由于“没有匹配所有谓词的可用节点:MatchInterPodAffinity(1)”，Kubernetes-Pod调度失败。

请你帮忙。

从链接的文档中：

除了labelSelector和topologyKey，您还可以选择指定labelSelector应该匹配的名称空间的列表名称空间（这与labelSelector和topologyKey在定义的同一级别）。如果省略，则默认为出现关联/反关联定义的pod的命名空间。如果已定义但为空，则表示“所有命名空间”

以下是基于YAML的示例：

affinity:
podAffinity:
  requiredDuringSchedulingIgnoredDuringExecution:
  - labelSelector:
      matchExpressions:
      - key: app
        operator: In
        values:
        - {{ .Values.albId }}
    topologyKey: "{{ .Values.topologyKey }}"
    namespaces: [] # empty array
podAntiAffinity:
  requiredDuringSchedulingIgnoredDuringExecution:
  - labelSelector:
      matchExpressions:
      - key: app
        operator: In
        values:
        - {{ .Values.name }}
    topologyKey: "{{ .Values.topologyKey }}"
    namespaces: []
