How to simply redirect an S3 bucket to any URL

0-s3_redirect.md

Given a vanity/campaign URL, this is the simplest way to provide a server side redirect with 0 infrastucture overhead:

1. Create a bucket
2. Open GET access to the bucket as shown below in bucket-policy-example.json (more info available in AWS S3 Static Hosting docs)
3. Enable website hosting on the bucket
4. Under Edit Redirection Rules, add XML similar to routing-rules.xml below. Read more about Routing Rules for additional options.
5. Assign an A record in Route 53 by aliasing the bucket.

  "Statement":[{
	"Sid":"PublicReadForGetBucketObjects",
        "Effect":"Allow",
	  "Principal": "*",
      "Action":["s3:GetObject"],
      "Resource":["arn:aws:s3:::example-bucket/*"
      ]
    }
  ]
}
