-------------------------------

             Summary: FLINK_CONF_DIR environment variable to locate flink-conf.yaml in Docker container
                 Key: FLINK-17077
                 URL: https://issues.apache.org/jira/browse/FLINK-17077
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / Docker
            Reporter: Eui Heo


To use flink-conf.yaml outside Flink home directory, we should use FLINK_CONF_DIR.
But despite of FLINK_CONF_DIR is provided, docker-entrypoint.sh in official flink-docker doesn't know FLINK_CONF_DIR and it is ignored when append additional flink properties to flink-conf.yaml. It would be good to use FLINK_CONF_DIR for the location of flink-conf.yaml, if user provide it.
