Create a self signed certificate

There are probably better ways, but it does the trick for a self hosted nextcloud deployment.

OUT="$(ip route | grep default | cut -d ' ' -f 3)"
PORT='443'
openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes \
  -keyout server.key -out server.crt -subj "/CN=$OUT:$PORT" \
  -addext "subjectAltName=DNS:$OUT,DNS:localhost,IP:127.0.0.1"
