error: error validating "xxx-deployment.yaml": error validating data: ValidationError(Deployment.spec.template.spec.imagePullSecrets0): unknown field "volumeMounts" in io.k8s.api.core.v1.LocalObjectReference; if you choose to ignore these errors, turn validation off with --validate=false

volumeMounts: is a container child.

And volumes: is spec child.

Also volumeMounts and Vloume name should be same.

You need to move the imagePullSecret further down. It's breaking the container spec. imagePullSecret is defined at the pod spec level while volumeMounts belongs to the container spec

You have an indentation typo in your yaml, volumeMounts is under imagePullSecrets, when it should be at the same level:

     imagePullSecrets:
     - name: xxx
     volumeMounts:
     - mountPath: /data
       name: xxx-data
