Gitlab Runner安装和简单使用
Gitlab Runner安装和简单使用
1. 安装和配置
-
GitLab-CI
GitLab-CI就是一套配合GitLab使用的持续集成系统（当然，还有其它的持续集成系统，同样可以配合GitLab使用，比如Jenkins）。而且GitLab8.0以后的版本是默认集成了GitLab-CI并且默认启用的。
-
GitLab-Runner
GitLab-Runner是配合GitLab-CI进行使用的。一般地，GitLab里面的每一个工程都会定义一个属于这个工程的软件集成脚本，用来自动化地完成一些软件集成工作。当这个工程的仓库代码发生变动时，比如有人push了代码，GitLab就会将这个变动通知GitLab-CI。这时GitLab-CI会找出与这个工程相关联的Runner，并通知这些Runner把代码更新到本地并执行预定义好的执行脚本。
所以，GitLab-Runner就是一个用来执行软件集成脚本的东西。你可以想象一下：Runner就像一个个的工人，而GitLab-CI就是这些工人的一个管理中心，所有工人都要在GitLab-CI里面登记注册，并且表明自己是为哪个工程服务的。当相应的工程发生变化时，GitLab-CI就会通知相应的工人执行软件集成脚本。如下图所示：
-
Runner类型
GitLab-Runner可以分类两种类型：Shared Runner（共享型）和Specific Runner（指定型）。
Shared Runner：这种Runner是所有工程都能够用的。只有系统管理员能够创建Shared Runner。
Specific Runner：这种Runner只能为指定的工程服务。拥有该工程访问权限的人都能够为该工程创建Shared Runner。 -

其中有一个步骤要输入项目的token。
配置完成后，runners里面会出现刚才配置的选项：
2. 使用
项目根目录添加文件：.gitlab-ci.yml
内容如下：
stages:
- dev
dev-job:
stage: dev
tags:
- dev
only:
- master
script:
- echo 'hello runner'
提交后，会自动触发部署脚本
