Given the scenario:
- I have a domain example.com served from Amazon Cloudfront which reads from an S3 bucket. Route53 as DNS. All good.
- The domain uses the free SSL certificate of Amazon ACM (since I use Cloudfront I get a free certificate). All good - https://example.com works.
- I installed discourse on an Amazon Lightsail instance, available at http://read.example.com - it works since I configured Route53 to route read.example.com to the Lightsail public IP.
My question is: how can I setup the subdomain read.example.com where discourse runs, to use Amazon’s free SSL certificate? Because in this guide it says you must get your own ssl key, but I dont have one, only what Amazon has setup. And my certificate is already setup in Amazon to watch all subdomains: *.example.com, so this should work already?
I hope my question is clear. Thank you in advance for your help.
