.NET Core ReactJS Deployment in AWS: A Step-by-Step Guide

.NET Core and ReactJS are two popular technologies used for building robust and scalable web applications. When it comes to deploying these applications, AWS provides a comprehensive suite of services to ensure seamless and efficient deployment. In this article, we’ll explore the step-by-step process of deploying a .NET Core ReactJS application in AWS.

Prerequisites

To follow along with this guide, you’ll need to have the following prerequisites:

• .NET Core 3.1 or later installed on your machine
• ReactJS 17.0.2 or later installed on your machine
• AWS account with necessary permissions
• AWS CLI installed on your machine
• Familiarity with .NET Core and ReactJS development

Step 1: Create a new .NET Core ReactJS project

Let’s start by creating a new .NET Core ReactJS project. Open your terminal and run the following command:

dotnet new react -o MyReactApp

This command creates a new .NET Core ReactJS project called MyReactApp.

Step 2: Install necessary dependencies

In your newly created project, navigate to the `MyReactApp` directory and run the following command:

npm install

This command installs the necessary dependencies for your ReactJS application.

Step 3: Create an AWS account and set up IAM roles

If you haven’t already, create an AWS account and set up IAM roles with necessary permissions. You’ll need to create an IAM user with the following permissions:

• AmazonEC2ContainerRegistryFullAccess
• AmazonS3FullAccess
• CloudWatchLogsFullAccess
• CloudWatchFullAccess

Take note of the access key ID and secret access key, as you’ll need them later.

Step 4: Create an ECR repository

ECR (Elastic Container Registry) is a fully-managed container registry service that makes it easy to store, manage, and deploy container images. Let’s create a new ECR repository:

aws ecr create-repository --repository-name myreactapp --region us-east-1

Replace `us-east-1` with your preferred region.

Step 5: Build and push the Docker image

In your `MyReactApp` directory, create a new file called `Dockerfile` with the following contents:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1

WORKDIR /app

COPY . .

RUN dotnet publish -c Release

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1

WORKDIR /app

COPY --from=0 /app .

ENTRYPOINT ["dotnet", "MyReactApp.dll"]

This Dockerfile uses the official .NET Core 3.1 SDK image to build and publish your application, and then uses the official .NET Core 3.1 ASP.NET image to run your application.

Now, let’s build and push the Docker image to ECR:

docker build -t myreactapp .

docker tag myreactapp:latest 123456789012.dkr.ecr.us-east-1.amazonaws.com/myreactapp:latest

docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/myreactapp:latest

Replace `123456789012` with your AWS account ID and `us-east-1` with your preferred region.

Step 6: Create an ECS cluster and task definition

ECS (Elastic Container Service) is a highly scalable and fast container management service that makes it easy to run, stop, and manage containers on a cluster. Let’s create a new ECS cluster and task definition:

aws ecs create-cluster --cluster-name myreactapp-cluster --region us-east-1

aws ecs create-task-definition --family myreactapp-task --requires-compatibilities FARGATE --network-mode awsvpc --cpu 1024 --memory 512 --region us-east-1

aws ecs register-task-definition --family myreactapp-task --requires-compatibilities FARGATE --network-mode awsvpc --cpu 1024 --memory 512 --region us-east-1 --container-definitions file://container-definitions.json

Create a new file called `container-definitions.json` with the following contents:

[
  {
    "name": "myreactapp",
    "image": "123456789012.dkr.ecr.us-east-1.amazonaws.com/myreactapp:latest",
    "cpu": 10,
    "memory": 512,
    "essential": true,
    "portMappings": [
      {
        "containerPort": 80,
        "hostPort": 80,
        "protocol": "tcp"
      }
    ]
  }
]

Replace `123456789012` with your AWS account ID and `us-east-1` with your preferred region.

Step 7: Create an ECS service

Let’s create a new ECS service that uses the task definition we created earlier:

aws ecs create-service --cluster myreactapp-cluster --service-name myreactapp-service --task-definition myreactapp-task --desired-count 1 --launch-type FARGATE --region us-east-1

Step 8: Create an Application Load Balancer

Let’s create an Application Load Balancer (ALB) to route traffic to our ECS service:

aws elbv2 create-load-balancer --name myreactapp-alb --subnets subnet-01 --security-groups sg-01 --region us-east-1

Replace `subnet-01` and `sg-01` with your preferred subnet and security group, respectively.

Step 9: Create a target group and listener

Let’s create a target group and listener to route traffic to our ECS service:

aws elbv2 create-target-group --name myreactapp-tg --protocol HTTP --port 80 --region us-east-1

aws elbv2 create-listener --load-balancer-arn  --protocol HTTP --port 80 --default-actions Type=forward,TargetGroupArn= --region us-east-1

Replace `` and `` with the ARNs of your ALB and target group, respectively.

Step 10: Configure Route 53

Let’s configure Route 53 to route traffic to our ALB:

aws route53 create-resource-record-set --hosted-zone-id  --name myreactapp.com --type A --alias-target EvaluateTargetHealth=false,AliasTarget={DNSName=,HostedZoneId=,EvaluateTargetHealth=false} --region us-east-1

Replace `` and `` with your Route 53 zone ID and ALB DNS name, respectively.

Conclusion

Congratulations! You have successfully deployed your .NET Core ReactJS application in AWS using ECR, ECS, and ALB. You can now access your application by visiting `myreactapp.com` in your browser.

This article has covered the comprehensive process of deploying a .NET Core ReactJS application in AWS. By following these steps, you can ensure seamless and efficient deployment of your application in AWS.
