開源云原生CI/CD框架Tekton國內(nèi)部署方式
Tekton 是一款功能非常強大而靈活的 CI/CD 開源的云原生框架。致力于提供全功能、標(biāo)準(zhǔn)化的云原生 CI/CD 解決方案?！颈疚闹饕峭ㄟ^流水線自動化的將tekton鏡像同步到騰訊云倉庫，并部署tekton】
應(yīng)用鏡像
阿里云鏡像倉庫居然有限制...這次轉(zhuǎn)到騰訊云鏡像倉庫了；ccr.ccs.tencentyun.com/tektons/dashboard
Pipeline
借助GitHub Actions:
同步鏡像并生成鏡像映射文件（json）: 收集鏡像映射文件為制品；

部署Tekton
手動更新 release.yaml中的鏡像；然后kubectl apply release.yaml部署（后續(xù)有時間再優(yōu)化腳本，實現(xiàn)自動更新release.yaml）手動更新tekton-dashboard-release.yaml中的鏡像；然后部署；
