将 YAML 转换为 JSON 时出错: yaml:第 21 行:发现违反缩进的制表符

Question

收到以下部署的错误.yaml：

admin@ip-172-20-58-79：~/kubernetes-prometheus/kube-state-metrics-configs$ kubectl apply -f deployment.yaml

error: error converting YAML to JSON: yaml: line 21: found a tab character that violate indentation

更新2：根据Arghya Sadhu的建议，添加了nodeSelector

Answer 1

我尝试了 yaml，它给了我这个错误

error: unable to recognize "kube-state-metrics.yaml": no matches for kind "Deployment" in version "apps/v1beta1"

我将apps/v1beta1更改为apps/v1来解决它，但没有收到您报告的错误。

这是我使用的yaml

apiVersion: apps/v1
kind: Deployment
metadata:
labels:
app.kubernetes.io/name: kube-state-metrics
app.kubernetes.io/version: v1.8.0
name: kube-state-metrics

Answer 2

我看不到给定的yaml有问题。我检查并部署成功。但是，仔细检查第 21 行没有使用任何选项卡进行缩进并重新部署相同的 yaml。

同时尝试在 v1.9.2 中部署 yaml

apiVersion: apps/v1
kind: Deployment
metadata:
labels:
app.kubernetes.io/name: kube-state-metrics
app.kubernetes.io/version: v1.9.2
