如何设置 cron 作业以在官方 Redmine Docker 映像中发送提醒电子邮件？

  • 772

在基于Docker Hub上的官方图像的 Redmine 容器中，我正在尝试设置一个 cron 作业以定期发送提醒电子邮件。

按照此处的说明，在容器内键入bundle exec rake redmine:send_reminders RAILS_ENV=productionas可以正常工作。root但是，设置相同的命令 usingcrontab -e不起作用并输出各种错误消息。我怀疑它们与PATH为 Bundler 或 rake 设置正确有关，但不熟悉 Ruby 应用程序我现在完全迷路了。我什至尝试将（看似）相关的环境变量添加到crontab：

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

但到目前为止无济于事。

以下是我crontab -e到目前为止尝试添加的内容。每个命令（当然）前面都是 cron 的日期时间字符串格式，后面是> /var/log/myjob.log 2>&1记录它输出的任何内容。

  • root cd /usr/src/redmine; bundle exec rake redmine:send_reminders RAILS_ENV=production
  • root cd /usr/src/redmine; /usr/local/bin/bundle exec /usr/local/bundle/bin/rake redmine:send_reminders RAILS_ENV=production

Could not locate Gemfile or .bundle/ directory

  • cd /usr/src/redmine; /usr/local/bin/bundle exec /usr/local/bundle/bin/rake redmine:send_reminders RAILS_ENV=production
  • /usr/src/redmine/remind.sh（以下脚本）

remind.sh

#!/bin/bash

bundle exec /usr/local/bundle/bin/rake redmine:send_reminders days=7 RAILS_ENV="production"

这是里面的东西/usr/src/redmine。存在一个名为的文件Gemfile。

什么是正确的命令？

cron redmine docker

    事实证明，BusyBox中包含的crond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？bundle exec rake...

    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，这些步骤是在运行的 Redmine 容器中手动完成的。我稍后会添加这些Dockerfile。
