Tekton 一个基于K8S的云原生的通用的 CI/CD 工具，最近闲来无事研究了一下，先说一下安装流程，由于使用的镜像都部署在国外服务器，按照官方的教程是没法正常安装的，所以我事先把使用的镜像都同步到阿里云的镜像服务器了。
使用的前提是已经有一个可用的k8s集群了，可以执行下面的脚本，事先把相关的镜像下载下来。

请务必使用v0.27.2版本的安装yaml 文件，直接执行下面的安装命令，正常情况下就可以安装完成了。
kubectl apply -f https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.27.2/release.yaml
安装完成可以看到tekton运行的pod
然后我们再安装一个tekton的dashbord，大家也可以把文件下载下来，修改一下service的端口映射，可以直接通过ip访问dashbord
kubectl apply -f https://storage.googleapis.com/tekton-releases/dashboard/previous/v0.20.0/tekton-dashboard-release.yaml
增加红色部分的配置
这样就可以直接通过http://nodeip:30097访问dashbord了
下面再给出一个镜像打包发布的完整流程配置，整个流程是从git仓库下载代码，通过kaniko执行相应的dockerfile进行程序的打包，然后把打包好的镜像发布到私有的harbor镜像仓库

上面只需要把harbor的相关地址、用户名和密码配置成自己的就可以了，其他的不需要作修改。这样正常执行完成后，就能看到执行状态是成功的绿色状态。
