When i try to define global podTemplate in Cloud settings it's definition is ignored.
When i try to run this basic pipeline:

pipeline {
  agent {
    kubernetes {
      label 'kubernetes'
      cloud 'kubernetes'
    }
  }
  stages {
    stage('test') {
      steps {
        container('kubectl') {
          sh "kubectl version"
        }
      }
    }
  }
}

I get following error:

java.io.IOException: container [kubectl] does not exist in pod [kubernetes-wkdgf-91gvj]

If I describe this pod before it gets terminated i see that there is only one default jnlp container defined. So basically globally defined podTemplate is ignored.

I'm attaching "clouds" part of my config.xml. Can provide any additional info required.
