How to Configure SSL Certificate for AWS Elastic Beanstalk

In this post, we will discuss how to configure an SSL certificate for an application running on AWS Elastic Beanstalk. Securing your application with SSL is important to ensure the security and privacy of your users' data.

Prerequisites

Before getting started, you should have the following:

  • An AWS account
  • An application deployed on AWS Elastic Beanstalk
  • A domain name that you want to secure with SSL

Step 1: Obtain SSL Certificate

The first step is to obtain an SSL certificate for your domain. You can obtain an SSL certificate from a trusted Certificate Authority such as Let’s Encrypt, AWS Certificate Manager, or any other SSL certificate provider.

Step 2: Deploying the SSL Certificate

Once you have obtained the SSL certificate, you need to deploy it to the AWS Certificate Manager (ACM). This provides an integrated service that makes it easier to deploy SSL/TLS certificates for use with AWS services.

// Example code to deploy SSL certificate to AWS ACM

The AWS Certificate Manager documentation provides detailed instructions on how to import or request a new SSL/TLS certificate and deploy it to your AWS account.

Step 3: Configuring Elastic Beanstalk Environment

After the SSL certificate is deployed to ACM, you can configure your Elastic Beanstalk environment to use the SSL certificate. You need to update the environment configuration to enable HTTPS and specify the SSL certificate ARN (Amazon Resource Name).

For Java applications, you can do this by updating the .ebextensions configuration files to add a listener rule for HTTPS. Here's an example of how you can configure the SSL listener for your Elastic Beanstalk environment in the .ebextensions config file.

Resources:
  sslSecurityGroupIngress2:
    Type: AWS::EC2::SecurityGroupIngress
    Properties:
      GroupId: {"Fn::GetAtt": ["AWSEBSecurityGroup", "GroupId"]}
      IpProtocol: tcp
      ToPort: 443
      FromPort: 443
      CidrIp: 0.0.0.0/0

option_settings:
  aws:elbv2:listener:443:
    ListenerEnabled: true
    Protocol: HTTPS
    SSLCertificateArns: arn:aws:acm:region:account-id:certificate/certificate-id

Make sure to replace region, account-id, and certificate-id with the appropriate values for your SSL certificate.

Step 4: Deploying Changes

After updating the environment configuration, you need to deploy the changes to your Elastic Beanstalk environment. You can use the AWS Management Console, AWS CLI, or any other deployment tool of your choice to deploy the updated configuration.

Step 5: Testing

Once the changes are deployed, you should test the HTTPS configuration to ensure that your application is now accessible over HTTPS. You can do this by accessing your application using the HTTPS protocol and verifying that the SSL certificate is being used correctly.

The Closing Argument

In conclusion, securing your application with an SSL certificate is crucial for ensuring the confidentiality and integrity of data transmitted over the internet. By following the steps outlined in this post, you can successfully configure an SSL certificate for your application running on AWS Elastic Beanstalk. This will help you provide a secure and trustworthy experience for your users.

By following this guide, you can confidently secure your application on AWS Elastic Beanstalk with an SSL certificate, ensuring the security and privacy of your users' data. Remember to periodically renew your SSL certificate to maintain a secure setup.
