AWS Transport for Caddy

Note

The module is not validated -- yet! I don't use AWS personally, so feedback is welcome. Consider it WIP until this is removed. The configuration structure is also subject to change.

This module aims to injects the AWS V4 Signature for requests proxied to AWS services. It also implicitly calculates and sets the x-amz-content-sha256 header value.

Example

Caddyfile

example.com {
	reverse_proxy https://{$BUCKET_NAME}.s3.{$AWS_REGION}.amazonaws.com {
		header_up Host {upstream_hostport}
		transport aws {
			access_id {$AWS_ACCECSS_ID}
			secret_key {$AWS_SECRET_KEY}
			region {$AWS_REGION}
			service {$AWS_SERVICE}

			# other 'http' transport directives per:
			# https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#the-http-transport 
		}
	}
}
