I am using Jsonnet to render Kubernetes objects, I would like to use a mixin to apply multiple volume mounts to a deployment.

An example of what I’ve tried:

config: {
  volumeMounts: [
    first: {
      mountPath: '/path/to/first',
      subPath: 'first',
      data: {},
    },
    second: {
      mountPath: '/path/to/second',
      subPath: 'second',
      data: {},
    },
  ],
}

configMap: configMap.new('config')
           + configMap.withData(
               { [config.mountPath]: config.data }
               for config in $.mountConfig
             ),

deployment: deployment.new(
              name='dep1',
              replicas='2',
              containers=[container.new('name', 'image')]
            )
            + k.util.configMapVolumeMount($.configMap, mountPath, subPath)
              for mount on $.config.VolumeMounts

Obviously an incomplete example, I can’t figure out the syntax to do a + mixin for something in somethings.
