Learning Docker is as easy as enrolling in an online course from our top recommendations. However, many people fail to realize the importance of such a profession and how it is relevant in the world today. Moreover, there are notable caveats to be had before starting your journey as a Docker container expert.
Now that you are showing a keen interest to practice docker, you might be wondering how to start learning docker from scratch. Docker is essentially the precise execution of variable software programs to become self-sufficient containers. More importantly, these digital canisters act as cloud-based algorithms that can stay secure for indefinite periods.
If your ultimate goal is to become a DevOps Engineer then learning docker from scratch really helps you achieve your goal.
These self-contained data resources can operate anywhere where a reliable computing system exists. As a result, learning the process, techniques, and innovation behind this technology holds incredible value in today’s digital world.
How to Start Learning Docker
Docker specialists, like other professions, have specific requirements before receiving full access to commercial and industrial workloads. They need to attain Docker certification before even getting a chance at an interview within a reputable company. Today, organizations transfer massive amounts of data each day. As a result, they need someone who underwent the training and education to pass certification.
The Docker certification launched in 2017, and since then, companies have started requiring their Docker associates to have it in their resumes. In this article, we will proceed with the notion that you aim to achieve certification above anything else.
Before you become a certified associate, various approaches can help ensure a higher passing rate. For our recommendation, the focus lies in the realm of online learning. More importantly, this approach has produced many successful Docker specialists in the industry today.
Prerequisites to Learn Docker
To start learning Docker, you need to have ample knowledge or familiarity with the platform and systems behind it. Mainstream topics such as web services, virtual machines, Java, and various operating systems should be second nature to you. However, we will feature courses that cater to a broad spectrum of individuals, ranging from beginner to expert level.
There is no universal prerequisite, but some of the highly-rated courses we’ve reviewed suggest having some form of background knowledge. If you have some skill set on the command line or knowledge of Github, it would be of great help.
Indeed, like with any profession, staying one step ahead of the competition will give you an edge when candidate selection finally comes. More importantly, stockpiling information before starting a course should help you understand the topics better and absorb lessons more fluidly.
For those who have lots of time to spare, we suggest going through the entire course introduction twice or thrice. For obvious reasons, mastery of fundamental topics should be your priority. In this way, you can seamlessly connect lessons without having to go back to a previous discussion.
