             Summary: Make Flink configuration properties available as env vars in Docker image
                 Key: FLINK-6572
                 URL: https://issues.apache.org/jira/browse/FLINK-6572
             Project: Flink
          Issue Type: Improvement
          Components: Docker
    Affects Versions: 1.2.1
            Reporter: Joshua Griffith
            Priority: Minor


We run Flink in containers in production and it has been convenient to have all of Flink's configuration options available as environment variables so a separate configuration volume is not required. In our image we [grab the options from the config documentation|https://github.com/orgsync/docker-flink/blob/2abc0bf2b93238e4d1895d4ada0e8f6a72b577cf/Dockerfile#L33-L40] and [load them into the configuration file in the entrypoint|https://github.com/orgsync/docker-flink/blob/2abc0bf2b93238e4d1895d4ada0e8f6a72b577cf/entrypoint.sh#L32-L50]. While this method is not ideal, I think this feature would be useful in the official Docker image.
