Containers have become the de-facto way to develop applications nowadays. They provide a standard way to package all the dependencies that your application needs. But how do you deploy a containerized application to the cloud? The cloud offers scalability, elasticity, and a "pay for what you use" model that is very desirable in modern applications. Let us imagine that you have developed your application and packaged it in a Docker container. This application can be your website, some software that you develop for your company, or anything really. This point is where most basic container and Docker tutorials end. But you want to deploy your application somewhere so others can use it. Now you will have to start learning about Kubernetes and all the complex orchestration systems. They seem so complicated for just deploying a simple application. In this complete tutorial, we will introduce you to Amazon Lightsail - a cloud service you can use to deploy your containers in a simple way without any complex orchestration system. This step by step guide will show you exactly how to deploy a container application to AWS using Lightsail. Whether you are a beginner or experienced developer, this beginner guide will show you exactly how simple cloud container deployment can be.
What is AWS?
AWS stands for Amazon Web Services and is the most widely-adopted cloud platform. It has lots of different services that help you develop and host your applications.
Using the cloud for your applications has many benefits over using your own on-premise servers. For example, it helps you lower the costs of your application, become more agile, and innovate faster.
Lower Costs
Pay only for what you use. No upfront hardware investment or maintenance costs for on-premise servers.
More Agility
Deploy resources in minutes instead of weeks. Scale up or down based on actual demand instantly.
Faster Innovation
Access to hundreds of services like databases, AI, analytics, and more without building them yourself.
Global Reach
Deploy your application close to users worldwide with multiple AWS regions and edge locations.
What is Amazon Lightsail?
Amazon Lightsail is part of AWS cloud-based offerings. It is a service that provides everything you need to deploy applications and websites to the cloud in a simple and cost effective way.
Even the pricing is made simpler - you know every month exactly what you are paying. Amazon Lightsail is an ideal way to deploy simple applications and websites and get started with AWS.
Lightsail is powered under the hood by AWS services such as virtual machines (Amazon EC2), relational databases (Amazon RDS), and other services. It offers the same level of scalability, reliability and security that you expect from any other AWS service.
At the end of 2020, Lightsail added support for deploying containers to the cloud. To do this, all you need is to provide a Docker image for your containers and Lightsail will automatically deploy it for you.
Lightsail provides an HTTPS endpoint that is ready to serve your application. It also takes care of load balancing and orchestrating the application.
No Kubernetes Required
You do not need to know Kubernetes or any complex orchestration system to manage container workloads with Lightsail. Just provide a Docker image and Lightsail handles the rest - deployment, load balancing, and HTTPS endpoints automatically.
How to Deploy an Application with Lightsail
Let us see how Lightsail works by deploying a simple NodeJS application packaged as a container image. This image is the one that Docker Desktop provides for learning their platform.
We will start this demo where most tutorials end - when your application image is hosted in Docker Hub.
Step 1: Setup Your AWS Account
The first step in this tutorial is to get an AWS account. In this AWS account you will be deploying your containers.
If you are just creating your account, the free tier should be enough for this project. The free tier will give you access to a lot of AWS services for free for the first 12 months. And you will get one month of Amazon Lightsail for free.
Keep in mind that having an AWS account is free if you do not use any services. You will not be charged for creating the account, and if you do not use the account, nothing will be charged.
Create AWS Account
Go to portal.aws.amazon.com/billing/signup and follow the registration steps. You will need a valid email address, phone number, and credit card for verification.
Log Into AWS Console
Once your account is created, log into the AWS Management Console. Search for "Lightsail" in the services search bar and navigate to the Lightsail dashboard.
Step 2: Create Your Container Service
By now you should have an AWS account and your application in Docker Hub. Log into your AWS account and go to Amazon Lightsail.
Amazon Lightsail interface is quite different from the regular AWS interface. You can see that this interface has many tabs available. The one we are interested in is Containers. But in a similar way you can create virtual instances, databases, and other cloud components using Lightsail.
Now we can create a container service, and that will take us to a form where we need to make some simple decisions.
Choose Deployment Region
The first decision is in which region you want to deploy your container image. Amazon Lightsail is available in multiple regions worldwide, so you can pick the one that is best for your application and closest to your users.
Select Power and Scale
Choose how much power to give to the machine running your containerized application. Decide on the size of the machine and how many instances you need. You can see the cost per machine, memory, and CPU each provides. After selecting the scale, you can see exactly how much this service will cost.
Configure Container Deployment
The container service can hold up to 10 container images. For each container, define a name, the image URL from Docker Hub, and how you will run and access this application. Open the appropriate port (e.g., port 3000) with the HTTP protocol so the application can be accessed via URL.
Set Up Public Endpoint
Configure a public endpoint. Choose from your deployment which container you want to make a public endpoint on the internet. After that, you are ready to start the deployment. This takes a couple of minutes.
Step 3: Access Your Deployed Application
After the deployment is complete, you can access the public endpoint for this service. At the top of the container service page, you can see the public domain. When you click that URL, you will be accessing the application you defined in the public endpoint.
Public Domain:
https://your-service.lightsail.aws.dev
Accessible from the internet. Use this URL
to access your deployed container application
from anywhere in the world.
Private Domain:
Internal container-to-container communication.
Use this when containers need to talk to each
other without making them public on the internet.
Perfect for backend services, databases, and APIs.
If you need your containers to talk to each other without making them public, use the private domain.
Managing Your Lightsail Container Service
Now you have a container application deployed in the cloud. This application is scalable. You can monitor the usage of the power you defined before in the Metrics tab. You can always modify these specs if you see that you need more or less power.
Monitor Metrics
Use the Metrics tab to monitor CPU usage, memory consumption, and network traffic. Scale up or down based on actual usage patterns.
Modify Power Specs
Adjust the container service power and scale at any time. Lightsail makes it easy to increase or decrease resources as your needs change.
Custom Domain Setup
If you need a custom domain for your application, you can get one from the Amazon Lightsail console and configure DNS records easily.
HTTPS Included
Lightsail automatically provides HTTPS endpoints for your containers. No need to configure SSL certificates manually.
Lightsail Container Service Pricing
Lightsail is very clear when it comes to cost. You can see the end cost on the screen before deployment. That includes storage, load balancing, networking, and whatever this container needs to run.
| What is Included | Details |
|---|---|
| Container Compute | CPU and memory for running your containerized application |
| Storage | Storage for container images and application data |
| Load Balancing | Automatic load balancing across container instances |
| Networking | Public and private networking, HTTPS endpoints |
| Monitoring | Built-in metrics and monitoring dashboard |
The free tier gives you one month of Amazon Lightsail for free, which is enough to test and deploy your first container application. After that, pricing is predictable and transparent - you know exactly what you will pay each month.
