How to prevent auto updating vault secrets after pod restarts

Use case

  1. Application A deployed using k8s and secrets are rendered and injected into the application
  2. application has one secret - secret1 with value = 1 i.e. secret1 = value1
  3. now using vault UI we changed the secret1 = value1 to secret1 = value2
  4. Application A is now rescaled
  5. Here, Application A must not get secret1 = value2 but it should retain with secret1 = value1
  6. How to ensure this?
