docker安装gitlab-runner

提示

理想情况下，不应将GitLab Runner与GitLab安装在同一台机器上。

安装

docker pull gitlab/gitlab-runner

docker run -itd --name gitlab-runner \
    --restart always \
    -v /srv/gitlab-runner/etc:/etc/gitlab-runner \
    -v /var/run/docker.sock:/var/run/docker.sock \
    gitlab/gitlab-runner

docker-compose

安装docker-compose
```
# unbuntu
apt install docker-compose
```

创建docker-compose.yml文件

version: '3.3'

services:
  gitlab-runner:
    network_mode: bridge # do not create new network
    image: 'gitlab/gitlab-runner'
    container_name: gitlab-runner
    restart: always
    volumes:
      - /srv/gitlab-runner/etc:/etc/gitlab-runner
      - /var/run/docker.sock:/var/run/docker.sock

确保与docker-compose.yml文件在同一目录下并启动它
```
docker compose up -d
```

注册gitlab-runner

一个Runner可以特定于某个项目，也可以在GitLab CI中服务于任何项目。服务于所有项目的Runner称为Shared Runner

获取令牌

Shared Runner Admin Area> Overview > Runners
Group Runner Group > CI/CD > Runners
Specific Runners Project > Settings > CI/CD > Runners > Specific runners

如果你是GitLab实例管理员的话，你可以注册一个Shared Runner

Register

进入容器执行注册命令

docker exec -it gitlab-runner gitlab-runner register

接下来会依次要求输入以下信息

Enter the GitLab instance URL (for example, https://gitlab.com/):
http://192.168.37.128/

Enter the registration token:
2uHJuR-A8c97bvc2yAxh

Enter a description for the runner:
[f0f33d68c59a]: docker-runner

Enter tags for the runner (comma-separated):
v1

Registering runner... succeeded                     runner=x8b5fALJ
Enter an executor: virtualbox, docker+machine, kubernetes, custom, docker, docker-ssh, parallels, shell, ssh, docker-ssh+machine:
docker

Enter the default Docker image (for example, ruby:2.6):
alpine:latest

Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

以上是通过手动一步一步设置，这种操作相对比较麻烦一些，下面我们根据参数指定注册过程需要的数据直接配置，参数根据需要自行修改

gitlab-runner register \
  --non-interactive \
  --url "http://192.168.37.128/" \
  --registration-token "2uHJuR-A8c97bvc2yAxh" \
  --executor "docker" \
  --docker-image alpine:latest \
  --description "docker-runner" \
  --maintenance-note "Free-form maintainer notes about this runner" \
  --tag-list "docker,aws" \
  --run-untagged="true" \
  --locked="false" \
  --access-level="not_protected"

如果是在Docker容器中运行的runner，注册命令的结构还可以类似于这样

docker run -itd --name gitlab-runner \
  --restart always \
  -v /srv/gitlab-runner/etc:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  gitlab/gitlab-runner register \
  --non-interactive \
  --executor "docker" \
  --docker-image alpine:latest \
  --url "http://192.168.37.128/" \
  --registration-token "2uHJuR-A8c97bvc2yAxh" \
  --description "docker-runner" \
  --maintenance-note "Free-form maintainer notes about this runner" \
  --tag-list "docker,aws" \
  --run-untagged="true" \
  --locked="false" \
  --access-level="not_protected"

docker in docker

gitlab-runner register -n \
   --url http://192.168.37.128/ \
   --registration-token GR1348941YfXHiANyYGSk7a6SzsiK \
   --executor docker \
   --description "My Docker Runner" \
   --docker-image "alpine:latest" \
   --docker-privileged

docker套接字绑定

gitlab-runner register \
   --url http://192.168.37.128/ \
   --registration-token GR1348941YfXHiANyYGSk7a6SzsiK \
   --executor docker \
   --description "My Docker Runner" \
   --docker-image "docker:latest" \
   --docker-volumes /var/run/docker.sock:/var/run/docker.sock

到这里就注册成功了，我们可以在gitlab的Runners界面看到增加了一个runner
