如何将参数传递给docker-compose.yml中的Dockerfile

我有一个具有以下（简化）结构的项目

apkmirror

：

.
├── docker-compose.yml
└── tor
    └── Dockerfile

docker compose.yml

version: '3'

services: 
  tor:
    build:
      context: ./tor
      args:
        password: ""
    ports:
      - "9050:9050"
      - "9051:9051"

tor
目录中的
Dockerfile
是：

FROM alpine:latest
EXPOSE 9050 9051
ARG password
RUN apk --update add tor
RUN echo "ControlPort 9051" >> /etc/tor/torrc
RUN echo "HashedControlPassword $(tor --quiet --hash-password $password)" >> /etc/tor/torrc
CMD ["tor"]

我试图将参数
password
作为值
”
（一个emtpy字符串）传递到
Dockerfile
，以便它可以使用Tor对其进行散列，并将
HashedControlPassword
行添加到配置文件（参见）

但是，如果I
docker compose build
后跟
docker compose up
，则日志包含以下内容：

换句话说，
password
参数没有被“拾取”：Tor说它没有“值”。但是，与上的示例相比，我看不出
docker compose.yml
或
Dockerfile
有什么问题

有人能发现问题出在哪里吗？
我相信问题出在密码是空字符串。如果我将其替换为
“foo”
，则
docker compose up
似乎按预期工作。
