I’m not sure if you have actually looked at the official Discourse install guide which is the only supported install method I’ve heard of.
Other users have referred you to it in your other topic, e.g. this reply:
https://meta.discourse.org/t/can-not-configure-my-bitnami-discourse-instance-to-send-out-mails/101618/2?u=remah
You will see on other topics that AWS/Bitnami installs are not supported although people may still be able to help you, e.g. as in this topic:
https://meta.discourse.org/t/just-installed-discourse-on-aws/86146?u=remah
FYI, here is some background on the AWS install guide that you found.
The blog owner is a user here, @stroupaloop, although I haven’t seen him posting for a while.
He had a couple of topics on AWS that I read when i first joined:
- Pointing to the blog post you refer to: Discourse deployment using AWS
- Covering some issues he had: Setting up Discourse with SSL on Docker with AWS ELB breaks and returns 503 Service Unavailable (Back-end server is at capacity).
