You can use a docker-compose file using the target option:

version: '3.4'
services:
  img1:
    build:
      context: .
      target: img1
  img2:
    build:
      context: .
      target: img2

using your Dockerfile with the following content:

FROM alpine as img1
COPY file1.txt .

FROM alpine as img2
COPY file2.txt .
