docker-size - a litle script to calculate the size of an image or container

[gfjardim]

Well, this is a small script I use to calculate the final size of an image or container.

 

#!/bin/bash
docker history $1 1>/dev/null 2>&1
if [[ $? -eq 0 ]]; then
  docker save $1 | dd of=/dev/null
else
  docker export  $1 | dd of=/dev/null
fi

 

Usage: docker-size <IMAGE | CONTAINER>
