First, I asked you to build the image for our project from scratch and tag it as Docker-image-demo2.3.3. You can do this using the Docker build command with the no cache option. Then add the T flag and the name of your image, which is your username/docker-image-demo:2.3.3 . Docker will re-execute every Dockerfile instruction from scratch, ignoring any existing cached layers.
