[BUG] Can't escape interpolation

[slaskis]

Expected Behavior

Expect $$REDIS_PASSWORD to be interpolated according to the compose spec so into $REDIS_PASSWORD.

Actual Behavior

It interpolated it into $(REDIS)_PASSWORD.

Steps To Reproduce

1. Run kompose convert
2. Look into the "redis-deployment.yaml" file and see $$REDIS_PASSWORD being interpolated as $(REDIS)_PASSWORD

Kompose Version

1.34.0 (HEAD)

Docker-Compose file

services:
  redis:
    image: redis
    command: redis-server --requirepass $$REDIS_PASSWORD
    ports:
      - 6379

Anything else?

No response

An interesting observation is that the healthcheck test seems to interpolate it correctly:

services:
  redis:
    image: redis
    command: redis-server --requirepass $$REDIS_PASSWORD
    healthcheck:
      test: redis-cli -a $$REDIS_PASSWORD --raw incr ping
    ports:
      - 6379
