搭建GitLab Runner（基于Docker）

前面的文章中已经介绍了搭建GitLab（基于Docker），直接在Ubuntu 20.04系统中搭建GitLab Runner

名称	服务器	搭载服务
A	192.168.1.72	GitLab（已搭建完成）
B	192.168.1.73	GitLab Runner（未搭建完成）

修改hosts

在B主机中修改hosts，增加一条192.168.1.72 gitlab.com。

$ cat /etc/hosts
127.0.0.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
192.168.1.72 gitlab.com

安装GitLab Runner镜像&启动GitLab Runner容器

由于我这里的gitlab是自定义域名，所有需要使用--add-host来向容器增加一条的hosts。

$ sudo docker run -d --name gitlab-runner \
    --add-host gitlab.com:192.168.1.72 \
    --restart always \
    -v /srv/gitlab-runner/config:/etc/gitlab-runner \
    -v /var/run/docker.sock:/var/run/docker.sock \
    gitlab/gitlab-runner:latest

注册Runner

在GitLab中，进入一个项目，点击Settings的CI/CD。
在这里插入图片描述

看到图中Specific runners下面有步骤，其中有Register the runner with this URL和And this registration token是注册中Runner的时候要输入的URL和Token。

注册命令如下：

$ sudo docker run --add-host gitlab.com:192.168.1.72 --rm -it -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register

输入参数

http://gitlab.com/
btrbkwsSwHbFZs54PJWd
cicd
cicd
docker
node:alpine

注册成功

$ sudo docker run --add-host gitlab.com:192.168.1.72 --rm -it -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=9 revision=58ba2b95 version=14.2.0
Running in system-mode.
Enter the GitLab instance URL (for example, https://gitlab.com/):
http://gitlab.com/
Enter the registration token:
btrbkwsSwHbFZs54PJWd
Enter a description for the runner:
[7c296633a3d5]: cicd
Enter tags for the runner (comma-separated):
cicd
Registering runner... succeeded                     runner=btrbkwsS
Enter an executor: custom, docker, shell, docker+machine, kubernetes, docker-ssh, parallels, ssh, virtualbox, docker-ssh+machine:
docker
Enter the default Docker image (for example, ruby:2.6):
node:alpine
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
