First build your docker image by changing directory to kserve/python and replacing dockeruser with your docker username in the snippet below.

docker build -t dockeruser/artserver:latest -f artexplainer.Dockerfile .

Then push your docker image to your dockerhub repo

docker push dockeruser/artserver:latest

Once your docker image is pushed you can pull the image from dockeruser/artserver:latest when deploying an inferenceservice by specifying the image in the yaml file.
