Thanks for the contribution @qari. I want to see if there is a way to apply your changes without diverging too much from the blog post.

@mikechernev It should be good if you don't worry about changes (improvements) in the repo to keep it in sync with the blog post, just edit your blog post to use a link to a branch or commit, and then allow yourself to merge good PRs and ideas, so this can become a good starting point for developers, even if docker (and its "techniques") evolve

[mikechernev]

Very good point... I will create those branches and merge this :)
