In this video on what is Dockerfile we will study about Dockerfile which is a critical element in Docker that defines the instructions to build a Docker image. A Dockerfile is essentially a script containing a set of commands that specify how to assemble an image, including setting up the base environment, installing dependencies, and configuring the application. By using Dockerfiles, you can automate the image creation process, ensuring that your applications are consistent and easily deployable across different environments.To help you understand, we'll go through a practical example where we create a simple application, write a Dockerfile for it, and then build and run the Docker container. By the end of this tutorial, you'll have a solid grasp of Dockerfiles and how they simplify building and deploying applications.
