AWS ECS Tutorial: How to Deploy Docker Containers on Amazon ECS?

Table of Contents

What is Amazon ECS?

Amazon Elastic Container (Amazon ECS) is an AWS cloud service used for managing containers. Using Amazon ECS, developers can run their apps on the cloud without configuring an environment to run the code.
With the help of AWS accounts, deployment and management of scalable apps can be done by running them on a group of servers called clusters via API and task definitions. It can be accessed through AWS Management Consoles and SDKs.

We need Amazon ECS to solve the issues related to memory or full storage, unavailability of CPU, high utilization of CPU, and many more, for preventing our server from going down.

Here are few advantages of Amazon ECS-

• Improved Security
• Cost-efficient
• Extensible
• Easily Scalable
• Improved compatibility

This was about Amazon ECS. Now let’s have a small introduction regarding Docker.

What is Docker?

Docker allows developers to build applications based on small and lightweight containers. It shares the operating system kernel but still runs isolatedly from each other. The containers combine the app source code with OS libraries and needed dependencies for executing the code in different environments.

Feature of Docker:

• High Scalability and efficiency
• Short boot-up time
• Reusable data volume
• Isolated Application

AWS ECS Tutorial: Steps to deploy Docker containers

Now let’s move forward and get started with the deployment. Follow these steps to deploy Docker on ECS:

1) Login into AWS management console and Go to ECS service as shown below.

2) Click on Get Started Button.

3) Select the Container definition which you want to deploy and click on the Next button. (Here we’ll go with Nginx)

4) Select Application Load Balancer if you want a load balancer; otherwise, select None and click Next Button. (Here we will go without Load balancer)

5) Enter your cluster name and click on Next.

6) Review all the details of the cluster and click on the Create button.

7) Your cluster will be created. Click the View Service button to view your cluster.

8) Go to Task and click on Task ID.

9) Copy Public IP and Paste in the browser to run your Nginx application.

Note: If you have your docker image, then you can create a cluster with that.
