What is it, and how does it work?
Docker is a tool that packages software into containers that can run in a reliable manner in any environment.
So if you didn't understand what that means, imagine a cardboard box that contains all the parts of a software application.
This box is the container, and it contains everything the application needs to run, including libraries, configuration files, and other dependencies.
The container is then deployed to a server, and the application runs inside the container. This means that the application can run anywhere, regardless of the underlying operating system or environment.
What are the benefits of using Docker?
Deployment
Using Docker has many advantages. For starters, it makes it easier to deploy applications. You don't have to worry about compatibility issues, since the application runs in a container that is isolated from the underlying environment.
Management
It also makes it easier to manage applications. Instead of having to manage multiple versions of the same application, you can just deploy a single container. This makes it easier to keep track of the application and its dependencies.
Scalability
Finally, Docker makes it easier to scale applications. You can easily deploy multiple containers to handle increased demand, and you can also scale down when demand decreases.
