Pass argument to docker compose

Question

In my docker compose file there is a dynamic field which I\'d like to generate during the running. Actually it is a string template:

environment:
    - SERVE         


        

Answer 1

You can use the flag when using docker-compose build

docker-compose build --build-arg PRODUCTION=VALUE

In Dockerfile you can get the argument PRODUCTION

# Dockerfile
ARG PRODUCTION
FROM node:latest
