Docker - Roadmap by Bookmarks

Docker - Roadmap by Bookmarks
"Hey mate, I just started Docker. It's kind of awesome actually!"

Coincidence or not, but I had for this post some friends starting their Docker journey to inspire me, and what a great and easy time to start a container journey with the ocean of tutorials and solutions now available about Docker !

BREAKING NEW: Mirantis, a specialist of OpenStack, Kubernetes and Cloud Solutions, bought Docker Enterprise. Which changes nothing of the purpose of this post for the moment since we were gonna work mostly with the open-source edition.

As I told it, there are already plenty of blogs and explanations about Docker available. So instead of writing another one to explain what has already been explained, I propose to find on this page my little selection of links that I would recommend you for your sailing.

Suggested requirement before start

Seems Docker and containers could be a difficult subject for neophytes, I suggest you to have at least some knowledge about:

  • Virtual Machine / virtualisation to understand the difference with a container
  • Some basic level in programming language, to understand the purpose of Docker
  • A Docker environment to practice. Check here to install it
  • Some basic concept about Devops, since Docker is fully influenced by that philosophy

Roadmap

The following links come mainly from my porter.io subscription. If you don't know this tool, I suggest it to you. Pretty cool to receive your daily dose of technology news matching your Github stars.

The Roadmap would be split into different levels of progression, each of them with a set of possible questions you may ask yourself about Docker. Click on them to visit the associated blog post.

Conclusion

As you have seen, there are many things to understand around Docker before using it to its full potential. For now, if you've managed to go through everything, congratulations!

You should have understood that Docker is more a tool for development stage and local test than production environment. Other tools like Kubernetes would be in that case more efficient and scalable.

However, despite his controversial situation, Docker remains an excellent tool to begin and learn how to manipulate containers. The next step is to learn how to develop efficient microservices!
