How to use a "backup node" in Jenkins?

Question

I have a job that gets triggered automatically, let's call it JobA and I have two nodes NodeA and NodeB. I want JobA to always run only on NodeA, but if NodeA is offline I want it to run on NodeB. How can is set this up?

Currently JobA only uses NodeA. If the node if offline the build is not executed.

It could be something like below. more details you can explore here

pipeline {
  agent { label 'NodeA || NodeB' }
  stages {
     stage('stage-one') {
       steps {
          ....
       }
     }
  }
}
