Helm安装失败: configMap不能作为ConfigMap: json: ConfigMap处理，无法将bool解封为ConfigMap.data类型的string类型的结构字段

Question

试图执行helm安装，但我得到了如下错误消息：

install.go:178: [debug] Original chart version: ""
install.go:195: [debug] CHART PATH: /Users/lkkto/Dev/pipelines/manifests/helm/helm-pipeline/charts/base/charts/installs/charts/multi-user/charts/api-service

这似乎与我生成的configmap有关：

apiVersion: v1
data:
  DEFAULTPIPELINERUNNERSERVICEACCOUNT: default-editor
  MULTIUSER: true
  VISUALIZATIONSERVICE_NAME: ml-pipeline-visualizationserver
  VISUALIZATIONSERVICE_PORT: 8888
kind: ConfigMap
metadata:
  labels:
    app.kubernetes.io/name: kubeflow-pipelines
    app.kubernetes.io/component: ml-pipeline
    application-crd-id: kubeflow-pipelines
  name: pipeline-api-server-config-f4t72426kt
  namespace: kubeflow

有什么问题吗？

Answer 1

来自文档 ConfigMap.data的是一个string:string地图。在您的示例中，您将MULTIUSER设置为布尔值。

将ConfigMap更新为：

apiVersion: v1
data:
  DEFAULTPIPELINERUNNERSERVICEACCOUNT: default-editor
  MULTIUSER: 'true'
  VISUALIZATIONSERVICE_NAME: ml-pipeline-visualizationserver
  VISUALIZATIONSERVICE_PORT: 8888
kind: ConfigMap
metadata:
  labels:
    app.kubernetes.io/name: kubeflow-pipelines
    app.kubernetes.io/component: ml-pipeline
    application-crd-id: kubeflow-pipelines
  name: pipeline-api-server-config-f4t72426kt
  namespace: kubeflow

注意'true' for MULTIUSER。这将显式地将其设置为字符串。

Answer 2

只是为了支撑更多的东西。在设置入口控制器时遇到了问题。

我最初的配置如下：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: prometheus-kube-prometheus-prometheus
  namespace: monitoring
  labels:
    app: kube-prometheus-stack-prometheus
    heritage: Helm
    release: prometheus
    self-monitor: true

问题是self-monitor: true，因为它是个bool，所以Helm不能把它放入字符串中。它应该包含在类似- self-monitor: "true"这样的引号中，因此我们将在后面得到以下内容：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: prometheus-kube-prometheus-prometheus
  namespace: monitoring
  labels:
    app: kube-prometheus-stack-prometheus
    heritage: Helm
    release: prometheus
    self-monitor: "true"
