# Really dirty backwards compatible workaround for single server portals:
# =======================================================================
# in the past we used to require single server portals not to include
# server domain env variable because it messed up with caddy; we switched
# to certbot and that is not the case any more but we also switched to
# using built in envsubst instead of custom mustache script for nginx
# templating and now when server domain is not defined, it messes up whole
# nginx config and nginx will not start; this workaround assigns portal
# domain as a server domain if server domain is not defined
