continuous deployment - How to shutdown an app deployed on Heroku?

Question

I have an app on Heroku which is being used by few users. However, I notice there are some data issues which I'd like to fix and stop the app in the mean time so users don't enter anything new.

Is there a way to stop the app on Heroku rather than destroying it? I see that restart server command is there... Although I don't see anything like 'stop'.

Answer 1

To completely 'stop' your app you can scale the web dynos down to zero which effectively takes all your app http-processes offline.

$ heroku ps:scale web=0
Scaling web processes... done, now running 0
