helm version ：

我在升级时遇到间歇性错误。在这种情况下，我更改了spec.template.spec.resources apiVersion: apps/v1的DaemonSet：
舵：

Error: UPGRADE FAILED: failed to create patch: failed to get versionedObject: Object 'apiVersion' is missing in 'unstructured object has no version' && failed to create patch: unable to find api field in struct PodSpec for the json field "resources"

这似乎与＃3382相似，但这不是CRD。

最有用的评论

根本原因是去模板化。

# some comment
{{- if .Values.global.rbacEnable -}}
apiVersion: v1
kind: ServiceAccount
...

猜猜会发生什么？

# some comment apiVersion: v1
kind: ServiceAccount
...

Helm高兴地尝试使用无效对象，但失败了：
Error: failed to create patch: failed to get versionedObject: Object 'apiVersion' is missing in 'unstructured object has no version'

验证对象的一种方法是使用kubectl。我很高兴有另一种选择：

TMP_DIR=/tmp/manifests
mkdir -p $TMP_DIR
helm template $HELM_OPTS $HELM_CHART_PATH \
      | csplit -f $TMP_DIR/ --suppress-matched -q -z - '/^---$/' '{*}'
for f in $TMP_DIR/*;  do
  kubectl apply --dry-run -f $f || exit 1
done

看起来这是一个格式错误的Daemonset（资源未正确缩进）。有没有办法暴露捕捉到这一点的Kubernetes验证？

error: error validating "/tmp/test.yaml": error validating data: ValidationError(DaemonSet.spec.template.spec): unknown field "resources" in io.k8s.api.core.v1.PodSpec; if you choose to ignore these errors, turn validation off with --validate=false

嗨@ hobti01

我们是否可以解决此问题，以打开功能要求公开k8s验证？
