Environment variables interpolation not supported

[TheDogHusky]

Hey!

Just got my macbook pro, and decided to code my stuff on it with container compose.
The biggest issueI just came across is variable interpolation.

Here is the file:

services:
    redis:
        image: redis:7-alpine
        container_name: victoria-redis
        ports:
            - "6379:6379"
        command: ["redis-server", "--requirepass", "${REDIS_PASSWORD:-devpassword}"]
        env_file:
            - .env
        volumes:
            - redis_data:/data
        restart: unless-stopped

volumes:
    redis_data:

and .env:

REDIS_PASSWORD=mypassword

You would expect to be able to connect to redis://localhost:6379 with the password "mypassword" right?
Wrong! Unlike with docker, the password will be "${REDIS_PASSWORD:-devpassword} ", literally.

This has been a very annoying issue I came across.

Hoping it'll get fixed soon!

Cheers,
Adam
