Automatic Dockerized HTTPS with Let's Encrypt
Full Description

certbot

Dockerized certbot.

Obtaining certificates

The container will run certbot against all the domains provided with the environment variable domains.

If -e distinct=true is passed, certbot will be run separately for every listed domain.

docker volume create --name nginx-certs

# docker stop nginx

docker run \
  -v nginx-certs:/etc/letsencrypt \
  -e http_proxy=$http_proxy \
  -e domains="example.com,example.org" \
  -e email="me@example.com" \
  -p 80:80 \
  -p 443:443 \
  --rm pierreprinetti/certbot:latest

# docker start nginx

Renewing certificates

You can put in crontab a call to a script shaped like this one.

With dockerized nginx

Spin your favorite reverse proxy with something like:

docker run \
  --name some-nginx \
  -v nginx-certs:/etc/nginx/certs:ro \
  -p 80:80 \
  -p 443:443 \
  --restart unless-stopped \
  -d nginx:mainline-alpine

Example configuration for example.com in your dockerized nginx:

server {
  listen      443 http2;
  listen      [::]:443 http2;
  server_name example.com;

  ssl on;
  ssl_certificate     /etc/nginx/certs/live/example.com/fullchain.pem;
  ssl_certificate_key /etc/nginx/certs/live/example.com/privkey.pem;
