我该如何解决"crontab: your UID isn't in the passwd file. bailing out."？

Question

您好，我正在使用 Docker 和 whenever 编写 cron 计划规则，但是当我在我的 docker 容器中运行 whenever --update-crontab 时出现此错误正在给我看。

crontab: your UID isn't in the passwd file.
bailing out.
[fail] Couldn't write crontab; try running `whenever' with no options to ensure your schedule file is valid.

Docker文件

FROM ruby:2.4.1-slim
RUN apt-get update && apt-get -y install cron
ENV RAILS_ENV production

ENV INSTALL_PATH /app

RUN mkdir -p $INSTALL_PATH
WORKDIR $INSTALL_PATH


COPY Gemfile Gemfile.lock ./
RUN bundle install --binstubs --jobs 20 --retry 5

COPY . .
RUN chown -R nobody:nogroup /app
USER nobody

# use docker run -it --entrypoint="" demo "ls -la" to skip
EXPOSE 3000

CMD puma -C config/puma.rb

Docker版本：Docker version 17.05.0-ce, build 89658be

我的Docker撰写文件

  chatbot_web:
    container_name: chatbot_web
    depends_on:
      - postgres
      - chatbot_redis
      - chatbot_lita
    user: "1000:1000"
    build: .
    image: dpe/chatbot
    ports:
      - '3000:3000'
    volumes:
      - '.:/app'
    restart: always

我该如何解决这个问题？

编辑： 当我使用：

host$ docker run -it dpe/chatbot bash
container $ whenever --update-cron
[write] crontab file updated

有效，但当我使用时：

host$ docker exec -it chatbot_web bash                                                                                                                                                                                               
I have no name!@352c6a7500d2:/app$ whenever --update-cron
crontab: your UID isn't in the passwd file.

为了修复，我在 Dockerfile 和 docker-compose

中使用相同的用户

Docker文件

RUN chown -R nobody:nogroup /app
USER nobody

Docker撰写

  chatbot_web:
    user: "nobody:nogroup"

我该如何解决"crontab: your UID isn't in the passwd file. bailing out."？
