How one can Deploy Containerized Apps on AWS Using ECR and Docker — SitePoint

Apr 3, 2023

Are you trying to deploy your containerized applications on the cloud? Amazon Web Services (AWS) provides a sturdy and scalable platform that may allow you to do exactly that. On this tutorial, we’ll guide you thru the means of deploying your containerized applications on AWS using Amazon Elastic Container Service (ECS), Elastic Container Registry (ECR), and Docker.

Step 1: Create an AWS Account

To make use of AWS, it is advisable create an AWS account first. Go to the AWS website and click on Sign In to the Console to create a recent account. You’ll must fill in personal information, billing information, and payment information.

Step 2: Create an Elastic Container Registry (ECR)

To store your Docker images, create an ECR repository:

  • Register to the AWS Management Console.
  • Open the Amazon ECS console.
  • Select Repositories.
  • Select Create repository.
  • Give the repository a reputation and click on Create repository.

Step 3: Push Docker Images to ECR

Now it is advisable push your Docker images to the ECR repository you simply created:

  • Install the AWS CLI in your computer.

  • Within the AWS Management Console, go to Users and create a recent user with the obligatory permissions to push images to your ECR repository.

  • Open a command prompt and run the next commands:

    aws configure
    aws ecr get-login –no-include-email –region
    ($(aws configure get region) on Linux/macOS)

    This command will print a Docker login command you could use to authenticate your Docker client to your ECR registry.

  • Run the Docker login command that was printed within the previous step.

  • Tag your Docker image with the ECR repository URI.

  • Push your Docker image to the ECR repository using the next command:

    docker push /:

Step 4: Create an ECS Task Definition

To deploy your Docker containers on AWS, it is advisable create an Amazon ECS task definition:

  • Open the Amazon ECS console.
  • Select Task Definitions from the navigation pane.
  • Select Create recent Task Definition.
  • Select EC2 Launch Type.
  • Give your task definition a reputation and supply the Docker image URI.
  • Add a port mapping if obligatory.
  • Select Create.

Step 5: Create an ECS Cluster

An Amazon ECS cluster is a logical grouping of Amazon EC2 instances you could launch tasks on:

  • Open the Amazon ECS console.
  • Select Clusters from the navigation pane.
  • Select Create Cluster.
  • Select EC2 Linux + Networking.
  • Give the cluster a reputation and choose a VPC and subnets.
  • Select Create.

Step 6: Launch Container Instances in your Cluster

To launch container instances in your ECS cluster, create an Amazon EC2 instance with the obligatory IAM permissions:

  • Within the Amazon EC2 console, select Launch Instances.

  • Select an Amazon Machine Image (AMI) that supports Docker.

  • Launch the instance in the identical VPC and subnets as your ECS cluster.

  • Add the IAM role to your instance’s IAM profile.

  • SSH into the instance.

  • Use the next command to affix the instance to the ECS cluster:

    sudo yum install -y aws-cli
    aws configure set region
    aws ecs create-cluster –cluster-name [–region ]

Step 7: Deploy your Containers on the Cluster

To run your container in your ECS cluster, it is advisable create a service that specifies the variety of tasks to run and the duty definition to make use of:

  • Open the Amazon ECS console.
  • Select the cluster you created earlier.
  • Select Services from the navigation pane.
  • Select Create.
  • Provide a reputation for the service.
  • Select the duty definition you created earlier.
  • Select the variety of tasks to run.
  • Select the launch type for the service.
  • Select Create Service.

That’s it! You may have now successfully deployed containerized applications on AWS using ECS.

Common Questions

What security measures ought to be taken while working with ECR?

When working with Amazon ECR, there are several vital security considerations it is advisable have in mind.

Firstly, all access to your repository should be secured via authentication and authorization mechanisms like AWS Identity and Access Management (IAM). Moreover, be sure that any sensitive information stored within the registry is encrypted each at rest and through transport.

You furthermore mght wish to use secure protocols for communication between the client and server, akin to TLS 1.2 or higher.

Finally, repeatedly audit your configuration settings and update them when obligatory. By taking these steps, you’ll significantly reduce the danger of unauthorized access to your container repositories.

How do I monitor performance of my Docker containers once they’ve been deployed?

To observe the performance of your Docker containers after deployment, you should use tools akin to Docker Inspect, which provides detailed details about running containers including CPU usage, memory usage, network traffic, and so forth.

Alternatively, you would deploy monitoring agents akin to Prometheus or Grafana to gather real-time metrics out of your containers.

As well as, most cloud providers provide their very own set of monitoring tools to assist track resource utilization and performance of your applications.

How do I debug errors occurring throughout the construct means of my Docker image?

To debug errors occurring throughout the construct means of your Docker image, you should use the docker construct –debug flag to enable debugging logs and trace the precise steps leading as much as the error.

Chances are you’ll also want to ascertain out this beneficial article on constructing Docker images. Moreover, when you’re using Kubernetes for managing your containers, you possibly can leverage its built-in logging capabilities or use third-party solutions akin to Elasticsearch Logs to achieve more insights into what’s happening in your cluster.

Finally, make certain to review the official documentation from Docker to find out about other ways to diagnose problems when constructing Docker images.
