How to install and use the nginx proxy + letsencrypt

To use the nginx proxy to serve mulitple instances of dockerised nginx in the same servers you need to do the following:

duplicate the configuration example

In proxy/hosts copy the file default.conf.example and rename is so it fits your endpoint. Please make sure to use the extension .conf

Edit your new file and make sure to replace the following:

URL with the url of your endpoint

PORT with the name of the nginx instance of your docker exposing port 80

Install and run this docker

cd .docker
docker-compose build
docker-compose up -d

Open port 80 and 443 in UFW

sudo ufw allow 80
sudo ufw allow 443

Make sure you can run letsencrypt.sh

sudo chmod +X letsencrypt.sh

Test the creation of the certificate

./letsencrypt.sh -d YOURDOMAINNAMEHERE -e YOUREMAILHERE -s

Create the certificate

./letsencrypt.sh -d YOURDOMAINNAMEHERE -e YOUREMAILHERE

Edit your configuration

In your configuration file in proxy/hosts you need to remove all the comments

Restart the docker

cd .docker
docker-compose down
docker-compose up -d

You are good to go, the proxy will manage the certificate, and your nginx should only expose port 80
