How to tag an image in a Dockerfile? [duplicate]

June 15, 2023 by Tarik

Unfortunately it is not possible. You can use build.sh script, which contains like this:

#!/usr/bin/env bash
if [ $# -eq 0 ]
  then
    tag='latest'
  else
    tag=$1
fi

docker build -t project:$tag .

Run ./build.sh for creating image project:latest or run ./build.sh your_tag to specify image tag.
