Disable redis persistence in docker

Question

According to this link, persistence of redis instances can be prevented by setting --save ''. However when I try to use that argument in my docker-compose.yml the redis instance still loads a database from disk and persists all data:

version: '3'
services:
  redis:
    image: "redis:alpine"
    command: ["redis-server", "--save"]  # disable persistence
    ports:
      - "7777:6379"

I also tried command: ["redis-server", "--save", ""] but problem preserves.

How can I enforce non-persistence (empty redis on every restart)?

For me work

command: redis-server --save "" --appendonly no
image: redis:alpine
