# initially we would us on: [release] as well, the problem is that
# the code in clowder would not know what branch the code is in,
# and would not set the right version flags.

# This will run when:
# - when new code is pushed to master/develop to push the tags
#   latest and develop
# - when a pull request is created and updated  to make sure the
#   Dockerfile is still valid.
# To be able to push to dockerhub, this expects the following
# secrets to be set in the project:
# - DOCKERHUB_USERNAME : username that can push to the org
# - DOCKERHUB_PASSWORD : password asscoaited with the username
