How to use docker-ce under my ubuntu / Digital Ocean?

Hi all,
Using docker-ce for lamp apps I got url like http://127.0.0.1:8084/ and it works under my local ubuntu 18. I need to install docker-ce under my ubuntu 16 on Digital Ocean with hosting which I created in https://my.freenom.com

Are there some addons/instructions how can I do it ?

Thanks!

Have tried to google for “docker-ce ubuntu install”?

Sure, when I installed docker under my local server.
but I did not find how to install with with hosting
please give link

Searching in net I found this https://github.com/nginx-proxy/nginx-proxy
extention, but my docker apps are based on apache.
Are there something like that, but for apache?
