By following this guide, we will learn how to make HTTPS work on your Elastic Beanstalk application. We will also understand the basic ideas that help keep your application safe. For more info, we can check related topics like how to open port 80 on EC2 or how to configure access control in AWS. Now, let’s start with the steps we need to make sure our Elastic Beanstalk application is safe and follows HTTPS rules.

Part 1 - Configure a Load Balancer to Redirect HTTP to HTTPS

We need to force HTTPS on our Elastic Beanstalk application. To do this, we will configure a Load Balancer to redirect HTTP traffic to HTTPS. Let’s follow these steps:

  1. First, we access the AWS Management Console. Then we go to the Elastic Beanstalk environment.

  2. Next, in the Load Balancer settings, we select our application. After that, we choose the Configuration section.

  3. We click on Load Balancer settings. Then we edit the Load Balancer.

  4. We add a new listener:

    • Protocol: HTTP
    • Port: 80
    • Default Action: Redirect to
    • Protocol: HTTPS
    • Port: 443
    • Redirect type: Permanent (301)

  5. We save the changes.

  6. We must ensure that we have a valid SSL certificate for our Load Balancer for the HTTPS listener. If we have not set this up, we can check Setting up SSL certificates for help.

This setup will redirect all HTTP requests to HTTPS. It helps to make sure our application is accessed securely. For more details on SSL certificates, we can check this guide.

Part 2 - Use an Application Load Balancer with HTTPS Listener

To make your Elastic Beanstalk app use HTTPS with an Application Load Balancer (ALB), we need to create an HTTPS listener and set it up right. Here are the steps:

  1. Create an SSL Certificate:

    • Get an SSL certificate from AWS Certificate Manager (ACM) or upload your own.
    • Make sure the certificate is in the same region as your Elastic Beanstalk environment.

  2. Change Load Balancer Settings:

    • Go to the AWS Management Console.
    • Click on the EC2 service and choose Load Balancers.
    • Pick your Application Load Balancer.
    • Click on the Listeners tab and then click on Add listener.
    • Set up the listener like this:
      • Protocol: HTTPS
      • Port: 443
      • Default Action: Forward to your target group.

  3. Set Up HTTPS Listener:

    • After we add the listener, click on it and choose View/edit rules.
    • Make sure the rules forward traffic to the right target group.
    • If you want HTTP traffic to go to HTTPS automatically, set up a redirect rule:
      • Add an HTTP listener on port 80.
      • Change its action to redirect to HTTPS (status code 301) with these settings:
        • Protocol: HTTPS
        • Port: 443
        • Host: #{host}
        • Path: /#{path}
        • Query: #{query}
        • Status code: HTTP_301

  4. Security Group Settings:

    • Make sure your security groups allow incoming traffic on port 443 for HTTPS.
    • Change the security group for your load balancer to allow traffic from 0.0.0.0/0 on port 443.

  5. Deploy Changes:

    • If we made any changes, we need to deploy the application to use the new settings.

  6. Test HTTPS:

    • Go to your application using https://your-domain.com to check if HTTPS is working.

For more details on how to secure your application, you can look at this guide.

This setup helps ensure that all traffic to your Elastic Beanstalk app is secure over HTTPS. It uses the good features of the Application Load Balancer. For a full guide on Elastic Beanstalk settings, see more resources here.

Part 3 - Update Security Group Rules for HTTPS

To make HTTPS work on Elastic Beanstalk, we need to allow traffic on port 443. This is for HTTPS. Here are the steps to update our security group rules:

  1. Open the Amazon EC2 Console:

    • Go to the EC2 Dashboard.

  2. Locate the Security Groups:

    • In the left menu, click on “Security Groups”.
    • Find the security group linked with our Elastic Beanstalk environment.

  3. Edit Inbound Rules:

    • Select the security group and go to the “Inbound rules” tab.
    • Click on “Edit inbound rules”.

  4. Add HTTPS Rule:

    • Click “Add rule”.
    • Set these details:
      • Type: HTTPS
      • Protocol: TCP
      • Port Range: 443
      • Source: Custom (or Anywhere 0.0.0.0/0, based on what we need)

    Here is an example of a rule:

    Type:    Protocol:   Port Range:   Source:
HTTPS    TCP         443           0.0.0.0/0

  5. Save Rules:

    • Click “Save rules” to make the changes.

By updating the security group rules for HTTPS traffic, we help our Elastic Beanstalk app to safely handle requests over SSL. For more setup details, check the Elastic Beanstalk documentation about HTTPS.

Part 4 - Modify .ebextensions for HTTP to HTTPS Redirection

To make your Elastic Beanstalk app use HTTPS, we can use the .ebextensions config files. First, we need to create a file called http-to-https.config in the .ebextensions folder of our app. Next, we will add this configuration:

files:
  "/etc/httpd/conf.d/https_redirect.conf":
    mode: "000644"
    owner: root
    group: root
    content: |
      <VirtualHost *:80>
          ServerName yourdomain.com
          Redirect permanent / https://yourdomain.com/
      </VirtualHost>

commands:
  remove_default_httpd_conf:
    command: "rm -f /etc/httpd/conf.d/welcome.conf"

Key Points:

  • We need to change yourdomain.com to our real domain name.
  • This config will send all HTTP requests to HTTPS.
  • We must make sure our Elastic Beanstalk environment listens on port 80 for HTTP and port 443 for HTTPS.

After we create this file, we should deploy our app to see the changes. This way works well to redirect HTTP to HTTPS in AWS Elastic Beanstalk. For more info on Elastic Beanstalk configs, check this guide.

Part 5 - Set up a Custom Domain with SSL Certificates

To set up a custom domain with SSL certificates for our Elastic Beanstalk application, we can follow these steps.

  1. Register Your Domain: First, we need to choose a domain registrar. This can be Route 53, GoDaddy, or any other. Then, we register our domain name.

  2. Obtain an SSL Certificate:

    • We can use AWS Certificate Manager (ACM) to ask for a public certificate.
    • Go to the AWS Certificate Manager and request a certificate by putting in our domain name.

  3. Validate Your Domain:

    • We can validate our domain by using DNS validation or email validation. We should follow the steps given by ACM to finish this process.

  4. Configure Elastic Beanstalk Environment:

    • Next, we go to our Elastic Beanstalk console.
    • We select the environment we want to set up.
    • Click on “Configuration” and then “Load balancer”.

  5. Add HTTPS Listener:

    • In the Load Balancer settings, we need to add an HTTPS listener.
    • We select the SSL certificate we created in ACM.

  6. Redirect HTTP to HTTPS:

    • We have to make sure that our application or load balancer redirects HTTP traffic to HTTPS. We can do this using a rewrite rule in our web server configuration. This can be done in Nginx or Apache.

  7. Update Domain DNS Records:

    • Now, we go to our domain registrar. Here, we update the DNS records to point to our Elastic Beanstalk environment. We can use an A record for the main domain or a CNAME for subdomains.

  8. Test the Configuration:

    • Finally, we can check our application using the custom domain. We access it via https://yourdomain.com to see if the SSL certificate is set up right and working.

If we need more help on setting up our custom domain, we can look at the AWS documentation on using AWS Certificate Manager.

Part 6 - Verify HTTPS Configuration in Your Application

We need to check if HTTPS is set up right in our Elastic Beanstalk application. Here are the steps we can follow:

  1. Access Your Application: Open a web browser. Go to your application’s URL with https://. Make sure the page loads without any security messages.

  2. Check SSL Certificate:

    • Click on the padlock icon in the address bar.
    • Look at the certificate details. We need to confirm it is valid and set up correctly for our domain.

  3. Use cURL for Testing: We can use cURL in the terminal to see the HTTPS response:

    curl -I -L https://your-domain.com

    We need to check that the HTTP response status is 200 OK. It should follow redirects if needed.

  4. Test HTTP to HTTPS Redirection: To check if HTTP requests go to HTTPS, we run this cURL command:

    curl -I http://your-domain.com

    We should get a 301 or 302 response that redirects us to the HTTPS URL.

  5. Check for Mixed Content: Open the browser’s developer tools by pressing F12. Go to the Console tab. Look for mixed content warnings. This means HTTP resources load on an HTTPS page. We must make sure all resources like images, scripts, and styles load over HTTPS.

  6. Use Online Tools: We can use online SSL checkers like SSL Labs to check our site’s HTTPS setup. This tool gives us a full report on our SSL certificate, setup, and any problems we might have.

By doing these checks, we can make sure our Elastic Beanstalk application uses HTTPS correctly. This helps keep things safe and gives users a better experience. If we want more detailed steps on setting up security groups or changing settings, we can look at other resources like how to fix API Gateway CORS.

Frequently Asked Questions

We often need to create an HTTPS listener on an Application Load Balancer. For more details, we can check our guide on how to force HTTPS on Elastic Beanstalk.

2. What is the difference between HTTP and HTTPS in Elastic Beanstalk?

HTTP means HyperText Transfer Protocol. It is not secure. HTTPS means HTTP Secure. It uses SSL/TLS to encrypt data between the client and server. By using HTTPS on Elastic Beanstalk, we make our application safer. It helps protect sensitive information. For more information, we can read our article on the technical differences between HTTP and HTTPS.

3. Can we use a custom domain with HTTPS on Elastic Beanstalk?

Yes, we can use a custom domain with HTTPS on Elastic Beanstalk. We usually need to set up SSL certificates for our domain. Then we configure the load balancer to handle HTTPS traffic. For a step-by-step guide, we can visit our resource on how to set up a custom domain with SSL certificates.

4. How can we enforce HTTPS redirection in our Elastic Beanstalk application?

To enforce HTTPS redirection in our Elastic Beanstalk application, we can change the .ebextensions configuration. This will help redirect HTTP traffic to HTTPS automatically. It makes sure that all users access our application securely. For more details, we can see our article on modifying .ebextensions for HTTP to HTTPS redirection.

5. What are the security group rules needed for HTTPS on Elastic Beanstalk?

When we configure HTTPS on Elastic Beanstalk, we need to update our security group rules. We must allow inbound traffic on port 443 for HTTPS. This allows our application to get secure requests. For more information on this, we can refer to our guide on how to update security group rules for HTTPS.
