What is Dockerfile

A Dockerfile is a script that contains instructions for building a customized docker image. Each instruction in a Dockerfile creates a new layer in the image, and the final image is composed of all the layers stacked on top of each other.

It includes instructions for installing dependencies, copying files, setting environment variables, and configuring the container.

Dockerfile uses a simple, easy-to-read syntax that can be created and edited with any text editor. Once a Dockerfile has been created, it can be used to build an image using the docker build command. The resulting image can then be run as a container using the docker run command.
