Go to AWS management console, then go to Amazon ECR service

In the Amazon ECR console, select “Repositories” from the left navigation pane.

Click the “Create repository” button.

Enter a unique name for your repository in the “Repository name” field.

Click the “Create repository” button.

Repository is created

Step 5: Build Docker Image Locally

Using your machine, navigate to the directory containing your Dockerfile

Build your Docker image.

docker image is created

Step 6: Push Docker Image to ECR

1. Go back to the AWS Management Console.

2. In the Amazon ECR console, select your repository from the list.

3. In the repository details, click the “View push commands” button.

4. Follow the provided instructions to authenticate Docker with your ECR registry and push your Docker image.

1. Retrieve an authentication token and authenticate your Docker client to your registry. Use the AWS CLI:

aws ecr get-login-password --region ap-south-1 | docker login --username AWS --password-stdin 211125656815.dkr.ecr.ap-south-1.amazonaws.com

2. Build your Docker image using the docker build command. You can skip this step if your image is already built.

3. After the build completes, tag your image so you can push the image to this repository:

docker tag demo-app:latest 211125656815.dkr.ecr.ap-south-1.amazonaws.com/demo-app:latest

4. Run the following command to push this image to your newly created AWS repository:

docker push 211125656815.dkr.ecr.ap-south-1.amazonaws.com/demo-app:latest

Step 7: Verify Image in ECR Console

Once the image is pushed, go back to the Amazon ECR console. Select your repository.

Check the “Images” tab to verify that your Docker image has been successfully pushed.
