Have you ever wished that you could have a static website but also have the ability to easily schedule posts. Well its easier then you may think in this post we will be going over the 2 Docker containers you need to achive this
Web host
Starting out simple we need a Nginx container to host our final build of the website. We have 2 options for setting this up both are shown bellow
Docker Run
1
| sudo docker run --name nginx -v /Path/to/Site/Builds:/usr/share/nginx/html:ro --rm -it -p 8080:80 nginx

restart: unless-stopped
ports:
- 80:80
volumes:

Jekyll Worker
Building the Container
For the Worker Container we have a little more work to do. Mainly we have to build our own container that will build the site and output it to a directory for us. This can be done by running the bellow command in a directory with this Dockerfile, your Gemfile, and update.sh which handles the actual building of the site. (You may need to tweak the dockerfile slightly to ensure you are downloading your own website to build)

| docker build -t jekyll-worker:latest ./

Running the Container
Docker Run

While running everything manually is great and all lets automate it. We have a couple of options for acheiving this
