4.8. 在 Pipeline 中添加触发器

流程

1. 复制以下 TriggerBinding YAML 示例文件的内容并保存：

   apiVersion: triggers.tekton.dev/v1alpha1
   kind: TriggerBinding
   metadata:
     name: vote-app
   spec:
     params:
     - name: git-repo-url
       value: $(body.repository.url)
     - name: git-repo-name
       value: $(body.repository.name)
     - name: git-revision
       value: $(body.head_commit.id)

2. 创建 TriggerBinding:

   $ oc create -f <triggerbinding-yaml-file-name.yaml>

   或者，您可以直接从 pipelines-tutorial Git 存储库创建 TriggerBinding：

   $ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/release-tech-preview-1/03_triggers/01_binding.yaml

3. 复制以下 TriggerTemplate YAML 示例文件的内容并保存：

   apiVersion: triggers.tekton.dev/v1alpha1
   kind: TriggerTemplate
   metadata:
     name: vote-app
   spec:
     params:
     - name: git-repo-url
       description: The git repository url
     - name: git-revision
       description: The git revision
       default: master
     - name: git-repo-name
       description: The name of the deployment to be created / patched
   
     resourcetemplates:
     - apiVersion: tekton.dev/v1alpha1
       kind: PipelineResource
       metadata:
         name: $(params.git-repo-name)-git-repo-$(uid)
       spec:
         type: git
         params:
         - name: revision
           value: $(params.git-revision)
         - name: url
           value: $(params.git-repo-url)
   
     - apiVersion: tekton.dev/v1alpha1
       kind: PipelineResource
       metadata:
         name: $(params.git-repo-name)-image-$(uid)
       spec:
         type: image
         params:
         - name: url
           value: image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/$(params.git-repo-name):latest
   
     - apiVersion: tekton.dev/v1beta1
       kind: PipelineRun
       metadata:
         name: build-deploy-$(params.git-repo-name)-$(uid)
       spec:
         serviceAccountName: pipeline
         pipelineRef:
           name: build-and-deploy
         resources:
         - name: git-repo
           resourceRef:
             name: $(params.git-repo-name)-git-repo-$(uid)
         - name: image
           resourceRef:
             name: $(params.git-repo-name)-image-$(uid)
         params:
         - name: deployment-name
           value: $(params.git-repo-name)

4. 创建 TriggerTemplate:

   $ oc create -f <triggertemplate-yaml-file-name.yaml>

   另外，您还可以从 pipelines-tutorial Git 存储库直接创建 TriggerTemplate：

   $ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/release-tech-preview-1/03_triggers/02_template.yaml

5. 复制以下 EventListener YAML 示例文件的内容并保存：

   apiVersion: triggers.tekton.dev/v1alpha1
   kind: EventListener
   metadata:
     name: vote-app
   spec:
     serviceAccountName: pipeline
     triggers:
     - bindings:
       - name: vote-app
       template:
         name: vote-app

6. 创建 EventListener:

   $ oc create -f <eventlistener-yaml-file-name.yaml>

   或者，您可以直接从 pipelines-tutorial Git 存储库创建 EvenListener：

   $ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/release-tech-preview-1/03_triggers/03_event_listener.yaml

7. 将 EventListener 服务以 OpenShift Container Platform 路由的形式公开，以便公众可以访问它：

   $ oc expose svc el-vote-app
