Running Containers on AWS Fargate

Create a Docker Image Repository

In this module, you’ll create a Docker container image repository in Amazon Elastic Container Registry (ECR). Amazon ECR is a fully-managed Docker container registry that makes it easy for developers to store, manage, and deploy Docker container images without worrying about managing or scaling the underlying infrastructure.

Amazon ECR is integrated with Amazon ECS to simplify production deployment workshop and IAM which provides resource-level control of each repository.

You’ll use this repository to store our Docker container images so that we can deploy them to AWS Fargate via Amazon ECS.

Implementation

Create a new repository in Amazon ECR called workshop. Note the Repository URI of the repository.

✅  Step-by-step Instructions (AWS Management Console)

1. Go to the AWS Management Console, click Services then select Elastic Container Service under Compute.

2. Click Repositories in the left-hand navigation.

3. Click Get started if this is your first visit to the Amazon ECR console, or Create repository if you’ve used it before.

4. Enter workshop into Repository name.

5. Note the contents of the Repository URI field.

   

6. Click Next step. Your repository has been created.

   

✅  Step-by-step Instructions (AWS CLI)

1. Switch to the tab where you have your Cloud9 environment opened.

2. Use the AWS CLI to create the repository by running aws ecr create-repository --repository-name workshop in the Cloud9 terminal:

   aws ecr create-repository --repository-name workshop

   Copy to Clipboard

   Admin:~/environment $ aws ecr create-repository --repository-name workshop

   {
       "repository": {
           "registryId": "123456789012",
           "repositoryName": "workshop",
           "repositoryArn": "arn:aws:ecr:us-east-1:123456789012:repository/workshop",
           "createdAt": 1515180775.0,
           "repositoryUri": "123456789012.dkr.ecr.us-east-1.amazonaws.com/workshop"
       }
   }

3. Note the contents of the repositoryUri field.

⭐ Recap

🔑  Amazon ECR is a fully managed Docker image registry that makes it easy to store built Docker images in the cloud without worrying about managing or scaling the underlying infrastructure.

🛠️  You created a Docker image repository in Amazon ECR. The repository has a URI which you’ve noted for use in the coming modules.

Next

✅  Proceed to the next module, Build and Push a Docker Image, wherein you’ll clone a sample application from GitHub, build a Docker container from it, and push that into your new repository in Amazon ECR.
