What is Kubernetes Helm?

Question

Accepted Answer

**Helm** — package manager for Kubernetes (charts = deployable units).

```bash
# Install Helm
curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

# Add repository
helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

# Search charts
helm search repo nginx

# Install chart
helm install my-release bitnami/nginx \
  --set service.type=ClusterIP \
  --namespace production

# Upgrade release
helm upgrade my-release bitnami/nginx --set replicaCount=3

# List releases
helm list -A

# Rollback
helm rollback my-release 1

# Uninstall
helm uninstall my-release
```

**Chart structure:**
- Chart.yaml: metadata.
- values.yaml: default configuration.
- templates/: Kubernetes manifests.
