How to change image version dynamically?

Question

Docker

Is it possible to set an image tag in .enva file and pass it to a Dockerfile?
I'm thinking of doing it via docker-compose arguments

# docker-compose
version: '3.5'
services:
  foo:
    build:
      context: .
      args:
        label: ${FOO_TAG}

# dockerfile
FROM foo:${label}

But I found out that the arguments are passed to RUN and that's not how it works.. Is there any other way to do this?

Answer 1

Before FROM we write ARG FOO_TAG
