Deploy nightscout onto an AWS EC2 instance

This repository contains the necessary files and configurations to deploy nightscout and nginx through docker compose onto an AWS EC2 instance.

Prerequisites

You need to have set up an AWS instance in EC2 and have a domain or sub domian pointing to it and install docker and docker-compose on it. You can find the instructions for that here.

You also need access to a MongoDB database. You can find instructions on how to set that up here or you can sign up to MongoDB atlas here.

You should also clone this repository onto the EC2 instance.

Installation

First you should look at the insructions found here to see what variables you need to set up. There is an example .env file in this repository that you can use as a template. You can also use the following command to generate a random password for the API_SECRET variable:

openssl rand -base64 32

Next you need to replace {YOUR_DOMAIN_HERE} in the nginx.conf file with your domain.

Once you have set up the .env file you can run the following command and follow the prompts to generate the lets encrypt certificates:

sudo docker compose run --rm  certbot certonly --webroot --webroot-path /var/www/certbot/ -d nightscout.kenanjasim.com

Then when you run the following command it will start the nightscout and nginx containers:

sudo docker compose --profile=nightscout --env-file=env up

Then you can bring them down by running:

sudo docker compose --profile=nightscout --env-file=env down

You should then be able to navigate to the domain you set up and see the nightscout site.

Renewing the certificates

You can renew the certificates by running the following command:

sudo docker compose --profile=donotstart run --rm certbot renew
