.env.production.sample

# This is a sample configuration file. You can generate your configuration
# with the `bundle exec rails 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
