title: Base64 encoding is adding a new line
body: <p>I'm trying to encode a database string using base64 on the command line in linux.</p>
  <p>Once I do I add the value to a secret in kubernetes but my application is failing to connect to the database due to the db string not being accepted. There seems to be a newline getting added when I check the value in lens and this is not there in a similar cluster in the same secret</p>
  <p>jdbc:postgresql://test.xxxxxxxx.eu-west-2.rds.amazonaws.com/test</p>
  <pre><code>deirdre$ echo jdbc:postgresql://test.xxxxxxxx.eu-west-2.rds.amazonaws.com/test | base64 | tr -d &quot;\n&quot;
