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**
1⃣ Log in to your **AWS Management Console**
2⃣ Go to **Elastic Container Registry (ECR)**
3⃣ Click **Create Repository**
4⃣ Choose **Private or Public** (Private is recommended)
5⃣ 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.
