Docker - Override or remove ENTRYPOINT from a base image

Set ENTRYPOINT to /usr/bin/env. Then set CMD to be what you want run.

Graham's idea above worked pretty well. Thanks again!

For future reference, here is the two lines I had to add to my Dockerfile:

ENTRYPOINT ["/usr/bin/env"]

CMD ["bash", "/opt/gatling/trigger-test-and-parse-result.sh"]
