## 1. Apa unit terkecil yang dapat dideploy di Kubernetes?

**Jawaban**

Pod adalah unit terkecil yang dapat dideploy di Kubernetes. Sebuah Pod merepresentasikan satu atau lebih container yang berbagi jaringan dan storage yang sama. Pod merupakan blok dasar tempat semua abstraksi Kubernetes lainnya seperti Deployments, ReplicaSets, dan Services dibangun.

## 2. Komponen Kubernetes mana yang bertanggung jawab untuk mempertahankan jumlah replika Pod yang ditentukan tetap berjalan?

**Jawaban**

Deployment mengelola ReplicaSets yang mempertahankan jumlah Pod yang diinginkan tetap berjalan. Deployment menyediakan kemampuan rolling update, rollback, dan scaling. Deployment adalah cara yang direkomendasikan untuk mendeploy aplikasi stateless di Kubernetes.

## 3. Perintah kubectl mana yang menampilkan semua Pod di semua namespace?

**Jawaban**

Perintah kubectl get pods --all-namespaces (atau -A sebagai singkatan) menampilkan semua Pod dari semua namespace. Secara default, kubectl beroperasi di namespace default. Flag --all-namespaces memungkinkan untuk melihat resource sistem di kube-system serta yang ada di namespace lain.
