pleroma/installation/pleroma-mediaproxy.nginx

# This file is for those who want to serve uploaded media and media proxy over
# another domain. This is STRONGLY RECOMMENDED.
# This is meant to be used ALONG WITH `pleroma.nginx`.

# If this is a new instance, replace the `location ~ ^/(media|proxy)` section in
# `pleroma.nginx` with the following to completely disable access to media from the main domain:
# location ~ ^/(media|proxy) {
#     return 404;
# }
#
# If you are configuring an existing instance to use another domain
# for media, you will want to keep redirecting all existing local media to the new domain
# so already-uploaded media will not break.
# Replace the `location ~ ^/(media|proxy)` section in `pleroma.nginx` with the following:
#
# location /media {
#     return 301 https://some.other.domain$request_uri;
# }
#
# location /proxy {
#     return 404;
# }

    # Uncomment this if you need to use the 'webroot' method with certbot. Make sure
    # that the directory exists and that it is accessible by the webserver. If you followed
    # the guide, you already ran 'mkdir -p /var/lib/letsencrypt' to create the folder.
    # You may need to load this file with the ssl server block commented out, run certbot
    # to get the certificate, and then uncomment it.
