  dbdata_redis:
    driver: local

  redis:
    image: redis:5.0.3-alpine
    ports:
      - 6379:6379
    volumes:
      - dbdata_redis:/data
    command:
      - --appendonly yes

This guide's documentation is really is misleading. I assumed that using Reactive Redis caused the Redis instance to be in-memory, like H2. As @zapjelly says, there is nothing in the documentation to indicate a seperate installation.
I see on Stack Overflow (Embedded Redis for Spring Boot) that there are embeddable Redis projects that could solve this.
