What is Docker?– Docker is a containerization platform that packages your application and all its dependencies together in the form of a docker container to ensure that your application works seamlessly in any environment. – Docker is a containerization platform that packages your application and all its dependencies together in the form of a docker container to ensure that your application works seamlessly in any environment.
What is Docker Image?
Docker Image can be compared to a template which is used to create Docker Containers. They are the building blocks of a Docker Container. These Docker Images are created using the build command. These Read only templates are used for creating containers by using the run command. We will explore Docker commands in depth in the “Docker Commands blog”. 

What is Docker Container?

Containers are the ready applications created from Docker Images or you can say a Docker Container is a running instance of a Docker Image and they hold the entire package needed to run the application. This happens to be the ultimate utility of Docker. 

Docker Vs Virtual Machine:
  • Virtual Machines are slow and take a lot of time to boot.
  • Containers are fast and boots quickly as it uses host operating system and shares the relevant libraries.
  • Containers do not waste or block host resources unlike virtual machines.
  • Containers have isolated libraries and binaries specific to the application they are running.
  • Containers are handled by Containerization engine.
  • Docker is one of the containerization platforms which can be used to create and run containers.

I called mine php-backup7.1.2 Still inside /xampp, create a new php folder, then copy the contents of the extracted zip file into it.
