岗位职责（运维是干什么、产出什么）和关键指标（度量产出成果）


关键指标，不仅仅包含服务可用性，还有比如服务器资源达标率、服务故障数据（故障分类、故障响应时间、平均故障恢复时间、故障告警覆盖率）、服务安全指标、服务资源到位时长等等。


业务的成功是第一要务



最常做的变更是二进制、配置的变更，当然，还有对基础环境以及组件的变更需求。

定义故障 -> 响应故障 -> 快速定位 -> 快速止损

牵头整体的稳定性建设，各个业务需要出接口人极力配合，所谓的稳定性建设，包括事前的预防风控、事中的统筹协同、事后的复盘推进，这也是 SRE 对公司的最大价值。





对象管理是纵向模式，围绕运维对象、建设生命周期的管理平台。

场景管理是横向模式，根据运维场景、纳管多种运维对象的生命周期阶段。运维场景的分类，包括交付/变更、监控/度量、多云、成本等等，非常贴近业务研发的工作习惯、覆盖少数高频场景


  • 先保障稳定，然后再优化
  • 提供可靠的测试依据和时间验证
  • 使用可控的自动化手段提升效率
  • 保持简单，监控一切
  • 面向预算的运维
  • 面向场景的智能运维 - 智能运维就是需要深入理解业务，合理配置资源和架构来满足不同业务场景的需求
  • 持续集成和发布系统

  • 一、 以可配置为荣，以硬编码为耻

  • 二、 以互备为荣，以单点为耻

  • 三、 以随时重启为荣，以不能迁移为耻

  • 四、 以整体交付为荣，以部分交付为耻

  • 五、 以无状态为荣，以有状态为耻

  • 六、以标准化为荣，以特殊化为耻

  • 七、以自动化工具为荣，以手动和人肉为耻

  • 八、以无人值守为荣，以人工介入为耻



关注公司的业务现在急需什么？公司最核心的用户他们需要什么？他们需要什么我们就优先做什么，

Docker Container mount to a mysteric folder which I don't know where is it.

Env:  Ubuntu 20.04  When install too many versions of docker on the same machine,  it could have a weird mount behavior. I have a folder called /media/xxx/uuid/prod/db, hereafter, "local db folder".   and I mount this folder to the /db folder inside container, hereafter "container db folder".    I start container like this:  docker run --rm --mount type=bind,source=/media/xxx/uuid/prod/db,target=/db image:latest As you can expected, something happened. the container was  up and running.  the mount seemed not right. If I add a new file to the local db folder , the new file was not available in container db folder ,  and vice versa,  if I add a new file to the container db folder ,  the file wasn't available in the local db folder either.   Looks like the local db folder and container db folder wasn't mapped.   Run docker inspect, I could see the mount configure was correct, from  /media/xxx/uuid/prod/db to /db However, if I stopped the container, and create

[读书笔记] - 3-rhetorical-techniques-to-increase-your-impact

https://hbr.org/2023/03/3-rhetorical-techniques-to-increase-your-impact Turn "to" to "to be",   Turn "Don't" to "Don't to be" Turning actions (i.e., helping or voting) into identities (i.e., being a helper or voter) makes people more likely to take action because it turns that action into an opportunity to claim a desired identity.     speak with a great deal of certainty.   --   They say that answers are  unambiguous , results are  guaranteed , and a certain course of action will  definitely   work.  Qualifying statements make listeners less likely to follow our advice or adopt a recommended course of action.  Hedging hurts because it makes communicators seem less confident.   our research finds  that personal hedges (i.e., “it  seems to me  like this will work”) are more persuasive than   “it  seems  like this will work”,   because they convey confidence .    Whether online on social media, or offline in one-to-one conversations or meet
