Docker & Automatic SSL = 😍

This is a simple working example how to automatically secure your NodeJS / whatever application using a NGINX reverse proxy and Certbot.

This makes use of the automatic NGINX proxy and letsencrypt-nginx-proxy-companion.

How to use

Development:

• Clone or download this repo
• Modify the .env located in .env.example to match your environment.
• Run: docker-compose up --build

Production:

• Clone or download this repo
• Setup DNS on your VPS if you haven't already
• Modify the .env located in .env.example to match your environment.
• Run: docker-compose -f docker-compose.yml -f docker-compose.production.yml up --build -d _{I would recommend this Digital Ocean droplet 😉}

DHParam Generation

By default the generation of the dhparam is disabled, the NGINX proxy will fall back to a default one. To bypass this, run the command as documented here.

There is a default dhparam-2048.pem provided by this repo, as a workaround for the lack of a working environment variable provided by the auto-NGINX proxy.

If you only want to try out this demo, you could use the key provided. Otherwise it's highly recommended to follow the instructions here and generate a new key.

Example

Todo

• Add support for all the available environment variable provided here.
• Add comments to .env file
