jona Fahlenkamp
> Priority: Minor
> Attachments: docker-compose.yml
>
>
> Steps to reproduce:
> 1. Download the file [^docker-compose.yml]
> 2. Run with
> {code:java}
> docker compose up{code}
> 3. In the output you can see the whitespaces have been stripped from the
> options.
> {code:java}
> jobmanager-1 | WARNING: Unknown module: ALL-UNNAMED--enable-preview
> specified to --add-opens {code}
> Cause:
> The following entrypoint script removes all spaces in each line. Probably the
> intention was just to strip the spaces from the start and beginning of the
> line. It happens in this line:
> [https://github.com/apache/flink-docker/blob/master/1.20/scala_2.12-java17-ubuntu/docker-entrypoint.sh#L111C11-L111C47]
> Potential solution:
> Replace the line
> {code:java}
> prop=$(echo $prop | tr -d '[:space:]') {code}
> with the following:
> {code:java}
> prop=$(echo "$prop" | sed 's/^[[:space:]]*//;s/[[:space:]]*$//'){code}
