在shinyapps.io上睡觉shinyapp

Question

How do I 'awaken' a sleeping shinyapp on shinyapps.io?

I have tried terminating and then (re)deploying. This does not work.

Answer 1

我认为睡觉的shinyapp会在有人使用时自动唤醒。

Answer 2

Active hours are the number of hours that your application is up and serving requests. If you have one or one hundred people using your Shiny app for an hour, you are still only using one active hour. When an application hasn't received any traffic for some time (the idle period) it will put itself to sleep which stops the active hour counter from accruing. When a user requests an application, shinyapps.io will “wake up” your application so that it is running and capable of servicing the request.

From this , it would be helpful.

Answer 3

That is my experience too. As soon as someone navigates to the application URL the application changes state from 'sleeping' to 'running'.

Answer 4

Similar issue: I was having trouble understanding why directory index pages weren't loading when the applications were asleep.

Our structure:

<server>:<port>/
                shiny_s/
                        <user1>/
                                <app1 folder>/app.R
                                <app2 folder>/app.R
                        <user2>/
                                <app1 folder>/app.R

etc.

If the applications are asleep, directing a browser to <server>:<port> shows that shiny server is running fine. But go to any directory index page (without an app.R in it... eg, <server>:<port>/shiny_s or <server>:<port>/shiny_s/<user> ) and the page doesn't load, returning err_empty_response after what feels like a 60 second timeout. However, go to the application folder: <server>:<port>/shiny_s/<user>/<application folder> and the application wakes, runs as expected, and the directory folders now load indices as expected.

Makes me wonder if there is a way to get shiny apps to wake when a user visits the directory index pages?
