GitLab 2 小时前 0 0

GitLab可以与各种外部服务集成，扩展其功能。本文将介绍常见的集成场景和配置方法。

Jira集成

# 配置Jira集成
# Project > Settings > Integrations > Jira

Web URL: https://your-company.atlassian.net
Username or Email: your-email@company.com
Password or API token: your-api-token
Project keys: PROJ, DEV

# 功能
- 在提交信息中引用Jira Issue: git commit -m "PROJ-123 Fix bug"
- 自动在Jira中添加评论
- 在MR中显示Jira Issue信息
- 自动转换Jira Issue状态

# 提交信息示例
git commit -m "PROJ-123 修复登录问题"

# GitLab会自动链接到Jira Issue
# https://your-company.atlassian.net/browse/PROJ-123

Slack集成

# 配置Slack通知
# Project > Settings > Integrations > Slack notifications

Webhook: https://hooks.slack.com/services/T00/B00/XXXX
Username: GitLab
Channel: #devops

# 触发事件
[x] Push
[x] Merge request
[x] Pipeline
[x] Issue
[x] Deployment

# Slack消息示例

└─────────────────────────────────────────────────────────────┘

# 使用Slack App (更多功能)
# 安装GitLab Slack App
# https://gitlab.com/gitlab-org/gitlab/-/integrations/slack/

钉钉/企业微信集成

# 使用Webhook发送到钉钉
# Project > Settings > Webhooks

URL: https://oapi.dingtalk.com/robot/send?access_token=xxx

# 或创建中间服务转换消息格式
# webhook-proxy.js
const express = require('express');
const axios = require('axios');
const app = express();

app.use(express.json());

const DINGTALK_WEBHOOK = 'https://oapi.dingtalk.com/robot/send?access_token=xxx';

app.post('/gitlab-webhook', async (req, res) => {
  const event = req.headers['x-gitlab-event'];
  const data = req.body;
  
  let message = '';
  
  if (event === 'Push Hook') {
    message = `### 📦 代码推送\n- 项目: ${data.project.name}\n- 分支: ${data.ref}\n- 提交者: ${data.user_name}`;
  } else if (event === 'Pipeline Hook') {
    const emoji = data.object_attributes.status === 'success' ? '✅' : '❌';
    message = `### ${emoji} Pipeline ${data.object_attributes.status}\n- 项目: ${data.project.name}\n- 分支: ${data.object_attributes.ref}`;
  }
  
  await axios.post(DINGTALK_WEBHOOK, {
    msgtype: 'markdown',
    markdown: {
      title: 'GitLab通知',
      text: message
    }
  });
  
  res.status(200).send('OK');
});

app.listen(3000);

Prometheus集成

# GitLab可以集成Prometheus监控
# Project > Settings > Integrations > Prometheus

API URL: http://prometheus.example.com:9090

# 或使用GitLab内置Prometheus
# /etc/gitlab/gitlab.rb
prometheus['enable'] = true
prometheus['listen_address'] = '0.0.0.0:9090'

# 启用环境监控
# 在项目CI/CD中配置
deploy:
  script:
    - ./deploy.sh
  environment:
    name: production
    url: https://myapp.example.com
    kubernetes:
      namespace: production

# 查看监控
# Project > Monitor > Metrics
# 显示应用指标、响应时间、错误率等

LDAP/AD集成

# /etc/gitlab/gitlab.rb

gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = {
  'main' => {
    'label' => 'Company LDAP',
    'host' => 'ldap.company.com',
    'port' => 389,
    'uid' => 'sAMAccountName',

      'name' => 'displayName',
      'first_name' => 'givenName',
      'last_name' => 'sn'
    }
  }
}

# 应用配置
sudo gitlab-ctl reconfigure
