When specifying dockerfile as agent in a jenkins pipeline e.g. :

pipeline {
    agent {
        dockerfile {
            additionalBuildArgs '-t image_name:latest'
            label 'docker'

The docker pipeline plugin executes the following to build the image:

docker build -t 0c5e9a24b881c7c890b38ceb89cf26c5713e2c1e -t image_name:latest -f Dockerfile .

How can I disable automatically tagging the image? In this case I would like to have just one tag (image_name:latest).

Thanks a lot in advance!
