Remove docker image old version

Hi,

I have a question about docker images. through a scenario, I activate a machine learning flow that returns the classification results and pushes the model to be deployed directly to the deployer API. If a subsequent run of the scenario reports a model that performs better, this new model will also be pushed to the API deployer. At this point, I'll manually update the service with the new model in the API deployer section.

Everything works, but I realize that the image of the old version remains inside the docker memory and this affects the VM memory a lot (I specify the path of the weighted folder: var / lib / docker / overlay2).

with manual deletion, via the docker command, it is possible to solve the problem, but I would like to know if there was a way to be able to delete the images directly from dataiku, or if there was a way to perform the deletion at the time of update of the new version.

I tried the "delete old images" macro, but as the images keep the tag, they are not deleted.

thanks a lot
