将参数传递给docker-compose

Question

Using version 3 of docker-compose.

docker-compose build MY_ARGUMENT=herro

How do I use this in the docker-compose.yml file?

States here https://docs.docker.com/compose/reference/overview/ that it is possible ([ARGS...]) but doesn't say anything else.

Answer 1

https://docs.docker.com/compose/environment-variables/

web:
environment:
- username=root

or you can specifiy a file

env_file:
 - ./Docker/api/api.env

or for just args

  args:
    buildno: 1

EXAMPLE 1

build: ./dir

   build:
    context: ./dir
    dockerfile: Dockerfile-alternate
    args:
      buildno: 1
