如何让PHP-CLI容器在不需要任何PHP脚本的情况下运行？
我一直在尝试使用Docker和Docker Compose构build一个PHP cli容器，并且希望保持活动状态，而不需要在其中运行任何PHP脚本。
我已经尝试了我自己的Dockerfile ：
FROM ubuntu:16.04 ENV PATH="/root/.composer/vendor/bin:${PATH}" RUN apt-get update && \ apt-get -y -qq install software-properties-common \ xvfb \ locales && \ locale-gen en_US.UTF-8 && \ export LC_ALL=en_US.UTF-8 && \ export LANG=en_US.UTF-8 && \ add-apt-repository ppa:ondrej/php && \ apt-get update && \ DEBIAN_FRONTEND=noninteractive apt-get -y --allow-unauthenticated install \ php7.1-curl \ php7.1-cli \ php7.1-bcmath \ php7.1-json \ php7.1-intl \ php7.1-mbstring \ php7.1-mcrypt \ php7.1-mysql \ php7.1-xml \ php7.1-xsl \ php7.1-zip \ curl \ git \ wget \ pkg-config && \ apt-get clean && \ apt-get autoremove && \ rm -rf /var/lib/apt/lists/* COPY config / RUN sh /usr/local/bin/install.sh ENTRYPOINT bash -C '/entrypoint.sh';'bash' CMD ["php", "-a"]
还有另一个（从主要的PHP图像扩展）：
FROM php:7-cli-alpine ENV PATH="/root/.composer/vendor/bin:${PATH}" COPY config / RUN sh /usr/local/bin/install.sh WORKDIR /var/wwww CMD ["php", "-a"]
docker-compose.yml只有这个：
version: '3.3' services: webserver: build: context: . restart: on-failure env_file: .env environment: UID: ${UID} GID: ${GID}
最后，如果你想尝试一下， 这里是一切的完整仓库。
问题是什么？ 通过运行docker-compose up --build --force-recreate构build容器docker-compose up --build --force-recreate用代码0退出，但是docker-composer logs没有任何帮助，因为它什么都没说。
看看命令行中的以下输出（对于这篇文章中的第二个Dockerfile，对于第一个和更多的东西几乎是一样的）：

如何保持容器运行而不需要运行PHP脚本？
注意：你可能会问，为什么不build立
php-fpm|apache但是我不需要任何web服务器，因为容器只用于命令行项目（这是一个WIP）
你正在运行php -a这是一个REPL，它需要交互式的TTY。 所以你需要启用你的撰写
version: '3.3' services: webserver: build: context: . restart: on-failure env_file: .env environment: UID: ${UID} GID: ${GID} tty: true stdin_open: true
后来如果你需要附加到它来运行命令，你将需要使用docker
docker attach <containernameOrID>
