if you are brave to install bundle in your machine:

• bundle exec jekyll serve --drafts
• bundle exec jekyll help
• bundle exec jekyll draft "my new post"
• bundle exec jekyll publish _drafts/my-new-post.md

if you have docker you can run all those commands like this: docker run --rm --volume="$PWD:/srv/jekyll" -it jekyll/jekyll bundle update

or if you want to serve the site locally just run docker-compose up

for more commands using docker see https://github.com/envygeeks/jekyll-docker/blob/master/README.md
