Create a Private Docker REPO on AWS ECR

Greetings, In this blog post I will demonstrate how to Create a private docker repository on amazon elastic container registry (ECR).

Creating a private Docker repository on Amazon Elastic Container Registry (ECR) allows you to securely store and manage your Docker images.
In this blog post, we will cover the steps to create a private Docker repository on Amazon ECR and how to push and pull images to and from the repository created.

Requirements for this tutorial

1. An AWS account: You will need to have an AWS account in order to access the ECR service.

2. IAM user with appropriate permissions: You will need to have an IAM user that has the necessary permissions to create and manage ECR repositories and images. This will typically include permissions such as ecr:CreateRepository, ecr:ListImages, ecr:DescribeRepositories, ecr:PutImage, and ecr:GetAuthorizationToken.

3. Docker installed on your machine: You will need to have Docker installed on your machine in order to interact with the ECR repository using the Docker command-line interface.

4. AWS CLI installed on your machine: You will need to have AWS CLI installed on your machine to perform the authentication step.

5. It is also good to have some knowledge of the basics of Docker and AWS, as well as experience working with the command-line interface to be able to follow through with this tutorial.

That being said lets deep dive into the tutorial which is described in several steps.

Step 1: Create an Amazon ECR Repository

Log in to the AWS Management Console and navigate to ECR.
Click on the "Create repository" button.
Give your repository a name and click on the "Create repository" button.
Step 2: Authenticate Docker to Your AWS Account

Run the following command in your terminal to authenticate Docker to your AWS account:

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: Tag Your Docker Image

Run the following command to tag your Docker image with the repository name and the tag you want to use. Replace the placeholders with your own values:

docker tag <image-name> <your-account-id>.dkr.ecr.<your-region>.amazonaws.com/<repository-name>:<tag>

Step 4: Push the Image to the Repository

Run the following command to push the image to the repository:

docker push <your-account-id>.dkr.ecr.<your-region>.amazonaws.com/<repository-name>:<tag>

Step 5: Pulling Images from the Repository

Run the following command to pull an image from the repository:

docker pull <your-account-id>.dkr.ecr.<your-region>.amazonaws.com/<repository-name>:<tag>

Once you've followed these steps, your private Docker repository on Amazon ECR is set up and ready to use. You can push and pull images to and from the repository as needed. Keep in mind that only users with the appropriate permissions will be able to access and manage the images in your private repository.

In addition, you can use AWS CLI or SDKs to automate the process of creating and managing repositories, images, and permissions.

In this way, you can easily create a private Docker repository on Amazon ECR and manage your Docker images with more security and flexibility.
