In the world of software development, deploying applications can be complex. Before the era of Docker, companies often struggled with ensuring that their applications would run consistently across different environments. Virtual machines can't solve the problem of applications running in every environment. That's why Docker comes in role.
Introduction of Docker.
Docker is an open -source platform used to build, ship, and run applications inside containers.
What is a Container?
Think of a container as a digital "shipping box" for your software. When you need to transport items - like a car or a piano - you pack them securely into a box to ensure they reach their destination intact. Similarly, a container packages your source code, dependencies, and the necessary operating system components into one unit. This ensures that your website or application runs exactly the same way on a friend's computer as it does on yours.
