1 • Development
Lets say You created an Application And that's working fine in your machine
2 • Production
But in Production it doesn't work properly Developers experience it a lot
3 • That is when the Developer's famous words are spoken
Client - Your application is not working 😡
Developer - It's working on my Machine 😒
4 • The Reason could be due to:
• Dependencies
• Libraries and versions
• Framework
• OS Level features
• Microservices
That the developers machine has but not there in the production environment
5 • DOCKER
We need a standardized way to package the application with its dependencies and deploy it on any environment. Docker is a tool designed to make it easier to create, deploy, and run applications by using containers.
So it will always work the same regardless of its environment
6 • How Does Docker Work?
Docker packages an application and all its dependencies in a virtual container that can run on any Linux server.
7 • Each container runs as an isolated process in the user space and take up less space than regular VMs due to their layered architecture.
