Getting Nginx to run with Let’s Encrypt in a docker-compose environment is trickier than you’d think …
The other day, I wanted to quickly launch an nginx server with Let’s Encrypt certificates. I expected the task to be easy and straightforward. Turns out: I was wrong, it took a significant amount of time and it’s quite a bit more complicated.
Of course, in the grand scheme of things, it is pretty straightforward. But there are a couple of details you need to be aware of. The goal of this guide is to help you build a docker-compose setup that runs nginx in one container and a service for obtaining and renewing HTTPS certificates in another. Whether you’re using nginx as a proxy for your web app or just for serving static files, this guide is for you.
TL;DR: The full code from this guide is available on GitHub.
