NGINX and HTTPs with Let’s Encrypt, Certbot, and Cron dockerization in production
Docker is a popular open source containerization platform and it frees your hands to build your applications in development and production. In this post, I'm going to walk you through how to build a production grade HTTPs secured Nginx server with Docker, Docker Compose, Let’s Encrypt(its client certbot).
