The same environment for everyone** The project runs the same way for everyone: on Windows, Linux, Mac, and on the server. This eliminates the *"it works on my machine, not on his"* problem. ### **2. Fast deployment** A container starts up in seconds. There is no need to manually install dependencies, configure services, and edit configs. ### **3. Lightness and isolation** Several applications can live on the same machine without conflicting over library and port versions. ### **4. Convenient scalability** It is easy to spin up several copies of a service, assemble microservices, or scale individual parts of the system. ### **5. Simple portability** A container can be moved to another machine, to the cloud, or to a server in one step - everything will work identically. ### **6. Environment version control** An image is a versioned template. You can roll back the environment the same way you roll back code in Git. ### **7. Fast development and tests** You can create test stands, run third-party services (databases, caches, and so on) in one click, and remove them just as easily. In short: **Docker lets you quickly deploy a predictable environment, isolate services, speed up development, and simplify deployment.**For the reviewerNote to the moderator (optional)Visible only to the moderator.
