安裝 GitLab Runner 方式

Ubuntu 24.04

下載最新版本的 GitLab Runner

sudo curl -L --output /usr/local/bin/gitlab-runner "https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64"

賦予執行權限

sudo chmod +x /usr/local/bin/gitlab-runner

創建 GitLab Runner 用戶

sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

安裝並啟動服務

sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
sudo gitlab-runner start

驗證安裝
```
gitlab-runner --version
```

將 Runner 加入 GitLab

進入 GitLab Admin 介面 → CI/CD → Runner → Create Instance Runner
輸入 Tag Exp. docker , 勾選 Run untagged job

點下 Create Runner 後, 選 Platform Exp. Linux , 依據以下 Step1 的 CLI 到 Runner 主機執行 Exp.

gitlab-runner register  --url https://gitlab.ichiayi.com  --token glrt-7xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxKdToyCw.01.120st7l4l

等一下點選 Runner 如果沒問題就會出現剛剛建立的 Runner

設定可執行 Docker in Docker

因為 Kaniko 已經不再維護, 改用需要設定 Privileged 的 BuildKit

如果使用 BuildKit 沒有設定 Privileged 執行 docker build 時會出現類似以下的錯誤訊息

mount: permission denied (are you root?)
Could not mount /sys/kernel/security.
AppArmor detection and --privileged mode might break.

編輯 /etc/gitlab-runner/config.toml

:
[[runners]]
:
  executor = "docker"
:
  [runners.docker]
    tls_verify = false
    image = "docker:27-cli"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache", "/certs/client"]
    shm_size = 0
    network_mtu = 0

重新啟動 Runner
```
sudo systemctl restart gitlab-runner
```
查看 Runner 狀態
```
sudo gitlab-runner status
```
驗證配置
```
sudo gitlab-runner verify
```
