Docker: When you spin the jekyll on the docker,

Docker recommends taking the time to learn. Once you're used to dockers, it's easier to build a development and testing environment.

First, you can receive the jekyll through the following route.

https://hub.docker.com/r/jekyll/jekyll

You can create a container with the command below.

The --volume option is called a data volume, which is the path of the host.

This means that the host directory is accessible from the container. Data disappears when the container is shut down, so data such as the source code that changes using the data volume is managed separately.

export JEKYLL_VERSION=3.8
docker run --rm \
  --volume="$PWD:/srv/jekyll" \
  -it jekyll/jekyll:$JEKYLL_VERSION \
  jekyll build
