Docker compose environment variable string interpreted as variable

Question

I have an issue with a string in my environment variables, where the string contains '$', which is interpreted as a variable.

My key in my docker compose looks like:

version: '3.9'

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - .:/code
    network_mode: "host"
    restart: on-failure
    environment:
      SECRET: "f(Tfdsgd7@fibk$EBE"

As you can see my secret contains $EBE (fake secret for example), which is interpreted when I run docker-compose docker-compose.yaml build as a variable instead of a string.

WARNING: The EBE variable is not set. Defaulting to a blank string.

How can I make sure the secret is entirely intepreted as a string?
