How to enable SSL as well as redirect to HTTPS on Graviton Based Elastic Beanstalk Instances?

Graviton environments can have load balancers too (I have several environments like this). They are configured the same way as x86. When you are creating a new environment you have to press "Configure more options", then choose "High Availability" from the radio list at the top.

Graviton based Elastic Beanstalk instances support load balancers as non Graviton based instances do. You can attach an application load balancer to the Beanstalk instance and configure the redirection rules for moving HTTP traffic to HTTPs. When you configure your load balancer to terminate HTTPS, the connection between the client and the load balancer is secure. Backend connections between the load balancer and EC2 instances use HTTP, so no additional configuration of the instances is required.

If you need to secure the connection all the way to the EC2 instances behind the load balancer, you can configure the proxy server that runs on the instance to terminate HTTPS. Configuring your instances to terminate HTTPS connections requires the use of configuration files to modify the software running on the instances, and to modify security groups to allow secure connections.

To assign a certificate to your environment's load balancer:

1. Open the Elastic Beanstalk console, and in the Regions list, select your AWS Region.
2. In the navigation pane, choose Environments, and then choose the name of your environment from the list.
3. In the navigation pane, choose Configuration.
4. In the Load balancer configuration category, choose Edit.
5. On the Modify load balancer page:

For application load balancer, a. Choose Add listener. b. In the Application Load Balancer listener dialog box, configure the following settings:

• For Port, type the incoming traffic port, typically 443.
• For Protocol, choose HTTPS.
• For SSL certificate, choose your certificate. c. Choose Add.

For Network Load Balancer, a. Choose Add listener. b. In the Network Load Balancer listener dialog box, for Port, type the incoming traffic port, typically 443. c. Choose Add.

6. Choose Apply at the bottom of the page.
