本文介绍了Gitlab CI CD，属于Gitlab的官方文档 https://about.gitlab.com/product/continuous-integration/

文中涉及到几个概念Gitlab CI，Gitlab CD，GitLab Runner，Pipelines

Gitlab CI

What is CI?
Continuous Integration is the practice of integrating code into a shared repository and building/testing each change automatically, as early as possible - usually several times a day.

CI翻译为持续集成，是基于团队共享代码库，开发人员合并提交代码后，触发事先编写好的pinpine构建任务，对代码进行构建，测试的过程。

CI是基于共享代码库的代码集成实践，基于每一次的更改进行构建和测试，通常一天进行很多次。

What is CD?

Continuous Delivery adds that the software can be released to production at any time, often by automatically pushing changes to a staging system.

CD用于对稳定系统的推送，在任何时候，自动的可以发布到生产环境。
Continuous Deployment goes further and pushes changes to production automatically.

Why your team needs a CI/CD workflow

Continuous Integration
Detects errors as quickly as possible: fix problems while fresh in developers mind

更快更可能的检测到错误

Reduces integration problems: smaller problems are easier to digest
降低集成问题，小的问题容易被消化

Avoid compounding problems: allows teams to develop faster, with more confidence
忽略混合问题，允许团队更快，更信任的开发

Continuous Delivery

Ensures every change is releasable: test everything, including deployment, before calling it done
确保每次更改都是可发布的
Lowers risk of each release: makes releases “boring”
对于每一次发布是低风险的
Delivers value more frequently: reliable deployments mean more releases
更多的部署代表更多的版本
Tight customer feedback loops: fast and frequent customer feedback on changes
在变化中快速频繁的接受客户的反馈

What are the advantages of GitLab CI/CD?

Integrated: GitLab CI/CD is part of GitLab, enabling a single conversation from planning to deployment (and beyond)
GitLab CI/CD 是GitLab 的一部分
Open source: CI/CD is a part of both the open source GitLab Community Edition and the proprietary GitLab Enterprise Edition
社区版本和企业版本均是开源的
Easy to learn: See our Quick Start guide
Seamless: Part of the single GitLab application, with a single great user experience
Scalable: Tests run distributed on separate machines of which you can add as many as you want
Faster results: Each build can be split in multiple jobs that run in parallel on multiple machines
Optimized for delivery: multiple stages, manual deploy gates, [environments,]
(https://docs.gitlab.com/ee/ci/environments.html) and variables

GitLab is one application for the entire DevOps lifecycle

GitLab是整个DevOps生命周期的一部分

Build your application using GitLab Runners
构建
Run unit and integration tests to check if your code is valid
测试
Look at a live preview of your development branch with [Review Apps]
(https://about.gitlab.com/product/review-apps/)before merging into stable
在线预览
Deploy to multiple environments like staging and production, and support advanced features such as canary deployments
基于不同环境的部署
Monitor performances and status of your application

Architecture

GitLab CI/CD

GitLab CI/CD is a part of GitLab, a web application with an API that stores its state in a database. It manages projects/builds and provides a nice user interface, besides all the features of GitLab.
