# Boilerplate for nginx with Let’s Encrypt on docker-compose

|

set up nginx and Let’s Encrypt with Docker](https://medium.com/@pentacent/nginx-and-lets-encrypt-with-docker-in-less-than-5-minutes-b4b8a60d3a71).

`init-letsencrypt.sh` fetches and ensures the renewal of a Let’s
|
||||
Encrypt certificate for one or multiple domains in a docker-compose
|
||||
setup with nginx.
|
||||
This is useful when you need to set up nginx as a reverse proxy for an
|
||||
application.
