title: Kubernetes storing key-value pair in Secret.yml
body: <p>I am wondering if it is possible to store a key-value pair in Secret.yml. 
  I want to be able to store an encryption key as a value and an id as its key which I can use to retrieve the encryption key stored in Secret.yml. </p>
  
  <p>Is such functionality available with Kubernetes?</p>
  
  <p><strong>EDIT</strong>
  I should have said in my original message, I want to be able to store multiple pairs and add pairs during the lifespan of my application and use different encryption key on the fly without/minimal update to my application.</p>
