Refresh the Docker image?

[jakegigaom]

Is it possible for someone to refresh the Docker image with the latest repo? When I deploy in Kubernetes using the provided Helm chart, the image: openmessaging/openmessaging-benchmark:latest yaml files are different and appear to be an older specification than the current ones in the repo.

For example:
Repo: driver-pulsar/pulsar.yaml, line 29:
clusterName: local namespacePrefix: benchmark/ns

Pod: driver-pulsar/pulsar.yaml
namespacePrefix: benchmark/local/ns
