I googled more time but lost. Expecting an answer or ideas to solve this.

cf restart-app-instance helps for restarts but I have to restage for environment variable updates.

Is there any way to do instance level restage in Cloudfoundry?

PS: I even checked if there any clone option scale up and scale down original without downtime but no luck either.

We used this particular plugin https://github.com/orange-cloudfoundry/cf-plugin-bg-restage .

bg-restage will not give any downtime .

https://plugins.cloudfoundry.org/

Perform a zero-downtime restage of an application over the top of an old one (highly inspired by autopilot)

install:
cf install-plugin -r CF-Community "bg-restage"
company:Orange
homepage:https://github.com/orange-cloudfoundry/cf-plugin-bg-restage
author:Arthur Halet - arthur.halet@orange.com
platforms:osx , win64 , win32 , linux64 , linux32

cf bg-restage is mostly for those who don't want to redeploy an app with source code. It was initially created to restage automatically all apps in a Cloud Foundry when a new buildpack has been released with security patch.

The best way to achieve this is to do a blue-green deployment. https://docs.cloudfoundry.org/devguide/deploy-apps/blue-green.html

  • Yes, we use BLUE GREEN deployment but this is a different scenario. thanks anyways! – jhulfikarali Dec 07 '18 at 23:19
  • The question is titled "Restage an application without downtime", blue green is currently the best way to do that. There is an experimental feature that also addresses this too :- https://docs.cloudfoundry.org/devguide/deploy-apps/zero-downtime.html – Dan Higham Dec 10 '18 at 00:54
