This makes all containers (except mautrix-telegram and mautrix-whatsapp), start as a non-root user. We do this, because we don't trust some of the images. In any case, we'd rather not trust ALL images and avoid giving `root` access at all. We can't be sure they would drop privileges or what they might do before they do it. Because Postfix doesn't support running as non-root, it had to be replaced by an Exim mail server. The matrix-nginx-proxy nginx container image is patched up (by replacing its main configuration) so that it can work as non-root. It seems like there's no other good image that we can use and that is up-to-date (https://hub.docker.com/r/nginxinc/nginx-unprivileged is outdated). Likewise for riot-web (https://hub.docker.com/r/bubuntux/riot-web/), we patch it up ourselves when starting (replacing the main nginx configuration). Ideally, it would be fixed upstream so we can simplify.

# This is a custom nginx configuration file that we use in the container (instead of the default one),
|
|
# because it allows us to run nginx with a non-root user.
|
|
#
|
|
# For this to work, the default vhost file (`/etc/nginx/conf.d/default.conf`) also needs to be removed.
|
|
#
|
|
# The following changes have been done compared to a default nginx configuration file:
|
|
# - various temp paths are changed to `/tmp`, so that a non-root user can write to them
|
|
# - the `user` directive was removed, as we don't want nginx to switch users
