linux - Cronjob 不执行“bundle exec rake -f ...”

Question

我正在尝试使用 cronjob 在 docker 容器中通过电子邮件自动创建 redmine 的问题。我使用了官方 redmine docker 镜像的略微修改版本，安装了 cron 和一些额外的环境变量。手动，当我在终端中运行以下行时，一切正常。

# cd /usr/src/redmine && bundle exec rake -f /usr/src/redmine/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=$IMAP_HOST port=$IMAP_PORT ssl=1 username=$SMTP_USER password=$SMTP_PASSWORD -r "openssl" -E "OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE"

(eval):1: warning: already initialized constant OpenSSL::SSL::VERIFY_PEER

现在，我想创建一个执行这一行的 cronjob，比如说每分钟。我在下面添加了 cronjob，但仍然没有预期的结果。

# crontab -l
* * * * * cd /usr/src/redmine && bundle exec rake -f /usr/src/redmine/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=$IMAP_HOST port=$IMAP_PORT ssl=1 username=$SMTP_USER password=$SMTP_PASSWORD -r "openssl" -E "OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE"

从/var/log/cron.log我知道的文件中，cronjob 已执行。

Dec 11 14:43:01 26c0ec148cea CRON[155]: (root) CMD (cd /usr/src/redmine && bundle exec rake -f /usr/src/redmine/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=$IMAP_HOST port=$IMAP_PORT ssl=1 username=$SMTP_USER password=$SMTP_PASSWORD -r "openssl" -E "OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE")

如果我附加&> /home/redmine/cron.log到作业，则会创建一个空文件。我假设 cron 以某种方式破坏了命令。

我已经尝试使用bundle( /usr/local/bin/bundle) 和rake( /usr/local/bundle/bin/rake) 的完整路径但没有成功。你能帮我修复这个 cronjob 或者告诉我如何进一步调试吗？
