Dockerization, also known as “containerization,” refers to the process of packaging an application and its dependencies into a standardized container called a “Docker container.” Docker is an open-source platform that provides a lightweight and isolated environment for running applications.

1. Docker Installation

2. Verify that the Docker Engine installation is successful by running the hello-world image.

   sudo docker run hello-world

3. Containerizing app

   docker build -t package-name .

4. Running the image

   sudo docker run -it -p 8000:8000 package-name

   It will map 8000 port of container image to 8000 port of my machine

5. On AWS ERC we will create repo
