Getting Started

Prerequisites

A) Domain Name

During installation, you'll be asked to point a wildcard DNS entry to your Captain IP Address. If you need help with domain name, see Domain and DNS. This will cost you as low as $2 a year.

B) Server with a Public IP

Captain has to be installed on a machine with a public IP address. If you need help with Public IP, see Server & Public IP address. This will cost you as low as $5 a month. If you use the DigitalOcean referral code, you'll get $10 credit - two months worth of free server: https://m.do.co/c/6410aa23d3f3

Note that you can install Captain on your laptop which is behind NAT (your router) for testing purposes, but it requires some special setup, like port forwarding.

C) Install Docker on Server (at least, version 17.06.x)

If you get your server from DigitalOcean, you can select a server with "pre-installed Docker". This will be the easiest option. Otherwise, you can install Docker CE by following this instruction: https://docs.docker.com/engine/installation
