Error: spec.volumes[1].configMap.name: Required value, spec.containers[0].volumeMounts[1].name: Not found

Symptom:

  We use partial yaml below to create a statefulset with mount a volume for configmap.It is successful
apiVersion: apps/v1
kind: StatefulSet
......  
    spec:
      volumes:
        - name: pgreplica-config
          configMap:
            name: pgconfigmap
........
When we try to use client-go to do the same thing.

o.pgreplicamaster.Spec.Template.Spec.Volumes = []corev1.Volume{
{Name: "pgreplica-config",
 VolumeSource: corev1.VolumeSource{ 
   ConfigMap: &corev1.ConfigMapVolumeSource{
    Items: corev1.KeyToPath{{Key: "name",Path: pgconfigmap}},
   },
   },
    
},
}
We hit error
Error: spec.volumes[1].configMap.name: Required value, spec.containers[0].volumeMounts[1].name: Not found

Solution

Refer k8s doc of ConfigMapVolumeSource
There is LocalObjectReference which we should use, instead of using Items
Update code as below to make it work
o.pgreplicamaster.Spec.Template.Spec.Volumes = []corev1.Volume{
{Name: "pgreplica-config",
VolumeSource: corev1.VolumeSource{
   ConfigMap: &corev1.ConfigMapVolumeSource{
    LocalObjectReference: corev1.LocalObjectReference{Name: "pgconfigmap"},
   },
   },
   
},
}
