云原生CI/CD框架Tekton国内部署方式-开源-知优网

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:

同步镜像并生成镜像映射文件(json):
收集镜像映射文件为制品;

部署文件解析

1.下载release部署yaml;

2.解析Deployments对象中的images;

b.tekton-pipelines-webhook

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;

importjson
importos
classTekton:
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_passwd
defload_json(self,data):
content=json.loads(data)
returncontent
defdown_images(self):
f=open(self.json_file,'r').read()
content=self.load_json(f)
#docker_login_cmd="dockerlogin-u{0}-p{1}{2}".format(
#self.registry_user,
#self.registry_passwd,
#self.target_registry.split("/")[0])
foritemincontent:
print("[GetImages]{}".format(item["t_image"]))
docker_pull_cmd="dockerpull{0}".format(item["t_image"])
#docker_tag_cmd="dockertag{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:

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

[root@master~]#kubectl-ntekton-pipelinesgetpod
