🎯 Goal: GitLab Otomatis Trigger Jenkins via Webhook Saat Push/Deploy

---

✅ Step-by-Step Integrasi GitLab ➝ Jenkins via Webhook

---

🔹 1. Buat Jenkins Job (Pipeline)

• Job harus bertipe Pipeline

• Gunakan Git sebagai Source Code Management

• Atur repo URL, misalnya:

  http://gitlab.local/widi/playwright.git
  

• Gunakan Jenkinsfile dari repo

---

🔹 2. Generate API Token di Jenkins (jika butuh security)

Kalau kamu pakai GitLab ➝ trigger Jenkins pakai URL, kamu bisa:

• Masuk ke Jenkins ➝ Manage Jenkins ➝ Manage Users ➝ klik user-mu ➝ Configure

• Buat API Token, simpan token itu

Contoh URL-nya nanti:

http://<jenkins_user>:<jenkins_token>@<jenkins_host>:<port>/job/<job_name>/build?token=<trigger_token>

---

🔹 3. Aktifkan Trigger Token di Jenkins Job

1. Masuk ke Jenkins Job ➝ Configure

2. Scroll ke bawah ➝ centang ✅ “Trigger builds remotely”

3. Masukkan Authentication Token misalnya: gitlab-trigger

4. Klik Save

📌 URL webhook-nya nanti jadi seperti ini:

http://jenkins.local:8080/job/playwright-from-gitlab/build?token=gitlab-trigger

---

🔹 4. Buka GitLab Project ➝ Settings ➝ Webhooks

1. Masuk ke project GitLab

2. Menu ➝ Settings ➝ Webhooks

3. Isi:

   • URL:

     http://jenkins.local:8080/job/playwright-from-gitlab/build?token=gitlab-trigger
     

   • ✅ Centang Push events

   • (opsional) Centang Merge Request events kalau mau trigger juga di MR

   • ✅ Enable SSL verification (jika pakai HTTPS)

4. Klik Add Webhook

---

🔹 5. (Opsional) Uji Webhook

Setelah ditambahkan, klik tombol "Test" ➝ Push event
➡ Pastikan Jenkins job langsung jalan.

---

🔹 6. (Opsional) Tambahkan GitLab Credentials ke Jenkins (Kalau pakai private repo)

Masuk ke Jenkins:

• Manage Jenkins ➝ Credentials ➝ tambahkan:

  • Username/password atau SSH key GitLab

---

✅ Rangkuman URL Webhook Format

http://jenkins_user:api_token@jenkins_host:8080/job/job_name/build?token=trigger_token

📌 Jika Jenkins di LAN dan tidak perlu otentikasi:

http://jenkins.local:8080/job/playwright-from-gitlab/build?token=gitlab-trigger

---

🚀 Ready to Go!

Setelah itu:

• Setiap ada push ke branch tertentu di GitLab

• Webhook ➝ trigger Jenkins

• Jenkins jalankan pipeline

• Playwright test jalan

• Report tampil 🎯
