docker - 在heroku上为docker dyno运行一次性命令

Question

当我从 cli 或 scheduler 附加组件运行工作人员测功机时，什么也没有发生。

我试图启用或禁用测功机，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所示:

2019-09-04T18:30:34.176982+00:00 heroku[scheduler.8210]: State changed from starting to complete

启用测功机后运行的日志输出如下:

最后一个是预期的行为。

我正在尝试像这样运行它:

heroku run worker

像这样:

heroku run worker /opt/app/run.sh

调度程序命令简单地指定为: worker 。

我应该怎么做才能在heroku中一次性运行docker容器？

Answer 1

好吧，正如我发现的那样，我做错了一切。
从 cli 一次性运行需要指定进程类型作为参数:

heroku run worker --type=worker

至于 scheduler插件，它仅适用于 web如文档中所述的测功机:

If you are using Heroku Scheduler and Container Registry as your deployment method, your task must be accessible from the web image. There is no way to specify a non-web image for task execution.
