Azure DevOps + helm chart = ##[警告]捕获部署元数据失败，出现错误：类型错误：无法读取 null 的属性'kind'

Question

我使用helm chart通过Azure Devops部署在AKS集群上。一切都很好，但我在部署步骤结束时看到了一个警告：

Starting: Deploy Helm chart to qa3 environment
==============================================================================
Task         : Package and deploy Helm charts
Description  : Deploy, configure, update a Kubernetes cluster in Azure Container Service by running helm commands

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
##[warning]Capturing deployment metadata failed with error: TypeError: Cannot read property 'kind' of null
Finishing: Deploy Helm chart to qa3 environment

看起来模板已经成功部署，然后运行了kubectl cluster-info，然后又运行了其他内容。我不明白是什么原因导致了这个警告：

##[警告]捕获部署元数据失败，错误为：TypeError:无法读取null 的属性"kind">

我该怎么修？

Answer 1

我似乎也遇到了同样的问题。问题是您的一个helm模板加载不正确。假设你的模板是有条件的，在条件之前有一个注释

# enables PodDisruptionBudget
{{- if .Values.pdb }}{{ if .Values.pdb.enabled }}
apiVersion: policy/v1
kind: PodDisruptionBudget
...
{{- end }}{{ end }}

在某些情况下，当if为true时，它将在没有警告的情况下工作。然而，如果它是一个false，你的模板是有点"；"空"；Azure应该跳过它。不幸的是，它不能，因为Azure在管道日志中打印了一条注释。由于没有跳过该模板，Azure搜索该模板的kind，但什么都没有，所以这就是出现警告的原因。要解决此问题，需要将注释移动到条件内部。
