I want to redirect my root domain to www.domain.com. The site is published using s3 CloudFront and route53.
I have seen a lot of docs on how to redirect using s3, but I cannot do it because there's already a bucket with my root domain somewhere. So I cannot create a bucket with my root domain as the name. Also, I doubt whether this s3 redirection will work for the https request.
I haven't seen any blog on redirecting without using the s3 bucket.
So how can I redirect an HTTP/https root domain to www subdomain in aws.
You cannot redirect using Route 53 (it is a DNS configuration service afterall, whereas redirects are a HTTP operation).
If you cannot use S3, another solution could be to use use CloudFront with a Lambda@Edge function.
If the hostname is not the www domain you could perform the redirect to the www domain.
The function might look similar to the below
def lambda_handler(event, context):
request = event["Records"][0]["cf"]["request"]
response = event["Records"][0]["cf"]["response"]
# Generate HTTP redirect response with 302 status code and Location header.
if request['headers']['host'][0]['value'] != 'www.example.com':
response = {
'status': '302',
'statusDescription': 'Found',
'headers': {
'location': [{
'key': 'Location',
'value': 'https://www.example.com/{}' .format(request['uri'])
}]
}
}
return response
