Docker vs direct install

HI All,

I am about to attempt my first mattermost install. I have a DigitalOcean droplet that is used to host another site, and plan to host many sites on it. What I'm wondering is whether there is serious advantage to using Docker other than convenience? As I'd like to have many sites running on the droplet eventually, I am interested in keeping it as lean and efficient as possible.

So I am leaning towards installing without docker, but is this something I will regret?

Thanks,
Chris
