This guide will cover the fundamentals of Git. You will learn why version control is necessary and how version control systems work. This information will help you to master practical work with Git successfully.
Software development is a challenging process that tends to become much more complex as the number of participants increases. More people in the team create more communication and require more synchronization (sharing knowledge of system parts and processes, keeping track of the business and its requirements). The cost of error increases, and the system can no longer fit in just one head, while a change on one side triggers other changes.
There are no programs without errors. Their number can be reduced with the great help of a type system, linters, tests, or even a whole department of testers, but it’s impossible to remove them completely. This is the reality we must face; the best thing we can do is learning how to track these errors and fix them as soon as possible.

Docker is a program that allows the operating system to run processes in an isolated environment based on specially created images. And, while the technologies underlying Docker existed earlier, it was Docker that changed the way we now build project infrastructure, assemble and launch services.
