Lightsail Containers, SSL Certificates, and Subdomains Inquiries

What you need is a Load Balancer. On the Domain hosted outside your AWS environment, you can configure a DNS records to point to the Load Balancer. Traffic will be like: (Domain) -> (Load Balancer) -> (Lightsail Containers)

You can also explore AWS Certificate manager (ACM). ACM is a service that can help you create SSL certificates for free. You can install a certificate created using ACM on your load balancer on your port listener.

Here are some useful articles to get you started: https://repost.aws/knowledge-center/lightsail-add-application-load-balancer https://docs.aws.amazon.com/elasticloadbalancing/latest/application/listener-update-certificates.html

Hello,

The following documentation includes steps for configuring your container service with a custom domain and SSL/TLS certificate:

• Enabling and managing custom domains for your Amazon Lightsail container services
• Creating SSL/TLS certificates for your Amazon Lightsail container services
• SSL/TLS certificates in Lightsail

Here is one callout from the documentation about the pre-requisites for configuring a custom domain for your container service:

If you have no certificates, then you must first create and validate an SSL/TLS certificate for your domains, before you can attach it to your container service.

To use a custom domain with your Lightsail container service, the certificate for the domain must be managed in Lightsail.
