从十到千，响应团队规模的敏捷与DevOps实践-冯斌

Python与Devops Law 目录 CONTENTS Devops技术栈 Devops构建示例 Python工具二次开发 Devops DevOps 是一个完整的面向IT运维的工作流，以 IT 自动化以及持续集成（CI）、持续部署（CD）为 基础，来优化程式开发、测试、系统运维等所有 环节 构建Devops之前面临的问题 Devops 过程包含，代码构建打包、测试、部署、发布、监控、回滚等等一个 过程包含，代码构建打包、测试、部署、发布、监控、回滚等等一个 项目的闭环、快速构建以上过程。 构建Devops常用软件技术栈 •代码管理（SCM）：GitHub、GitLab、SubVersion •构建工具：Ant、maven •自动部署：ansible、saltstack、puppet •持续集成（CI）：Jenkins •配置管理：Ansible、Chef、Puppet、SaltStack •容器：Docker、kvm tack、Apache Mesos、swarm •服务注册与发现：Zookeeper、etcd、Consul •脚本语言：python、ruby、shell •日志管理：ELK、Logentries •系统监控：zabbix、prometheus 前东家关于Devops的一些实践 Devops传统方式下构建示例 Devops发布流程需要考虑几个问题 1、发布什么应用，发布到哪里（CMDB）

The DevOps Handbook – Parts 5 & 6 – Part 5: The Third Way – The Technical Practices of Continual Learning and Experimentation; 1. Introduction a. Goal – practices to enable learning as quickly, frequently improvement blitz – dedicated and concentrated period of time to address a given issue b. Target DevOps Dojo and 30-Day Challenge – teams work with dedicated Dojo coaches and engineers, execute 2-day from other organizations & teams iv. Participate in peer reviews e. SHARE YOUR EXPERIENCES FROM DEVOPS CONFERENCES i. Cost is always a consideration. BUT, encourage attendance at conferences, give talks

The DevOps Handbook – Part 4: The Second Way – The Technical Practices of Feedback 1. Introduction a. Goal – Implement fast feedback loops i. Enable working towards shared goals ii. See problems as without requiring time-sucking configuration changes or complicated processes.” iv. 2015 State of DevOps Report – high performers had MTTR 168x faster than low performers b. CREATE OUR CENTRALIZED TELEMETRY Production System – “people closest to a problem typically know the most about it.” iii. 2014 State of DevOps Report – high performing organizations relied more on peer review and less on external approval

The DevOps Handbook – Part 3 The First Way – The Technical Practices of Flow 1. Introduction a. Goal – Enable & sustain fast flow of work by implementing continuous delivery i. Create the foundation configuration files 8. This also includes pre-production and build processes 9. Tools iv. 2014 State of DevOps Report – use of version control by Ops was the highest predictor of both IT performance & organizational created from trunk using a one-click process, and validated with automated tests.” v. 2015 State of DevOps Report – trunk-based development predicts higher throughput and better stability, and even higher

DevOps A Horse’s Perspective Just a horse, not a unicorn, 1000 deploys per/second not feasible.  History – How I Got Here?  Contentious relationship existed between development and operations.  Community of Practice, etc.  Test Driven Infrastructure  Blue – green deployments  Combining DevOps Scrum – planning, standups, boards, and backlogs  Making work visible (it’s still hidden)  Poor and Deployment Automation, Jez Humble and David Farley  The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win, Gene Kim, Kevin Behr, and George Spafford.  The Lean Primer, Craig

The DevOps Handbook – Part 1 & 2 1. Preface xi a. Myth—DevOps is Only for Startups: b. Myth—DevOps Replaces Agile c. Myth—DevOps is incompatible with ITIL d. Myth—DevOps is Incompatible with Information Security and Compliance: e. Myth—DevOps Means Eliminating IT Operations, or “NoOps” f. Myth—DevOps is Just “Infrastructure as Code” or Automation: g. Myth—DevOps is Only for Open Source Software: 2. Foreword xix 3. Imagine a World Where Dev and Ops Become DevOps: a. THE CORE, CHRONIC CONFLICT i. Among them are the two following goals, which must be pursued simultaneously: 1. Respond to the
