Collabera docker on AWS

Greetings everyone,

Here is my present configuration
On AWS Elastic Kubernetes Service (EKS), I run a web app with multiple tenants. The domain I own is “*”.

I own a certificate that was issued by AWS ACM.

On an Ubuntu instance on AWS, I have mounted a Docker image of Collabera.

One SSL-related issue I’m having is when my webapp tries to connect to a Docker instance. Since AWS loadbalancer handles SSL automatically, I’d like to use it. Loadbalancer has actually sent requests to my Ubuntu instance.

Adding a certificate from Let’s Encrypt didn’t work at first.

In general, does my setup appear decent? Does private cloud hosting come with any kind of documentation?

Much obliged.
