Here I show how I would host a static web site on AWS using S3, Route53 and CloudFront.

S3: Create an S3 bucket for your website

Open the AWS console navigate to S3 and create a bucket

Note uncheck the "Block all public access"

S3: Configure Bucket for Static Website Hosting

Under Properties of the bucket, edit the "Static website hosting" section

S3: Configure Bucket Policy for Public Access

Add the bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::<bucket-name>/*"
        }
    ]
}

Create Static Web App

$> npx create-react-app staticsite

Enter fullscreen mode Exit fullscreen mode

Build a static site from react app

$> npm run build
Enter fullscreen mode Exit fullscreen mode

The static site now needs to be uploaded to S3 bucket

S3: Upload application to the bucket

Domain Name Validation Config: Add a CNAME on your domain registrar for validation

Name: _e0bexxxxxxxxxxxxx.staticsite.nanosoft.co.za
Type: CNAME, 
Value: _775axxxxxxxxxxxxxxxx.xxxxxxxxxx.acm-validations.aws.
Enter fullscreen mode Exit fullscreen mode

Note: do not include the dot at the end of the Name.

This validation might take up to 30 minutes for the changes to propagate.

Once you subdomain has been validated the status will change to "Issued" and you are now ready to use the certificate.

DNS Config: Add a CNAME on your domain registrar for AWS Web hosting

Name: staticsite.nanosoft.co.za
Type: CNAME, 
Value: s3-website.af-south-1.amazonaws.com.

Enter fullscreen mode Exit fullscreen mode

To check the progress of the DNS propagation use the tool:
https://dnschecker.org/#CNAME/staticsite.nanosoft.co.za

After a few minutes you'll be able to browse your secure custom domain url for your static site.

Done!
