i have installed discourse on vultr a year ago successfully only by following the official guide, now am thinking to go to digital ocean to do that again but i need to know few things.
1- am going with 8Gb ram plan do i need to do the swap ? i never did that with 4Gb plan on vultr.
2- do i have to start from installing docker or docker is already installed on the droplet ?
3- Please remind me again about this part as i don
t remember it ( ``` Hostname for your Discourse? [discourse.example.com]: ```) This means the top level domain ? i dont remember how i did it that time.
