我正在尝试构建带有超音速的cron的对接映像，它可以从我的apache服务器获取日志并运行容器，但是它失败了，有人能帮我解决这个问题吗?因为cron容器被阻止了，所以不能站起来。

这是码头文件

代码语言：javascript
复制
FROM php:7.4 as cron
RUN apt-get update && apt-get install -y cron
#Run the echo
RUN echo "* * * * * root php /var/www/artisan schedule:run >> /var/log/cron.log 2>&1" >> /etc/crontab
USER root
ENV SUPERCRONIC_URL=https://github.com/aptible/supercronic/releases/download/v0.1.12/supercronic-linux-amd64 \
    SUPERCRONIC=supercronic-linux-amd64 \
    SUPERCRONIC_SHA1SUM=048b95b48b708983effb2e5c935a1ef8483d9e3e
RUN curl -fsSLO "$SUPERCRONIC_URL" \
 && echo "${SUPERCRONIC_SHA1SUM}  ${SUPERCRONIC}" | sha1sum -c - \
 && chmod +x "$SUPERCRONIC" \
 && mv "$SUPERCRONIC" "/usr/local/bin/${SUPERCRONIC}" \
 && ln -s "/usr/local/bin/${SUPERCRONIC}" /usr/local/bin/supercronic
#Create the log file to be able to run taild
RUN touch /var/log/cron.log
EXPOSE 9000
CMD bash -c "cron && php-fpm"

当您在容器顶部运行supercronic时，您需要检查您的坞映像，并覆盖您的入口点来启动php映像和supercronic。

它可能会在启动过程中发生冲突，而您的超级管理人员可能会在启动过程中失败。

代码语言：javascript

     Docker entry:
     ENTRYPOINT  /var/user/docker-entrypoint.sh

您可以创建入口点文件，并首先使用supercron启动这两个条目。
