I use ConfigMap as Volume in the deployment. I'm trying to update a deployment with different Volume and VolumeMount.(see example below)

I tried all the following ways:

(I use io.fabric8.kubernetes.api to do the operations on kubernetes.)

1)

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).replace(deployment);

2)

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).createOrReplace(deployment);

3)

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).cascading(false).replace(deployment);

4)

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).edit().editSpec().editTemplate().editSped().removeAllFromVolumes(volumes).endSpec().endTemplate().endTemplate().endSpec().done();

5)

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).edit().editSpec().editTemplate().editSped().removeFromVolumes(volume).endSpec().endTemplate().endTemplate().endSpec().done();

All the above commands don't work!...

I also tried :

client().extensions().deployments().inNamespace(namespaceName).withName(deploymentName).edit().editSpec().editTemplate().editSped().AddToVolumes(volume).endSpec().endTemplate().endTemplate().endSpec().done();

and it works.

i.e. only ADD works, but REMOVE doesn't work....

Is it a BUG or not ? Did I use it in the right way? I just want to update the deployment with different Volume (ConfigMap type) and VolumeMount, how should I do? Thank you!

Example: The old Deployment is like this: (I only show the main part)

kind: Deployment
metadata:
  name: d2
  namespace: n1
  spec:
    replicas: 1
    template:
      metadata:
        creationTimestamp: null
      spec:
        containers:
        - image: x.x.x.x
          imagePullPolicy: IfNotPresent
          name: c2
          volumeMounts:
          - mountPath: /var
            name: configmapvolume1
          - mountPath: /var/a
            name: configmapvolume2
        volumes:
        - configMap:
            defaultMode: 420
            items:
            - key: a.yml
              path: a.yml
            name: a
          name: configmapvolume1
        - configMap:
            defaultMode: 420
            items:
            - key: c.yml
              path: c.yml
            name: a
          name: configmapvolume2
