Apa iku CI/CD pipeline lan tahapan-tahapanipun?

Question

Accepted Answer

A **CI/CD pipeline** is an **automated sequence of stages** that code passes through — from commit to deployment — typically including build, test, and deploy steps. It defines the automated path that turns a code change into a deployed release.

## Konsep pipeline

```text
A PIPELINE is an automated workflow of STAGES that run in sequence on each code change:
  → triggered by an event (a push, a PR, a merge, a schedule)
  → each stage runs automatically; if a stage FAILS, the pipeline STOPS (broken code
    doesn't proceed to later stages or production)
  → provides automation, consistency, and fast feedback
```

## Tahapan pipeline sing tipikak

```text
1. SOURCE   → triggered by a code change (checkout the code)
2. BUILD    → compile the code, install dependencies, build artifacts/images
3. TEST     → run automated tests (unit, integration), linting, static analysis
4. (SECURITY) → security scans (dependencies, code, container images)
5. PACKAGE  → create deployable artifacts (e.g. a Docker image pushed to a registry)
6. DEPLOY to STAGING → deploy to a test/staging environment; run further tests (e2e)
7. DEPLOY to PRODUCTION → release to production (manual approval for delivery, or
   automatic for deployment)
→ Each stage gates the next: failures stop the pipeline (quality gates).
```

## Karakteristik penting

```text
✓ AUTOMATED — runs without manual steps (except approvals if configured)
✓ FAIL FAST — a failing stage stops progression (don't deploy broken code)
✓ STAGES as quality GATES — code must pass each to advance
✓ Consistent and repeatable — the same process every time
✓ FAST FEEDBACK — developers learn quickly if their change passed/failed
```

## Ngapa iki penting

Pamahaman babagan CI/CD pipeline lan tahapan-tahapanipun minangka pengetahuan fundamental kanggo CI/CD, mula iku wigati banget minangka pengetahuan praktis kanggo modern software delivery.

A pipeline iku **automated sequence of stages** sing ngowahi code change dadi deployed release — mekanisme konkrit sing nglaksanakake CI/CD.

Pamahaman babagan **konsep pipeline** (automated workflow sing diuwak dening code changes, nglakoni stages kanthi urutan, mandheg menawa ana sing gagal supaya broken code ora lanjut) iku ide inti.

Pamahaman babagan **tahapan sing tipikak** — source (checkout), build (compile, dependencies, artifacts), test (automated tests, linting, static analysis), security scans, package (nggawe deployable artifacts kaya Docker images), deploy menyang staging (karo testing lanjutan), lan deploy menyang production (kanthi manual utawa automatic) — menehi struktur praktis babagan carane code mili saka commit menyang release.

Model berbasis tahapan iki, ing mana **saben tahapan dadi quality gate** (code kudu lulus kanggo lanjut, lan kegagalan mandheg kemajuan), iku sing njamin yen code sing verified lan bisa dadi uji coba wae sing tekan production — inti saka carane CI/CD ngaturake quality lan reliability.

Pamahaman babagan **karakteristik penting** (automation, fail-fast behavior, stages minangka quality gates, consistency, lan fast feedback) nukis ngapa pipelines efektif: dheweke ngganti proses manual, inconsistent karo automated, reliable path sing nangkep masalah awal lan deploy kanthi konsisten.

Amarga pipeline iku mekanisme sentral saka CI/CD (automated path sing nglaksanakake build, test, lan deploy karo quality gates), lan amarga pamahaman konsep, tahapan, lan karakteristikipun fundamental kanggo ngerti lan ngerjake CI/CD, pamahaman babagan CI/CD pipeline lan tahapan-tahapanipun iku wigati, pengetahuan praktis-relevan kanggo modern software delivery — struktur konkrit sing ngowahi filosofi CI/CD dadi automated reality, lan pengetahuan inti kanggo sapa wae sing ngerjake automated software delivery.
