Docker file, Docker image & Docker Container | Docker Tutorial
Docker is a popular platform for building, shipping, and running applications using container technology. In this video, we will explain the concepts of Dockerfile, Docker Image, and Docker Container:
Dockerfile: A Dockerfile is a text file that contains a set of instructions for building a Docker image. These instructions specify the base image, any dependencies that need to be installed, and the commands needed to set up the environment required to run the application.
Docker Image: A Docker image is a lightweight, standalone, and executable package that includes everything needed to run an application. The image is built using the instructions specified in the Dockerfile and contains the application code, runtime environment, and all dependencies.
Docker Container: A Docker container is an instance of a Docker image that is running as a process on the host operating system. Each container is isolated from other containers and the host system, providing a secure and consistent environment for running the application.
By understanding the concepts of Dockerfile, Docker Image, and Docker Container, you can build and deploy applications easily, quickly, and consistently across different environments
