Apa iku GitOps?

Accepted Answer

**GitOps** minangka pendekatan kanggo continuous deployment (utamane kanggo Kubernetes) ing ngendi **Git minangka sumber kebenaran tunggal** kanggo kondisi sing dikarepake saka infrastruktur lan aplikasi, lan agent otomatis terus-terusan **ngrekonsilasi** kondisi nyata supaya cocog karo Git. Owah-owahan digawe liwat Git, lan sistem narik lan nerapake dheweke.

## Model GitOps

```text
Git holds the DESIRED STATE (declarative configs: Kubernetes manifests, Helm charts, etc.):
  → an AGENT in the cluster continuously COMPARES actual state vs Git (desired state)
  → it RECONCILES: automatically applies changes to make reality match Git
  → to deploy/change: commit to Git → the agent detects and applies it (PULL-based)
→ Git = single source of truth; the system continuously converges to it.
```

## Deployment push vs pull

```text
TRADITIONAL CI/CD (push) → the pipeline PUSHES changes TO the cluster (CI has cluster
  credentials, runs kubectl apply)
GITOPS (pull) → an agent INSIDE the cluster PULLS from Git and applies changes:
  ✓ cluster credentials stay IN the cluster (more secure — CI doesn't need them)
  ✓ continuous reconciliation (drift is auto-corrected)
→ Tools: ArgoCD, Flux (Kubernetes GitOps operators).
```

## Kauntungan

```text
✓ Git as SOURCE OF TRUTH — all changes via Git (versioned, reviewed, audited, history)
✓ DECLARATIVE — describe the desired state; the system makes it so (and KEEPS it so)
✓ AUTO-RECONCILIATION — drift (manual changes) is detected and corrected automatically
✓ Easy ROLLBACK — revert the Git commit → the system reverts to that state
✓ SECURITY — pull-based (no external system needs cluster credentials)
✓ Visibility — Git history = deployment history; clear audit trail
```

## Kenapa iki penting

Ngerteni GitOps minangka pengetahuan tingkat senior sing berharga amarga iki pendekatan continuous deployment sing penting lan saya-saya populer (utamane kanggo Kubernetes), dadi berguna kanggo delivery cloud-native modern.

Model GitOps inti — **Git minangka sumber kebenaran tunggal** kanggo kondisi sing dikarepake, karo **agent otomatis terus-terusan ngrekonsilasi** kondisi nyata supaya cocog karo Git — nampilake pendekatan sing bersih lan kuwat: sampeyan ngowah sistem kanthi nglakoni commit menyang Git, lan sistem narik lan nerapake owah-owahan, terus-terusan nggabung realitas menyang kondisi sing dikarepake sing dideklarasikake.

Ngerteni **pembedaan push vs pull** minangka kunci: CI/CD tradisional **mendorong** owah-owahan menyang kluster (mbutuhake CI kanggo nduweni kredensial kluster), dening GitOps nggunakake model **pull** ing ngendi agent ing kluster narik saka Git — sing luwih **aman** (kredensial kluster tetep ing kluster; ora ana sistem CI eksternal sing mbutuhake dheweke) lan nyedhiyakake **continuous reconciliation** (otomatis mbenerake drift).

Ngerteni **kauntungan** — Git minangka sumber kebenaran (kabeh owah-owahan versioned, ditinjau, diaudit liwat riwayat Git), model deklaratif (nerangake kondisi sing dikarepake lan nggawe sistem njaga dheweke), **automatic reconciliation** (ndeteksi lan mbenerake drift saka owah-owahan manual), **rollback** sing gampang (mbalik commit Git mbabali sistem), **security** sing ditingkatake (berbasis pull), lan **visibility** (riwayat Git minangka riwayat deployment) — nerangake kenapa GitOps menarik kanggo Kubernetes deployment.

Keneng tools (ArgoCD, Flux) nyedhiyakake konteks praktis.

GitOps saya-saya diadopsi kanggo delivery berbasis cloud-native lan Kubernetes, nampilake evolusi modern saka praktek CD.

Samantara GitOps minangka pendekatan continuous deployment sing penting lan berkembang (karo kauntungan nyata ing security, auditability, drift correction, lan rollback) utamane kanggo Kubernetes, lan samantara ngerteni modelé, pendekatan berbasis pull, lan kauntungané minangka berharga kanggo delivery modern, ngerteni GitOps minangka pengetahuan tingkat senior sing berharga kanggo continuous deployment cloud-native — paradigma CD modern, CD sing saya-saya relevan nampilake evolusi saka praktek deployment, berguna kanggo tim sing ngadopsi Kubernetes lan operasi deklaratif berbasis Git.
