DevOps

Introduction

A good talk about DevOps https://theagileadmin.com/what-is-devops/

DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.

Better methods/tools are developed every once in a while. Keep Learning, Keep Fighting.

為了確保部署軟體的功能一致，「持續部署」必須採用同一個包裝好的套件(package)， To make sure the consistance, same package must be used during the CD process.

Configuraiton Externalization: DO NOT configure settings by hard-coded 另一個達到「持續部署」的重要手段是要針對軟體可以客制化的功能，將其組態/設定外部化(configuraiton externalization)，簡單點講：就是不要將設定(settings)寫死(hard-coded)在程式碼裡面。
