teach yourself linux ... rent a remote linux server ( VPS ) on say ovh.com or any vps hosting provider ... learn how to spin up a server on a cloud provider ( aws, google cloud ) ... pickup containers like docker ... learn TLS cert as well as DNS registrar ... on a DNS registrar get yourself a toy domain name like myname.com ... write a tiny server in golang then bundle it into a docker container which you execute on a remote cloud provider ... define the IP of remote host to link to the DNS of your domain name so you are able to enter into a browser this domain url so your browser now talks to your own server you just deployed ... do this manually then learn programming ( golang and bash ) so you can automate all of above steps
