# GitLab Continuous Integration (GitLab CI/CD)
|
||||
|
||||
GitLab provides tools for continuously integrating and delivering code.
|
||||
|
||||
Within the [entire DevOps lifecycle](../README.md#the-entire-devops-lifecycle), GitLab CI/CD spans
|
||||
the [Verify (CI)](../README.md#verify) and [Release (CD)](../README.md#release) stages.
|
||||
|
||||
## Overview
|
||||
|
||||
CI/CD is a vast area, so GitLab provides documentation for all levels of expertise. Consult the following table to find the right documentation for you:

## Introduction
|
||||
|
||||
The following introduces the process of continuous integration (CI) and continuous delivery (CD):
|
||||
|
||||
![Pipeline graph](img/cicd_pipeline_infograph.png)
|
||||
|
||||
The benefits of Continuous Integration are huge when automation plays an
|
||||
integral part of your workflow. GitLab comes with built-in Continuous
|
||||
Integration, Continuous Deployment, and Continuous Delivery support
|
||||
to build, test, and deploy your application.
|
||||
In this illustration:
|
||||
|
||||
Here's some info we've gathered to get you started.
|
||||
- New code is combined with existing code through a commit to a project's [repository](../user/project/repository/index.md).
|
||||
- The newly combined code is sent to a CI [pipeline](pipelines.md) where:
|
||||
- The code is [built](../user/project/pipelines/job_artifacts.md).
|
||||
- Unit and integration tests are run over the built code.
|
||||
- Assuming the build and tests are successful, a CD pipeline is triggered to allow for:
|
||||
- Review using [Review Apps](review_apps/index.md).
|
||||
- Deploying to configured [environments](environments.md).
|
||||
|
||||
## Getting started
|
||||
The benefits of CI/CD are vast, allowing automation to be an integral part of your workflow for testing, building, deploying, and monitoring your code.
|
||||
|
||||
The first steps towards your GitLab CI/CD journey.
|
||||
Because CI and CD with GitLab is broad topic with many possibilities, the rest of this section provides
|
||||
links to topics and resources needed to make use of GitLab CI/CD.
|
||||
|
||||
- [Getting started with GitLab CI/CD](quick_start/README.md): understand how GitLab CI/CD works.
|
||||
- [GitLab CI/CD configuration file: `.gitlab-ci.yml`](yaml/README.md) - Learn all about the ins and outs of `.gitlab-ci.yml`.
|
||||
- [Pipelines and jobs](pipelines.md): configure your GitLab CI/CD pipelines to build, test, and deploy your application.
|
||||
- Runners: The [GitLab Runner](https://docs.gitlab.com/runner/) is responsible by running the jobs in your CI/CD pipeline. On GitLab.com, Shared Runners are enabled by default, so
|
||||
you don't need to set up anything to start to use them with GitLab CI/CD.
|
||||
## Essentials
|
||||
|
||||
### Introduction to GitLab CI/CD

|
||||
## Special configuration (GitLab admin)
|
||||
- An [entire GitLab instance](../user/admin_area/settings/continuous_integration.md).
|
||||
- Specific projects, using [pipelines settings](../user/project/pipelines/settings.md).
|
