Redirect Http Url to Https in Elastic beanstalk loadbalancer

Question

I've my spring boot app running on tomcat EC2 instances behind the Loadbalancer, which has configured with Https and internelly using Http.

I want to redirect url requests to HTTP to HTTPS.

I found this document from AWS Support

As it says I need to config the Apache backend with the following config

RewriteEngine On

RewriteCond %{HTTP:X-Forwarded-Proto} =http

RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

My Question is where to add these config?

There is another document says i need to add .ebextensions directory to the webapp directory and place configurations there. If that is the case, then what is the directory structure and config file format ?

Create a folder .ebextensions in the root of your project (and make sure it is in the root of the bundle you're uploading to Elastic Beanstalk. Something like this:

~/workspace/my-app/
|-- .ebextensions
|   -- httpd
|      -- conf.d
|         -- myconf.conf
-- index.jsp

in myconf.conf

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

There is a whole article on customizing the Java apps running in Elastic Beanstalk Tomcat: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-tomcat-platform.html Have a look for more info.

Thanks for the reply, I'll test it.

It is not working. In the logs I found "Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration"

I mark it as accepted as it is answering the main question about directory structure. For full answer check the answer below. stackoverflow.com/questions/44805261/…

Found the solution create a config file in the following location

~/workspace/server/
|-- .ebextensions
|   -- httpd
|      -- conf.d
|         -- abc.conf

with the following content

<VirtualHost *:80>
   LoadModule rewrite_module modules/mod_rewrite.so

   RewriteEngine On
   RewriteCond %{HTTP:X-Forwarded-Proto} !https
   RewriteCond %{HTTP_USER_AGENT} !ELB-HealthChecker
   RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

   <Proxy *>
     Require all granted
   </Proxy>

   ProxyPass / http://localhost:8080/ retry=0
   ProxyPassReverse / http://localhost:8080/
   ProxyPreserveHost on

   ErrorLog /var/log/httpd/elasticbeanstalk-error_log

</VirtualHost>

Load mod_rewrite is required in newer Tomcat installations.
