NGINX-Certbot-Docker

Boilerplate code for setting up Nginx + Certbot (LetsEncrypt) with auto-renewal using docker-compose. This is really for testing, playing and understanding (I hope).

Why?

I found many repos and tutorials online for setting up LetsEncrypt SSL certificates for Nginx containers, but found them hard to follow and many wrapped important bits in automated scripts.

Requirements

dependency	commands
docker	commands for Debian / Ubuntu
docker-compose	commands for Debian / Ubuntu

Set up

Clone and enter the repo:

git clone https://github.com/dancasey-ie/nginx-certbot-docker
cd nginx-certbot-docker

Set your domain and email variables for generating your LetsEncrypt certificate

export DOMAIN=<your_hosted_domain>
export EMAIL=<your_email>

Configure your DNS to direct both "<your_hosted_domain>" and "www.<your_hosted_domain>" to your server.

If you just want to run using non-secured http:

docker-compose -f compose-http.yml up # make up_http

If you want to run using https you first must run without https and ask Certbot for a certifcate:

docker-compose -f compose-init-ssl.yml up # make init_ssl

Exit with CTRL+C. Then run:

docker-compose -f compose-https.yml up # make up
