under the Application Delivery special interest group (SIG) in the Cloud Native Computing Foundation (CNCF) [1.8]. By the end of 2020, the GitOps Working Group was bootstrapped and became an official working certification through standardized documents and code. OpenGitOps is currently a sandbox project within the CNCF. In October 2021, the GitOps Working Group released the OpenGitOps Principles [1.10], a set of principles https://www.weave.works [1.7] https://www.weave.works/blog/the-history-of-gitops [1.8] https://www.cncf.io [1.9] https://opengitops.dev [1.10] https://github.com/open-gitops/documents/releases/tag/v1

yaml在用sed replace嗎? •容易出錯 •把他打包成Helm chart嗎？在帶入variable 嗎？ •複雜度過高 7 Kustomize •讓無模板的yaml可以支援多種用途 •CNCF special interest groups (SIGs) 贊助 •Kubernetes 1.14版開始支援 8 Sample Repoitory •https://github.com

选型原则 • 基于开源⽅方案，⼆二次开发 • 具备现代时间序列列数据库的特性 • 活跃项⽬目,具有成熟的⽣生态环境 结论 • prometheus • ⽀支持任意维度label • cncf基⾦金金会 metric • 40w+/s的指标采集 • 10k+ 监控⽬目标 • 10+ prometheus节点 现状: • 性能 • ⾼高可⽤用 • 分布式 • 使⽤用成本
