I used have Domain on the Dreamhost that is fully hosted on their VPS but I switch Digital Ocean for Postgress and root access. There is no tutorial for Dreamhost + Digital Ocean so I had to figure thing out myself and I'm no server admin.

I read the tutorial on GoDaddy and it's involve changing nameserver but on the Dreamhost, they said that I can't change nameserver and here is what they say: Non-editable DreamHost DNS records for example.com. These records were added automatically by DreamHost to provide services (such as web hosting or mail) which are active for this domain.

I can add DNS record type A point to my droplet IP but when I go to my website, I got Site Not Found from the dreamhost.
