生成tekton dashboard

我们在之前的（安装和构建ci）实践中，用到都是tekton cli，查看ci执行情况都是通过logs，不是很友好。 tekton dashboard提供了很多的ui界面。这里我们来安装并使用。

1. 创建dashboard.yaml

apiVersion: v1
kind: Namespace
metadata:
  labels:
    app.kubernetes.io/instance: default
    app.kubernetes.io/part-of: tekton-dashboard
  name: tekton-dashboard
---
apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  labels:
    app.kubernetes.io/component: dashboard
    app.kubernetes.io/instance: default
    app.kubernetes.io/part-of: tekton-dashboard
  name: extensions.dashboard.tekton.dev
spec:
  group: dashboard.tekton.dev
  names:
    categories:
      - tekton
      - tekton-dashboard
    kind: Extension
    plural: extensions
    shortNames:

      - exts
  preserveUnknownFields: false
  scope: Namespaced
  versions:
    - additionalPrinterColumns:
        - jsonPath: .spec.apiVersion
          name: API version
          type: string
        - jsonPath: .spec.name
          name: Kind
          type: string
        - jsonPath: .spec.displayname
          name: Display name
          type: string
        - jsonPath: .metadata.creationTimestamp
          name: Age
          type: date
      name: v1alpha1
      schema:
        openAPIV3Schema:
          type: object
          x-kubernetes-preserve-unknown-fields: true
      served: true
      storage: true
      subresources:
