Subdomain / DNS records setup on a single Ubuntu 18.04 droplet running with Django, Postgres, Nginx, Gunicorn
When I first created an Ubuntu 18.04 droplet I used domain name as www.example.com and successfully completed all the steps documented here
and I did not use www.example.com, dev.example.com and example.com any where in any of the steps. I only used IP address.
Since my requirement is to use this droplet only for subdomain, I changed domain name from www.example.com to ‘dev.example.com’.
My requirement is to setup another droplet for production to launch the site with domain name ’www.example.com’.
Now I need to install 'TLS/SSL certificates’ by following steps documented here
But I need to setup all DNS records required for subdomain 'dev.example.com’ so that we can use this domain during development of the application.
Note: the domain name 'example.com’ is registered with godaddy and I already pointed DO nameservers for this domain.
Could someone point right steps for adding DNS records for both main and subdomains to achieve my requirement.
