上一节我们是通过创建Pipelinerun来触发流水线来进行构建，实际生产中完全自动化的实现需要借助tekton中的triggers。本文是上篇的拓展请先了解这篇文章
Tekton Triggers 是一个 Tekton 组件，它允许您从各种来源的事件中检测和提取信息，TaskRuns并PipelineRuns 根据该信息确定性地实例化和执行。Tekton 触发器还可以将从事件中提取的信息直接传递给TaskRuns和PipelineRuns。
Triggers
Tekton Triggers包含下面几个CRD来对tekton进行拓展。
EventListener- 在 Kubernetes 集群上的指定端口监听事件。指定一个或多个Triggers。Trigger- 指定当EventListener检测到事件时会发生什么。ATrigger指定 aTriggerTemplate、 aTriggerBinding和可选的 anInterceptor。TriggerTemplate- 指定资源的蓝图，例如TaskRun或PipelineRun，当您EventListener检测到事件时要实例化和/或执行该蓝图。它公开了您可以在资源模板中的任何位置使用的参数。TriggerBinding- 指定要从中提取数据的事件有效负载中的字段以及对应的字段TriggerTemplate以填充提取的值。然后，您可以使用 中的填充字段TriggerTemplate来填充关联TaskRun或中的字段PipelineRun。ClusterTriggerBinding- 的集群范围版本，TriggerBinding对于在集群中重用特别有用。Interceptor- 用于特定平台的“包罗万象”事件处理器，在TriggerBinding您执行有效负载过滤、验证（使用机密）、转换、定义和测试触发条件以及其他有用处理之前运行。一旦事件数据通过拦截器，它就会Trigger在您将有效负载数据传递给TriggerBinding.
git clone -->> make build -->> Kaniko

These Tasks are Git tasks to work with repositories used by other tasks
in your Pipeline.
The git-clone Task will clone a repo from the provided url into the
output Workspace. By default the repo will be cloned into the root of
your Workspace. You can clone into a subdirectory by setting this Task's
subdirectory param. This Task also supports sparse checkouts. To perform
a sparse checkout, pass a list of comma separated directory patterns to
this Task's sparseCheckoutDirectories param.

Workspace is strongly recommended over other volume types.
- name: basic-auth
optional: true
description: |
A Workspace containing a .gitconfig and .git-credentials file. These

Secret to this Workspace over other volume types.

}TriggerTemplate
接下来到了我们最重要的环节，我们可以通过读取 TriggerBinding 定义的参数，定义如下TriggerTemplate ，我们这里定义的是一个 PipelineRun 的模板，需要选定一个定义好的pipeline
---
apiVersion: triggers.tekton.dev/v1alpha1
kind: TriggerTemplate
metadata:
name: triggertemplate
spec:
params:
- name: gitrevision
description: The git revision
default: master
- name: gitrepositoryurl
description: The git repository url
- name: service-name
description: The service name
- name: gitref
description: The branch to checkout
resourcetemplates:
- apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
generateName: $(tt.params.service-name)-pipeline-
labels:
service: $(tt.params.service-name)
namespace: gstrain-pipeline
spec:
params:
- name: git-http-url

- name: git-revision

- name: git-ref

- name: subdirectory

# - name: package

serviceAccountName: tekton-triggers-gstrain-sa
pipelineRef:
name: gstrain-pipeline
workspaces:
- name: shared-data
persistentVolumeClaim:
claimName: my-app
- name: dockerconfig

secretName: dockerconfig
# - name: git-basic-auth
# secret:
# secretName: git-basic-auth结果
最后让我们git push来触发我们的triggers，测试下我们的流程是否正常，在kubernetes集群中可查看相应的pod任务。
[root@master ~]# kubectl get pod -l triggers.tekton.dev/eventlistener=gitlab-listener
