Deploy a react static site to amazon S3

Easier than you think.

Amazon S3 can be used to host a static website. Let’s walk through these simple processes.

Required Bucket Configuration

Following properties is required to make a s3-bucket to host a static site

• Enable Static Site Hosting
• Need public access to the bucket along with the objects
• A bucket policy to enable Get Object permission
• Bucket name should be the same as a domain name

We will walk through the following steps to match with all the required configurations.

Step 01: Create a Bucket

• Go to AWS Console and open S3 service
• Create a bucket and Uncheck Public Access
• Bucket name should be the same as your website domain

If we consider the website should be www.my-site.com then, the bucket name should be my-site.com

If we plan to use the site domain www.sub-domain.my-site.com then the bucket name should be the same www.sub-domain.my-site.com

• While creating a bucket, ensure you uncheck the Block all public access
• Also, acknowledge the pubic access

Step 02: Enable Static Website Hosting

• Now save the changes

Step 03: Update Bucket Policy

To update bucket-policy select the bucket and go to Permissions tab.

• Select bucket-policy and click edit
• Bucket policy be

Here, Resource is the bucket arn

This policy implies that the buckets object will be accessed publicly.

• Save the bucket-policy

Step 04: Upload Static Files

• Now select the bucket and upload all the files and directory inside the build directory

Now the site is ready and you can find the URL in the following section

• Select bucket and go to the properties section
• In properties, under the static site hosting you will find the url for the site.

Step 05: Setup Domain Using Route 53

To use the domain from Route 53 .

Go to the hosted zone and create a new recordset with the following properties

• Route name should be the same as the bucket name

• As a value, from the dropdown select the s3 website endpoint
• Also, select the region and bucket name from the value dropdown
• Route type should be A record (IPv4)
