If you are aware of how DevOps works, then you are already familiar with a variety of tools that DevOps engineers and professionals use. Some of them are used on a regular basis, such as continuous integration and continuous delivery, which is more like a methodology and technique and less like a tool. Then there are those that run these methodologies and so-called techniques such as Docker. Docker itself is a containerization program that can help you continue upgrading a particular software or tool by coming up with a piece or fraction of it and packing it into a container.
These containers provide great help in terms of accelerating the process of development and delivery. Professionals also won’t have to do everything from scratch while continually releasing newer updates and patching fixes. What’s done will remain in the main source code repository, and the continued development can be taken on from there. Docker is not only an immersive object to deal with but also greatly in-demand where DevOps exists. That is why if you want to become a professional in the field, you must have Docker training. For that reason, here is a list of the best certifications and courses that you can undertake in order to learn the core fundamentals of Docker.
