Makefile - append to command

I am writing a Makefile for my Docker app. I have make start-image, which starts the image with it's default command:

start-image:
  docker run name

I would like to have another command make do_something which would append the command that should be run within the docker container:

do_something:
  docker run name command args

How can I use the start-image command to do that?

Use a variable to store the common part of the commands

RUNTOOL=docker run name

start-image:
     ${RUNTOOL}

do-something:
     ${RUNTOOL} command args

With this strategy, it is also possible to build the RUNTOOL variable out of smaller parts to accomodate for more complex tasks.
