如何在官方 Redmine Docker 镜像中设置 cron 作业来发送提醒电子邮件？

在基于Docker Hub 上的官方镜像，我正在尝试设置一个 cron 作业来定期发送提醒电子邮件。

按照指示这里，在容器内输入bundle exec rake redmine:send_reminders RAILS_ENV=productionas可以正常工作。但是，使用设置相同的命令不起作用并输出各种错误消息。我怀疑它们与Bundler 或 rake 的正确设置有关，但由于不熟悉 Ruby 应用程序，我现在完全不知所措。我甚至尝试添加（看似）相关的环境变量，以便：rootcrontab -ePATHcrontab

PATH=/usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
RUBY_MAJOR=2.6
RUBY_VERSION=2.6.5
RUBY_DOWNLOAD_SHA256=d5d6da717fd48524596f9b78ac5a2eeb9691753da5c06923a6c31190abe01a62
GEM_HOME=/usr/local/bundle
BUNDLE_SILENCE_ROOT_WARNING=1
BUNDLE_APP_CONFIG=/usr/local/bundle
RAILS_ENV=production
HOME=/home/redmine
REDMINE_VERSION=4.1.0

但至今无果。

以下是我crontab -e迄今为止尝试添加的内容。每个命令（当然）前面都有 cron 的日期时间字符串格式，后面跟着用于> /var/log/myjob.log 2>&1记录其输出的内容。

正确的命令是什么？

答案1

事实证明克伦德包括在忙碌盒子bundle exec rake...可以毫无问题地运行命令。也许它处理环境变量的方式与标准 crond 不同？

我所要做的就是

apt-get install busybox-static
busybox crontab -e

然后将以下作业添加到 crontab 的列表中。

0 7 * * 1-5 cd /usr/src/redmine; bundle exec rake redmine:send_reminders RAILS_ENV=production

请注意，目前，这些步骤是在正在运行的 Redmine 容器内手动完成的。我Dockerfile稍后会添加这些内容。
