# Backup Kubernetes Cluster using Velero > Canonical: https://zufardhiyaulhaq.com/backup-kubernetes-cluster-using-velero/ > Tags: [kubernetes, tooling] Velero gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. Velero have ability to backup cluster, migrate cluster resource to other cluster, and also replicate cluster to other cluster. This is my first time trying Velero. correct me if I am wrong. ## Requirement - docker CLI - docker-compose CLI - velero CLI - minio (mc) CLI - virtualbox - minikube ### Setup Minio Minio running as storage backend for velero to store the backup, you can using other storage backend like AWS S3, GCP GCS, and other defined in [backend provider documentation](https://velero.io/docs/v1.4/supported-providers/). For simplicity, we use Minio. - Install Minio using docker-compose

version: '3.7'

services:
  minio:
    container_name: minio-storage
    image: minio/minio:RELEASE.2020-05-29T14-08-49Z
    volumes:
      - minio-storage:/minio-storage
    ports:
      - "9000:9000"
    environment:
      MINIO_ACCESS_KEY: zufar_minio_access_key
      MINIO_SECRET_KEY: zufar_minio_secret_key
    command: server /minio-storage
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

volumes:
  minio-storage:

docker-compose up -d

- get minio IP

export MINIO_IP=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' minio-storage)
echo "Minio IP: $MINIO_IP"

- create storage bucket You can create bucket from web dashboard or via CLI.

mc config host add minio-storage http://$MINIO_IP:9000 zufar_minio_access_key zufar_minio_secret_key
mc mb minio-storage/velero-bucket
mc policy set public minio-storage/velero-bucket

### Setup Kubernetes For simplicity, we using minikube to run Kubernetes cluster.

minikube start --driver=virtualbox --force=true --kubernetes-version='1.15.11' --memory 16128 --cpus 8 --profile cluster-velero

### Setup Velero Velero have two system, the client-side and server-side. First install the CLI (client-side) using brew or asdf or other. It is depended on your environment. Velero installation is a little complex, for now lets just use `velero install`. You must run this command from environment that have access directly to Kubernetes cluster (have kubectl working). - Add Velero credential

vi credentials-velero

[default]
aws_access_key_id = zufar_minio_access_key
aws_secret_access_key = zufar_minio_secret_key

- Install Velero in Kubernetes

velero install \
    --provider aws \
    --plugins velero/velero-plugin-for-aws:v1.0.0 \
    --bucket velero-bucket \
    --secret-file ./credentials-velero \
    --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://$MINIO_IP:9000 \
    --snapshot-location-config region=minio,s3ForcePathStyle="true",s3Url=http://$MINIO_IP:9000

- Make sure velero working

kubectl -n velero get pod
kubectl -n velero get VolumeSnapshotLocation
kubectl -n velero describe VolumeSnapshotLocation
kubectl -n velero get BackupStorageLocation
kubectl -n velero describe BackupStorageLocation

## Simulate disaster ### Without PVC - create namespace & deployment

kubectl apply -f https://gist.githubusercontent.com/zufardhiyaulhaq/c7d59b0725e6c23e5bf6daeeb82b3333/raw/778986f376c5aeef59ec528a1f3a510e0baaab7f/deployment-svc-kubernetes

kubectl -n nginx-example get pod
kubectl -n nginx-example get svc

- create namespace backup

velero backup create nginx-backup --include-namespaces nginx-example

- check backup progress

velero backup describe nginx-backup
velero backup logs nginx-backup

You can also check Minio bucket. - simulate disaster Please don't delete namespace in production cluster guys

kubectl delete namespace nginx-example

- Check namespace & deployment already deleted

kubectl get namespaces
kubectl -n nginx-example get pod
kubectl -n nginx-example get svc

- Restore namespaces

velero restore create --from-backup nginx-backup

- Check namespace & deployment already restored

kubectl get namespaces
kubectl -n nginx-example get pod
kubectl -n nginx-example get svc

### With PVC - delete previous namespace

kubectl delete namespace nginx-example

- create namespace & deployment

kubectl apply -f https://gist.githubusercontent.com/zufardhiyaulhaq/2ce21ca351807991d8a370315695faee/raw/4c0575f2c74aa26fe32f4eff555be3efcf15e23c/deployment-svc-kubernetes-pvc

kubectl -n nginx-example get pod
kubectl -n nginx-example get svc
kubectl -n nginx-example get pvc
