Nextcloud 17 docker and nginx reverse proxy

sigh sometimes I hate this adminstration stuff but it was necessary as I'm migrating stuff to containerd version. This time I choosed to spend my time in migrating my existing nextcloud installation to the docker version (and upgrading during this process (everytime a great idea)). However I ended up in a running version but I could not connect from my apps because the new authorization process stuck in calling /login/v2/poll. After googling around I found one little thing and that's this entry which has to be added to the config.php file which can be found in the mounted volume of the nextcloud container:

'overwriteprotocol' => 'https',

It's simply forcing the nextcloud to use https in the given URLs instead of http. To have it complete, here's my nginx reverse proxy configuration:

server {
  listen 80;
  server_name your_host_name;
  # enforce https
  return 301 https://$server_name$request_uri;

server {
  listen 443 ssl;
  server_name your_host_name;

	ssl_certificate /etc/letsencrypt/fullchain.pem;
	ssl_certificate_key /etc/letsencrypt/privkey.pem;

    location / {
		proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_redirect off;
        proxy_buffering off;

        proxy_pass http://localhost:8080;

Yep it's not the philosopher's stone but maybe it prevents others from searching around and waste time.
