Parameters with Kubernetes Manifest & Using SpEL

Question: How do I dynamically promote a build with parameters in a manifest file in Spinnaker using Kubernetes? Answer:

• The first step is to understand how to use parameters in your kubernetes manifest file. Here is a link to some good documentation: Parameterize Kubernetes Manifests* The second step is to create a pipeline expression to dynamically decide where to deploy the code based on some action. For our example we are using a manual judgement stage to determine if the code should go to Prod or Staging. Example: Promote:${#judgement('Promote') == '' ? parameters['namespace'] : #judgement('Promote')}
