Docker compose on ecr: ERROR: No such service: --build-arg

Question

I try to pass arg into the docker build process in this command:

docker-compose -f .docker/docker-compose.ecr.yml build my-app --build-arg BUILD_VERSION=5.0.0

But I got error:

ERROR: No such service: --build-arg

According to the docs docker-compose have build-arg parameter.

The yml file:

version: '3'

services:
  my-app:
    image: 3144.dkr.ecr.us-east-2.amazonaws.com/my-app:latest
    build:
      context: ../
      dockerfile: ./.docker/Dockerfile

What can be the problem?

Answer 1

The services should be last in the command line.

$ docker-compose build --help
Usage: build [options] [--build-arg key=val...] [SERVICE...]

So:

$ docker-compose -f .docker/docker-compose.ecr.yml build --build-arg BUILD_VERSION=5.0.0 my-app 

Answer 2

I had a similar issue but it was Visual Studio 2019 that was trying to publish and putting the build my-app before the 'build-arg' parameter.

All I had to do is to update VS 2019 to the latest version 16.11.0 that solved this error during the publish from the IDE.
