> Key: FLINK-22648
> URL: https://issues.apache.org/jira/browse/FLINK-22648
> Project: Flink
> Issue Type: Improvement
> Components: flink-docker
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: docker-1.13.0.1
>
>
> The docker entrypoint always runs this code:
> {code:java}
> TASK_MANAGER_NUMBER_OF_TASK_SLOTS=${TASK_MANAGER_NUMBER_OF_TASK_SLOTS:-1}
> set_config_option taskmanager.numberOfTaskSlots
> ${TASK_MANAGER_NUMBER_OF_TASK_SLOTS} {code}
> This always overrides the number of task slots, either with the value that
> was set by the user or otherwise, 1.
> This means that users cannot mount a different config to change the number of
> slots.
> We should only configure the number of slots if the environment variable was
> actually set.
