SSL on Docker with Nginx and Certbot

Basic boilerplate to create SSL certificates from letsencrypt for your host with auto-renewal combining certbot and nginx in a docker-compose environment.

This repo is intended to be used with projects which use of docker-compose and nginx.

Also, the following steps are expected to be executed in a machine with a public IP and a DNS mapping a domain name to it.

Clone this repository into your repository's root

1. From repository's root

   git submodule add [email protected]:jon-alamo/ssl-on-docker.git
   git add .gitmodules
   git commit -m "Added ssl-on-docker repostiory as submodule" .gitmodules
   git push
   

2. Create env vars If not exits, create .env file on the ssl-on-docker repository's directory and add the following variables:

   DOMAIN_ARGS=-d sub1.yourdomain.com -d sub2.yourdomain.com -d yourdomain.com
   STAGING_ARG=--staging (or leave blank)
   EMAIL_ARG=<your email>
   NETWORK_NAME=<main project network name>
   

3. Create certificates for the first time

   docker-compose -f ssl-on-docker/docker-compose.init.yml up
   

4. Prepare nginx configuration Create nginx configuration file called app.conf under nginx directory in your main project's root.

5. Ensure that the following lines are present in the nginx configuration file:

   ssl_certificate /etc/letsencrypt/live/<yourdomain.com>/fullchain.pem;
   ssl_certificate_key /etc/letsencrypt/live/<yourdomain.com>/privkey.pem;
   

Run your app

Run your project's docker-compose as usually.
