Dockerfile

Docker is a tool that makes it easy to run applications in containers. Containers are like small packages that hold everything an application needs to run. To create these containers, developers use something called a Dockerfile.

A Dockerfile is like a set of instructions for making a container. It tells Docker what base image to use, what commands to run, and what files to include. For example, if you were making a container for a website, the Dockerfile might tell Docker to use an official web server image, copy the files for your website into the container, and start the web server when the container starts

first, clone the application in your aws server

Write dockerfile as below:

Provide permission to docker user using the below command

• sudo usermod -aG docker $USER

Build the docker image:

Run the docker image and create the container:

Open the security group in AWS with edit inbound rules:

• Verify that the application is working as expected by accessing it in a web browser

• Push the image to a public or private repository (e.g. Docker Hub )

  login to docker hub create account >> on server use command docker login

  

    docker login
    docker ps
    docker tag django-todo-cicd_django_todo_app madhurip16/django-todo-app:latest
  

    docker images
    docker image push <image-name>
