Part of implementing discourse I have configured app.yml file as per the instruction from github [page](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md). Discourse is working fine. However Later I realized that there was spelling mistake in mail id that I provided and I am stuck as the admin account registration intimation will be sent to this email id.

Should I rebuild the docker image once again for changing mail ID ? Or is there any other options available ?

Change the setting in `app.yml` and rebuild, yes.

```plaintext
./launcher destroy app
./launcher start app

```

should do the trick, but rebuild is safest
