1.Create EC2 Instance (if not done)

• • In my previous blog, I have already covered the steps for creating an EC2 instance. Please follow the provided instructions for a smooth and successful implementation.

    https://hashnode.com/post/clnumbs4u000208ifg51u1xm4

    Once an EC2 instance is successfully created in AWS following the above

    steps.

2.Connect to Instance Using SSH

Run

ssh -i instance.pem ubuntu@<IP_ADDRESS>

3.Update Package ,and Install Docker

$sudo apt update

$sudo apt install docker.io

4.Create a new directory ,and check docker process status

$ mkdir docker_project

$ docker ps

5.Add user into docker group

• Check user group ,run below cmmand

  $ sudo cat /etc/group

  

• Add user into docker group,and check user group

  $ sudo usermod -aG docker $USER

  

6.Restart docker or Reboot

$sudo systemctl restart docker

Still if you are facing permission denied issue ,then Reboot the instance

$sudo reboot

Now you need to check docker process status,and permission denied issue is resolved.

$docker ps

7.Pull mysql docker image from Docker Hub

$docker pull mysql:latest

8.Check Downloaded mysql image

$docker image ls

9.Run Mysql Docker image

$docker run mysql:latest

10.Set Environment Variable to Create Container

$docker run -d -e MYSQL_ROOT_PASSWORD=test@123 mysql:latest

11.Check Container Status for mysql

$docker ps

Now your mysql container up and running

12.Execute mysql container ,and Access Mysql container

$docker exec -it 228b5561becb sh

Access mysql database

sh-4.4#mysql -u root -p

Enter Password:test@123

mysql>show databases

13.Exit from mysql ,and shell

mysql>exist

sh-4.4#exit

Building a Flask To-Do List App with Docker and Deploying on AWS 🚀

Introduction

In this guide, I'll take you through the exciting journey of creating a small Flask app project — a "To-Do List" application. The best part? We'll containerize it using Docker and deploy it on AWS. Let's dive in! 📝

Setting Up the Project Structure 📁

📁 Create a folder for your project and set up the following structure:

1.Create a Project Folder:

• Execute the following command to create a new folder for your project:

$mkdir flask-app

2.Main Application Script (app.py):

• Create the app.py file in the flask-app folder and add the necessary content. This script will be the heart of our Flask application.

3.HTML Template (templates/index.html):

• Create the templates folder and within it, create the index.html file. This HTML template will be the main page template for our app.

$mkdir templates

4.CSS Stylesheet (static/style.css):

• Similarly, create the static folder and within it, create the style.css file. This CSS stylesheet will provide styles for our application.

Dockerizing the Flask App 🐳

Create Dockerfile:

• Create a Dockerfile in the flask-app folder with the required configurations. This file will guide Docker in building the container for our app.

Requirements.txt:

• Create a requirements.txt file with the necessary Python dependencies for your Flask app.

Building and Running the Docker Container 🏗️

1.Build the Docker Container:

• Open a terminal, navigate to the project folder (flask-app), and run the following command to build the Docker image:

$docker build -t flask-app .

2.Run the Docker Container:

• Start the Docker container by running:

$docker run -p 5000:5000 flask-app

• Adjusting Inbound Rules on AWS 🌐

  Adjust EC2 Security Group:

  • Don't forget to adjust the inbound rules in your EC2's security group to allow traffic on port 5000, ensuring that our app can be accessed.

• Congratulations! 🎉

  1.Access Your To-Do List App on AWS:

  • Copy your instance's public IP and access the app using that IP and port 5000.

Copy your instance public ip ,and port 5000

Congratulations! You've successfully deployed your To-Do List application using Docker on AWS. This step-by-step guide ensures a smooth journey from project setup to deployment. Happy coding! 🚀🔧
