Phoenix and Let's Encrypt
Yesterday I was using this post as reference to setup SSL certs to run a Elixir/Phoenix app and after struggle a little bit trying to serve the
.well-known folder without nginx (or apache/etc), I found a simple solution:
certbot-auto certonly --webroot -w /path/to/my/app/_build/prod/lib/my_app/priv/static/ -d www.myappdomain.com
Setting the webroot directly to the
_build dir allowed me to serve
.well-known running the app in prod mode and without the need to change any code and/or restart the app.
