# This is a sample configuration file. You can generate your configuration # with the `rake mastodon:setup` interactive setup wizard, but to customize # your setup even further, you'll need to edit it manually. This sample does # not demonstrate all available configuration options. Please look at # https://docs.joinmastodon.org/admin/config/ for the full documentation. # Note that this file accepts slightly different syntax depending on whether # you are using `docker-compose` or not. In particular, if you use # `docker-compose`, the value of each declared variable will be taken verbatim, # including surrounding quotes. # See: https://github.com/mastodon/mastodon/issues/16895 # Federation # ---------- # This identifies your server and cannot be changed safely later # ---------- LOCAL_DOMAIN=example.com # Use this only if you need to run mastodon on a different domain than the one used for federation. # You can read more about this option on https://docs.joinmastodon.org/admin/config/#web-domain # DO *NOT* USE THIS UNLESS YOU KNOW *EXACTLY* WHAT YOU ARE DOING. # WEB_DOMAIN=mastodon.example.com # Use this if you want to have several aliases handler@example1.com # handler@example2.com etc. for the same user.
