Arseniy Tashoyan updated FLINK-29145:
-------------------------------------
Description:
When running a FlinkDeployment, we can see error messages:
{code:none}
sed: couldn't open temporary file /opt/flink/conf/sedHIUGh6: Read-only file
system
sed: couldn't open temporary file /opt/flink/conf/sedNALzes: Read-only file
system
/docker-entrypoint.sh: line 73: /opt/flink/conf/flink-conf.yaml: Read-only file
system
/docker-entrypoint.sh: line 89: /opt/flink/conf/flink-conf.yaml.tmp: Read-only
file system
{code}
The script _docker-entrypoint.sh_ tries to modify some settings in
{_}flink-conf.yaml{_}, despite this config file is mounted read-only from a
ConfigMap.
Such on-the-fly config modifications make no sense for deployments in
Kubernetes. Instead we specify Flink settings via the _flinkConfiguration_
setting in the FlinkDeployment descriptor.
In addition, _docker-entrypoint.sh_ tries to modify a deprecated setting
{_}query.server.port{_}:
{code:bash}
set_config_option query.server.port 6125
{code}
The setting query.server.port is deprecated in favor of
{_}queryable-state.server.ports{_}:
