satisfaction, and employee happiness 2. one of the best predictors of short lead times was small batch sizes of work b. Agile, Continuous Delivery, and the Three Ways 7 c. The First Way: The Principles context of global goals. ii. REDUCE BATCH SIZES1. Another key component to creating smooth and fast flow is performing work in small batch sizes. 2. Large batch sizes result in skyrocketing levels of Development has worked on is released to production deployment. Like in manufacturing, this large batch release creates sudden, high levels of WIP and massive disruptions to all downstream work centers

A FAST AND RELIABLE AUTOMATED VALIDATION TEST SUITE i. Slow and periodic feedback kills – larger batch sizes compound effort needed to identify causes ii. Unit tests – test a single method, class, or costs, 140% increase in programs under development, 78% reduction in cost per program c. SMALL BATCH DEVELOPMENT AND WHAT HAPPENS WHEN WE COMMIT CODE TO TRUNK INFREQUENTLY i. Branching Strategies TRUNK-BASED DEVELOPMENT PRACTICES i. CI and Trunk-based development (TBD) are countermeasures to large batch size ii. TBD enables: 1. Frequent commits 2. Runs of automated tests of the integrated system

pod控制器是由kube-controller-manager组件提供的一些资源，负责控制pod的创 建、删除、重新调度、运行时间等。常用的pod控制器有ReplicaSet, Deployment, DaemonSet, Job, CronJob等，如果pod被删除，则可以重新拉起一个 ★通过kind: Pod创建的容器组，在kubectl delete pod xxx时，它就真的被删除 了，不会重新拉起一个新的pod，建议使用pod控制器去创建pod #查看 ★Job控制器 job控制器用于运行一次性pod（如执行sql脚本或一次性备份任务等）容器中的 进程在正常运行结束后，置为completed状态，且不会再重启，如果进程运行失 败，则根据配置决定是否要重启 # vi xx-job.yml #内容如下 apiVersion: batch/v1 kind: Job metadata: name: name: myjob #Job名 spec: comple�ons: 3 #一共起1个pod（默认1） parallelism: 2 #可同时运行的pod数（默认1） template: spec: containers: #定义一组容器 - name: jobxx #容器名，小写字母开头，后可接数字-减号，不可带小数点

deployment process 2. Increase friction by adding more steps/approvals which tends to increase batch size ii. Toyota Production System – “people closest to a problem typically know the most about it help improve overall quality, provide cross-training, learning, and skill improvements. iii. Keep batch sizes of reviews small iv. 4 simple Peer Review Guidelines 1. Everyone must have someone review project and/or manual 1. Manual testing is slower and more tedious 2. Tends towards increasing batch sizes ii. Fully integrate testing into daily work – enable flow, more automated testing h. ENABLE

powerful integrated development environment (IDE) that centralizes the tools that help him or her do the job.  The code is built automatically using Continuous Integration, and it is tested automatically requirements, but instead on high-level objectives. Instead of telling the project team how to do its job, we might begin the project with a hypothesis of what will best accomplish the objectives, but then
