Helm 安装失败：configMap 无法作为 ConfigMap 处理：json：无法将 bool 解组到字符串类型的 Go struct 字段 ConfigMap.data 中

Question

尝试安装 helm 但收到如下错误消息：

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

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

这有什么问题吗？

Answer 1

来自 docs ConfigMap.data 是一个

string:string

地图。在您的示例中，您将

MULTIUSER

设置为布尔值。

将您的 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'

代表

MULTIUSER

。这明确地将其设置为字符串。

Answer 2

只是为了进一步支持这一点。设置入口控制器时遇到此问题。

我的初始配置是这样的：

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

问题在于

self-monitor: true

，Helm 无法将其编组为字符串，因为它是布尔值。它应该用这样的引号括起来 -

self-monitor: "true"

，所以我们之后会有这个：

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"
