Configuring Your Elastic Beanstalk Environment's Load Balancer to Terminate HTTPS

To update your Elastic Beanstalk environment to use HTTPS, you need to configure an HTTPS listener for the load balancer in your environment.

You can use the Elastic Beanstalk console to configure a secure listener and assign the certificate.

To assign a certificate to your environment's load balancer (AWS Management Console)

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Configuration.

  4. On the Load balancer configuration card, choose Modify.

    Note

    If the Load balancer configuration card doesn't have a Modify button, your environment doesn't have a load balancer.

  5. On the Modify load balancer page, choose your certificate from the SSL certificate drop-down menu.

  6. Choose Save, and then choose Apply.

Configuring a Secure Listener with a Configuration File

You can configure a secure listener on your load balancer with a configuration file like the following.

Example .ebextensions/securelistener.config

option_settings: aws:elb:listener:443: SSLCertificateId: arn:aws:acm:us-east-2:1234567890123:certificate/#################################### ListenerProtocol: HTTPS InstancePort: 80

Replace the highlighted text with the ARN of your certificate. The certificate can be one that you created in AWS Certificate Manager or one that you uploaded to IAM with the AWS CLI.

The previous example uses options in the aws:elb:listener namespace to configure an HTTPS listener on port 443 with the specified certificate, and to forward the decrypted traffic to the instances in your environment on port 80.

For more information about load balancer configuration options, see Load Balancer Configuration Namespaces.

Security Group Configuration

If you configure your load balancer to forward traffic to an instance port other than port 80, you must add a rule to your security group that allows inbound traffic over the instance port from your load balancer. If you create your environment in a custom VPC, Elastic Beanstalk adds this rule for you.

You add this rule by adding a Resources key to a configuration file in the .ebextensions directory for your application.

The following example configuration file adds an ingress rule to the AWSEBSecurityGroup security group, which allows traffic on port 1000 from the load balancer's security group.

Example .ebextensions/sg-ingressfromlb.config

Resources: sslSecurityGroupIngress: Type: AWS::EC2::SecurityGroupIngress Properties: GroupId: {"Fn::GetAtt" : ["AWSEBSecurityGroup", "GroupId"]} IpProtocol: tcp ToPort: 1000 FromPort: 1000 SourceSecurityGroupName: {"Fn::GetAtt" : ["AWSEBLoadBalancer" , "SourceSecurityGroup.GroupName"]}
