ShinyProxy Long-Task Container Management: How to Keep Containers Running After Browser Closure Until Computation Completes?

[iBelen]

Hello, fellow technical colleagues~

I’d like to consult a technical issue regarding container management with ShinyProxy.

We currently face two scenarios:

Short-term tasks: Some applications have a short runtime and are fully managed by ShinyProxy for their lifecycle — when users close the browser, the Docker container is automatically triggered to shut down. (This works perfectly with ShinyProxy.)
Long-term tasks: Other applications involve extremely time-consuming computations. Users may close the browser before the task completes (to avoid waiting), but the container needs to keep running until the computation finishes, then shut down automatically.

Could you please advise on implementing the following requirements:

Differentiate between task types and customize a strategy for long-term tasks to “maintain container operation after browser closure”.
Automatically trigger container shutdown after the computation completes.

Thank you.

hey iBelen,
where are you hosting shinyproxy? is there somewhere else where you can queue a job independent to your app?

also per app i think there is a heartbeat-timeout: -1 which will disable it. it will run forever or until admin stops it

Hi, as @damianslee mentioned you can configure the hearbteat timeout to prevent apps from automatically being stopped. See also the examples here: https://github.com/openanalytics/shinyproxy-config-examples/tree/master/10-background-apps
It's then also a good idea to enable the my-apps option (see https://shinyproxy.io/documentation/ui/ ) such that users can easily re-open their running apps.

There is currently no way to automatically stop an app after a computation has finished. This is something we would like to implement. Maybe it will be part of a future release. If this is important for you, you could consider sponsoring this, see https://shinyproxy.io/support/

嗨，因为@damianslee提到可以配置hearbteat超时，以防止应用程序自动停止。另请参阅此处的示例：https://github.com/openanalytics/shinyproxy-config-examples/tree/master/10-background-apps然后启用`my-apps`选项（见https://shinyproxy.io/documentation/ui/）也是一个好主意，这样用户可以轻松地重新打开正在运行的应用程序。>>目前没有办法在计算完成后自动停止应用程序。这是我们想要实施的事情。也许它将成为未来发布的一部分。如果这对你来说很重要，你可以考虑赞助这个，见https://shinyproxy.io/support/

非常感谢
