Letsencrypt Docker

Simple tutorial that show how to deploy services in a practical way using docker, nginx and letsencrypt.

How to run

1. Replace example.org with your domain name and the server ip/port

# data/nginx/app.conf
upstream whoami {
    server 10.0.0.10:8000;
}

server_name example.org;

ssl_certificate /etc/letsencrypt/live/example.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.org/privkey.pem;

# init-letsencryptinit-letsencrypt
domains=(example.org)

2. Create a dummy certificate

chmod +x init-letsencrypt.sh
sudo ./init-letsencrypt.sh

3. Automatic Certificate Renewal To activate auto renew uncoment the following lines on docker-compose.yml file:

Nginx service

# command: "/bin/sh -c 'while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g \"daemon off;\"'"

Certbot service

# entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

4. Everything is in place now. The initial certificates have been obtained and our containers are ready to launch. Simply run docker-compose up and enjoy your HTTPS-secured website or app.
