Depends on whether the change can be consumed directly by app or by
buildpack and other stuff things.

If the buildpack needs to read that variable and take some action like for
your agent activation or change stuff like memory or jvm arguments, then
restage, otherwise just restart is fine.

Thanks for the reply!

Lets say, if I add evn variables to the application. In order for the
application to use those env variables which are set using cf-setenv, do I
need to restart or restage the application ?

The staging process has access to env variables, etc. so the env can
affect the contents of the droplet.

You might notice that when you do a cf set-env you get a message that
advises you to do a cf restage. Because CF doesn't know whether your
buildpack is affected by env changes, it recommends the more extreme option.

For some (many) apps, a cf restart would be sufficient.

`restage` will stop your application, run the application bits through
the staging process to create a new droplet, and then start the new
droplet. It's a lot like `push` but without actually pushing new
application bits.

`restart` will simply stop your application and start it with the
existing droplet.

You typically restart when you need your applicaiton's environment
refreshed and you typically restage when you need/want the buildpack to run
without updating the application source.

Hope that helps.

Hi,

Can someone explain in detail what is the difference between cf restart
and cf restage ?
