I'm using an Instance of Ubuntu 16.04 lts on Google to run a store, but I'd like to point to my domain. Wich line on Apache2 should I update?
You'll have to update your
web/secure/base_url paths in
Then clear the cache by below command.
sudo rm -rf var/cache var/generation var/page_cache
Also you may also need to point your virtual hosts to current domain.
