Does anybody have advice or a link to a tutorial regarding hosting multiple Ghost sites on a single DigitalOcean droplet?
I’m currently running a dozen Ghost sites, with each on a separate droplet. I use the official Ghost install on the DigitalOcean marketplace whenever creating a new Ghost site. It makes the initial setup a breeze.
But the cost of running multiple droplets really adds up. So I’m wondering whether I can host all of these sites on a single (larger) droplet? Preferably, without too much hassle 
I’ve heard of terms like “containerization” but my experience with server admin or infrastructure is not at an advanced level.
Any advice, links or recommendations would be greatly appreciated.
