>             Project: Flink
>          Issue Type: Bug

> 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 file 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_:
