Tekton 是一款功能非常强大而灵活的 CI/CD 开源的云原生框架。致力于提供全功能、标准化的云原生 CI/CD 解决方案。【本文主要是通过流水线自动化的将tekton镜像同步到腾讯云仓库，并部署tekton】

应用镜像

阿里云镜像仓库居然有限制...这次转到腾讯云镜像仓库了；ccr.ccs.tencentyun.com/tektons/dashboard

Pipeline

借助GitHub Actions:

1. 同步镜像并生成镜像映射文件（json）:

2. 收集镜像映射文件为制品；

This is a basic workflow to help you get started with Actionsname: Get Tekton Images

部署文件解析

1. 下载release部署yaml;

2. 解析Deployments对象中的images；

   1. tekton-pipelines-controller

   2. tekton-pipelines-webhook

   3. tekton-dashboard（最新tag）

镜像映射文件

s_image 原始镜像名称， t_image 目标镜像名称； 这里使用腾讯云的镜像仓库；

镜像映射文件可以在GitHubActions页面下载：

下载镜像脚本

解析上面生成的镜像文件，docker pull下载对应的镜像到本地；

import json
import osclass Tekton:def __init__(self):self.json_file = "tekton_images.json"self.target_registry = "ccr.ccs.tencentyun.com/tektons/"# self.registry_user = registry_user# self.registry_passwd = registry_passwddef load_json(self, data):content = json.loads(data)return contentdef down_images(self):f = open(self.json_file, 'r').read()content = self.load_json(f)# docker_login_cmd = "docker login -u {0} -p {1} {2}".format(#             self.registry_user,#             self.registry_passwd,#             self.target_registry.split("/")[0])for item in content:print("[GetImages] {}".format(item["t_image"]))docker_pull_cmd = "docker pull {0}".format(item["t_image"])# docker_tag_cmd = "docker tag {0} {1}".format(item["t_image"], item["s_image"].split("@")[0])os.system(docker_pull_cmd + "&&" + docker_tag_cmd )print("[GetImagesDone] {}".format(item))if __name__ == '__main__':t = Tekton().down_images()

部署Tekton

替换部署文件中的镜像:

1. 手动更新release.yaml中的镜像；然后kubectl apply release.yaml 部署（后续有时间再优化脚本，实现自动更新release.yaml）

2. 手动更新tekton-dashboard-release.yaml中的镜像；然后部署；

[root@master ~]# kubectl -n tekton-pipelines get pod
NAME                                          READY   STATUS    RESTARTS   AGE

tekton-pipelines-controller-b96f647bb-gff69   1/1     Running   0          13h
tekton-pipelines-webhook-76bc9c97b9-cd2m4     1/1     Running   0          13h

编写一个Ingress来暴露tekton dashboard：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:name: tekton-servicenamespace: tekton-pipelinesannotations:kubernetes.io/ingress.class: nginxnginx.ingress.kubernetes.io/proxy-body-size: 256m
