Use SSL Provided to Host in Linux For Spring Boot

If you already have SSL configured on your Amazon Linux hostname and you want your Spring Boot application to use the same SSL configuration, you can follow these steps:

  1. Get the SSL Certificate Files: Obtain the SSL certificate files from your Amazon Linux instance. These typically include:
    • Certificate file (.crt)
    • Private key file (.key)
    • Certificate Authority (CA) bundle file (.ca-bundle or .pem)
  2. Convert SSL Certificate to PKCS12 Format (Optional): If your Spring Boot application requires a PKCS12 keystore format, you might need to convert your SSL certificate files to a PKCS12 keystore. You can do this using OpenSSL.
    openssl pkcs12 -export -out keystore.p12 -inkey private.key -in certificate.crt -certfile ca-bundle.crt
  3. Configure Spring Boot to Use SSL: Update your Spring Boot application’s configuration to use the SSL certificate files. You’ll need to specify the following properties in your or application.yml file:

  4. Restart Spring Boot Application: Restart your Spring Boot application to apply the SSL configuration changes.

With these steps, your Spring Boot application should now be running on port 8008 with the same SSL configuration as your Amazon Linux hostname. Make sure to handle any necessary permissions and access controls for the SSL certificate files.
