【问题描述】：
当我从 cli 或 scheduler 附加组件运行工人测功机时，什么也没有发生。
我尝试启用或禁用测功机，但它对一次性和调度程序没有任何作用。
启用 dyno 时，heroku 会启动它（不是一次性或调度程序），并且来自 worker 的命令（在 Dockerfile 中指定为 CMD）运行得很好。
使用命令运行 run 也无济于事。
此类运行的日志输出如下：
2019-09-04T18:30:34.176982+00:00 heroku[scheduler.8210]: State changed from starting to complete

启用测功机后的运行日志输出如下：

最后一个是预期行为。
我正在尝试这样运行它：
heroku run worker
像这样：
heroku run worker /opt/app/run.sh
调度程序命令指定为：worker。
我应该怎么做才能在 heroku 中一次性运行 docker 容器？
