Niklas Semmler created FLINK-25765:
--------------------------------------
Summary: Kubernetes: flink's configmap and flink's actual config
are out of sync
Key: FLINK-25765
URL: https://issues.apache.org/jira/browse/FLINK-25765
Project: Flink
Issue Type: Bug
Components: Deployment / Kubernetes
Affects Versions: 1.15.0
Reporter: Niklas Semmler
For kubernetes setups, Flink's configmap does not reflect the actual config.
Causes
# Config values are overridden by the environment variables in the docker
image (see FLINK-25764)
# Flink reads the config on start-up, but does not subscribe to changes
# Changes to the config map do not lead to restarts of the flink cluster
Effects
# Users cannot expect to understand Flink's config from the configmap
# TaskManager/JobManager started at different times may start with different
configs, if the user edits the configmap
