Simple Python CI/CD Pipeline

CI/CD pipeline menggunakan Jenkins dan Docker untuk build, test, dan deliver aplikasi Python dengan PyInstaller.

Prerequisites

• Docker & Docker Compose
• Git

Menjalankan

1. Setup Environment

# Generate .env dengan Docker GID dari host
echo "DOCKER_GID=$(getent group docker | cut -d: -f3)" > .env

2. Build & Start Containers

docker compose build --no-cache
docker compose up -d

3. Setup Jenkins

# Dapatkan admin password
docker exec jenkins cat /var/jenkins_home/secrets/initialAdminPassword

Akses Jenkins:

• Via NGINX: http://localhost:9000
• Direct: http://localhost:49000

1. Install suggested plugins
2. Buat admin user
3. Buat akun dicoding (Setup → Security → Allow users to sign up)

4. Buat Pipeline

1. Login sebagai dicoding
2. New Item → Pipeline → Pipeline script from SCM
3. SCM: Git, repo URL Anda, branch */master
4. Script Path: Jenkinsfile
5. Build Triggers: Poll SCM → H/2 * * * *
6. Install plugin Blue Ocean (opsional)

Pipeline Stages

1. Build — Build aplikasi dengan PyInstaller di dalam container python:3.9-slim
2. Test — Jalankan pytest pada sources/test_calc.py
3. Deliver — Archive artifacts (log.txt dan dist/*)
