Securing your Elrond validator + Netdata service behind nginx with self-signed SSL certificate on Ubuntu

Doing the following will ensure access to your node server is protected behind the firewall with the following URLs available:

https://<server ip>/node/* - you should see JSON output showing node stats (replace * with status, statistics, etc, see full list)
https://<server ip>/netdata - you will be prompted for the username and password you setup below, following which you should see your netdata dashboard

Setup the firewall:

To delete the container:

docker rm --force <container name>

To delete the image:

	create user user_name with encrypted password '...';
	grant connect on database "db-name" TO user_name;
	grant usage on schema public to user_name;
	grant select on all tables in schema public to user_name;
	alter default privileges in schema public grant select on tables to user_name;

	contract SimpleAccessControl {
