执行 `helm install` 命令时 `deployment.yaml` 出现验证错误

Question

我正在尝试使用 Helm 图表部署到 Azure Kubernetes 集群。尝试执行以下命令时：

helm install --namespace custom-namspace my-project ./my-project

我收到以下错误：

Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: [ValidationError(Deployment.spec.template.spec.volumes[1]): unknown field "namespace" in io.k8s.api.core.v1.Volume, ValidationError(Deployment.spec.template.spec.volumes[1]): missing required field "name" in io.k8s.api.core.v1.Volume]

以下是我的 deployment.yaml 文件：

       volumes:

        {{- with .Values.nodeSelector }}
       nodeSelector:

       {{- end }}
       {{- with .Values.affinity }}
       affinity:

       {{- end }}
       {{- with .Values.tolerations }}
       tolerations:
       {{- toYaml . | nindent 8 }}
       {{- end }}

我也提到过这个 Github issue 但它没有达到目的。

这是我第一次从事 Kubernetes 部署和 Helm chart 方面的工作。如果有任何帮助，我将不胜感激。

我尝试使用以下命令调试 helm 图表：

helm template --dry-run --debug --namespace my-namespace my-project ./my-project

Helm Template 通过从 values.yaml 文件中查找所有变量字段值，在您的控制台上本地呈现图表。

--dry-run 基本上模拟了一个 helm install 命令，但没有连接到您的实际 kubernetes 集群。

--debug 帮助您获得上述命令的更详细输出。

到这里，我知道问题中显示的错误是由 requirements.yaml

提供的依赖关系表引起的

这是执行 helm template 命令时在控制台中的样子。我试图用评论来解释问题所在。

         - namespace: my-namespace   # This is unknown field here. Need to be removed.
