sfneal/certbot

Certbot Docker image for managing Lets Encrypt SSL certificates. Requests & validates certificates from a validation server (configured with environment vars) that can be shared with webserver containers through Docker volumes.

Installation

Docker images can be pulled using the Docker CLI.

docker pull stephenneal/certbot:v9

Usage

Add a 'certbot' container with a certs volume that is shared with your webserver(s) to your docker-compose.yml.

certbot:
  image: stephenneal/certbot:v9
  container_name: certbot
  volumes:
    - certs:/etc/letsencrypt
  environment:
    - validation_domain=validation.example.com
    - email=user@example.com
    - staging=1 # use '1' for development environments
  depends_on:
    - webserver
  restart: "no"

When used in conjunction with stephenneal/nginx-* containers all of the domains being used by the webserver's will be written to a text file ('/etc/letsencrypt/domains.txt') that is parsed by the certbot to determine what domains to request certificates for.
