Setup a static website on Amazon S3

Say that you would like to host your static site on Amazon S3 with a custom domain and, of course, HTTPS.

Create two S3 buckets

To serve requests from both root domain such as codetengu.com and subdomain such as www.codetengu.com, you must create two buckets named exactly codetengu.com and www.codetengu.com.

In this post, I assume that you want to redirect www.codetengu.com to codetengu.com.

Upload your static files

$ cd /path/to/your_project_root/

$ aws s3 sync . s3://codetengu.com \
--acl "public-read" \
--exclude "*.DS_Store" \
--exclude "*.gitignore" \
--exclude ".git/*" \
--dryrun

$ aws s3 website s3://codetengu.com --index-document index.html --error-document error.html

Setup bucket policy for public accessing

In your S3 Management Console, click codetengu.com bucket > Properties > Edit bucket policy, enter:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AddPerm",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::codetengu.com/*"
        }
    ]
}

Setup www redirecting

In your S3 Management Console, click www.codetengu.com bucket > Properties > Static Website Hosting, choose Redirect all requests to another host name, type codetengu.com.

Now you're able to access your website via:

Configure a custom domain

In the "Setting Up a Static Website Using a Custom Domain" guide I mentioned above, it uses Amazon Route 53 to manage DNS records; In this post, I use CloudFlare as my website's DNS provider instead.

  • Create a CNAME for codetengu.com to point to codetengu.com.s3-website-ap-northeast-1.amazonaws.com
  • Create a CNAME for www.codetengu.com to point to codetengu.com.s3-website-ap-northeast-1.amazonaws.com

Yep, you CAN create a CNAME record for root domain on CloudFlare, just like your can add an "Alias" on Route 53.

Wait for the DNS records to propagate then visit https://codetengu.com/.
