Want to deploy your **Flask app** using **AWS Elastic Container Registry (ECR)**? 🚀 In this tutorial, I’ll walk you through the **entire process** of building a Docker image, pushing it to AWS ECR, and running it on your system or an AWS service. By the end of this video, you’ll know how to **PUSH, PULL, and RUN** a **Flask app container** with AWS ECR and manage your containerized applications like a pro! 💻 — ## **🔹 What You’ll Learn in This Video:** ✅ How to **set up AWS ECR** for container image storage ✅ How to **build and tag a Docker image** for a Flask app ✅ How to **push the Docker image** to AWS ECR ✅ How to **pull the image** from AWS ECR ✅ How to **run the container** locally using Docker — ## **🔹 Prerequisites** ✔️ **AWS Account** (Sign up at [aws.amazon.com](https://aws.amazon.com/)) ✔️ **Docker Installed** ([Download Docker](https://www.docker.com/get-started)) ✔️ **AWS CLI Installed & Configured** ([AWS CLI Guide](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html)) ✔️ Basic knowledge of **Flask and Docker** — ## **🔹 Step 1: Create an AWS ECR Repository** 1️⃣ Log in to your **AWS Management Console** 2️⃣ Go to **Elastic Container Registry (ECR)** 3️⃣ Click **Create Repository** 4️⃣ Choose **Private or Public** (Private is recommended) 5️⃣ Copy the **ECR repository URL** — ## **🔹 Step 2: Authenticate Docker with AWS ECR** Before pushing a Docker image, you need to log in to AWS ECR: “`bash
aws ecr get-login-password –region your-region | docker login –username AWS –password-stdin your-account-id.dkr.ecr.your-region.amazonaws.com
“` — ## **🔹 Step 3: Build & Tag Your Flask App Docker Image** First, create a **Dockerfile** for your Flask app: “`dockerfile
# Use official Python image
FROM python:3.9 # Set working directory
WORKDIR /app # Copy application files
COPY . . # Install dependencies
RUN pip install -r requirements.txt # Expose the Flask app port
EXPOSE 5000 # Run the Flask app
CMD ["python", "app.py"]
“` Now, build and tag the Docker image: “`bash
docker build -t flask-app .
docker tag flask-app:latest your-account-id.dkr.ecr.your-region.amazonaws.com/flask-app:latest
“` — ## **🔹 Step 4: Push the Docker Image to AWS ECR** Now, push the tagged image to AWS ECR: “`bash
docker push your-account-id.dkr.ecr.your-region.amazonaws.com/flask-app:latest
“` — ## **🔹 Step 5: Pull and Run the Docker Image from AWS ECR** To **pull** the image from AWS ECR: “`bash
docker pull your-account-id.dkr.ecr.your-region.amazonaws.com/flask-app:latest
“` To **run the Flask app container locally**: “`bash
docker run -p 5000:5000 your-account-id.dkr.ecr.your-region.amazonaws.com/flask-app:latest
“` Your Flask app should now be accessible at: 👉 **http://localhost:5000** — ## **🔹 Step 6: Deploy Your Flask App to AWS Services (Optional)** After pushing your Docker image to AWS ECR, you can use it with: ✔️ **AWS Fargate** (Serverless container hosting) ✔️ **Amazon ECS** (Elastic Container Service) ✔️ **Amazon EKS** (Kubernetes Service) — ## **🔹 FAQs About AWS ECR & Docker** 🔹 **What is AWS ECR?** AWS **Elastic Container Registry (ECR)** is a managed container registry to store, manage, and deploy Docker container images. 🔹 **Why use AWS ECR instead of Docker Hub?** AWS ECR offers **private repositories**, **seamless AWS integration**, and **IAM-based security controls**. 🔹 **Can I automate the push process?** Yes! You can use **GitHub Actions, AWS CodePipeline, or Jenkins** for CI/CD automation. — ## **🔹 Who Is This Tutorial For?** ✅ Developers **deploying Flask apps with Docker** ✅ DevOps engineers working with **AWS ECR & ECS** ✅ Anyone **new to AWS container management** — ## **🔹 More AWS & Docker Tutorials:** 📌 **How to Deploy a Flask App with AWS EC2 & Nginx** → [Watch Now] 📌 **How to Build & Run a Flask Docker Container** → [Watch Now] 📌 **How to Deploy a Django App with AWS Elastic Beanstalk** → [Watch Now] — ## **👍 Like, Share & Subscribe!** If this tutorial helped you, please **LIKE, SHARE, and SUBSCRIBE** for more **AWS, Docker, and DevOps tutorials**! 🚀 💬 Have questions?
