开源云原生CI/CD框架Tekton国内部署方式
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；
This is a basic workflow to help you get started with Actions
name: Get Tekton Images
env:
VERSION: v0.29.0
on:
push:
paths:
- '.github/workflows/tekton.yaml'
- 'tekton/**'
jobs:
build:
runs-on: ubuntu-18.04
steps:
- uses: actions/checkout@v2

grep -v "#" release.yaml | grep -v "^$" > release1.yaml ; sed -i 's/\-\-\-/###/g' release1.yaml
python3 tekton/get_tekton_images.py ${

- uses: actions/upload-artifact@v2
with:

部署文件解析
下载release部署yaml;
解析Deployments对象中的images；

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；
