How to give a name to an image in Dockerfile

Question

I know that I can give the image name when building a custom image, like this:

docker build -t sam/can:v2 . # Will be named sam/can:v2

I wanted to know if I can define the name of the image in Dockerfile, so I won't have to mention it in the docker build command?

Can anyone help me with this?

Thanks.

This needs to be done in your build command.Here is what you can try. 

You can  build a docker-compose.yml that will identify the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: sam/can:v2

I hope this is what you are looking for.
