Velero

Velero (formerly Heptio Ark) gives you tool to back up and restore your Kubernetes cluster resources and persistent volumes. You can run Velero with a cloud provider or on-premises. Velero lets you:

  • Take backups of your cluster and restore in case of loss.
  • Migrate cluster resources to other clusters.
  • Replicate your production cluster to development and testing clusters.

Velero consists of:

  • A server that runs on your cluster
  • A command-line client that runs locally

Requirements​

Velero requires to have already deployed the prometheus-operator CRDs as this feature deploys a ServiceMonitor definition. It can be deployed using the fury-kubernetes-monitoring KFD core module.

Server deployment​

Every velero deployment, does not matter if on-premises or in any of the supported cloud, can configure schedules to back up all cluster manifests and/or cluster persistence volumes.

Velero on-premises​

The velero-on-prem feature deploys a MinIO instance in the same cluster as object storage backend that Velero can use to store backup data.

Example kustomization.yaml file

namespace: kube-system

bases:
  - katalog/velero/velero-on-prem

Velero on AWS​

The AWS deployment alternative requires to have created cloud-credentials secret in the kube-system namespace. You can find a terraform module designed to create all necessary cloud resources to make velero works in AWS.

You can find and example terraform project using the aws-velero terraform module here

$ cd example/aws-example
$ terraform init
# omitted output
$ terraform apply --var="my_cluster_name=kubernetes-cluster-and-velero"
# omitted output
$ terraform output -raw cloud_credentials > /tmp/cloud_credentials.config
$ terraform output -raw volume_snapshot_location > /tmp/volume_snapshot_location.yaml
$ terraform output -raw backup_storage_location > /tmp/backup_storage_location.yaml
$ kubectl apply -f /tmp/cloud_credentials.config -n kube-system
# omitted output
$ kubectl apply -f /tmp/volume_snapshot_location.yaml -n kube-system
# omitted output
$ kubectl apply -f /tmp/backup_storage_location.yaml -n kube-system
# omitted output

Then, you will be able to deploy the velero AWS deployment.

Example kustomization.yaml file

namespace: kube-system

bases:
  - katalog/velero/velero-aws

Velero on GCP​

The GCP deployment alternative requires to have created cloud-credentials secret in the kube-system namespace. You can find a terraform module designed to create all necessary cloud resources to make velero works in GCP.

Then, you will be able to deploy the velero GCP deployment.

Example kustomization.yaml file

namespace: kube-system

bases:
  - katalog/velero/velero-gcp

Velero on Azure​

The Azure deployment alternative requires to have created cloud-credentials secret in the kube-system namespace. You can find a terraform module designed to create all necessary cloud resources to make velero works in Azure.

Then, you will be able to deploy the velero Azure deployment.

Example kustomization.yaml file

namespace: kube-system

bases:
  - katalog/velero/velero-azure

Velero Restic​

Velero has support for backing up and restoring Kubernetes volumes using a free open-source backup tool called restic.

velero-restic requires to have a velero deployment running in the cluster before deploy it. Velero restic is not tied to be deployed on prem or on cloud. So feel free to deploy it with your prefered velero deployment.

namespace: kube-system

bases:
  - katalog/velero/velero-aws
  - katalog/velero/velero-restic

Velero schedule​

This module contains a couple of useful velero schedules to perform automatic backups of cluster manifests and/or persistence volumes.

Feel free to deploy these schedules if fits in your business:

namespace: kube-system

bases:
  - katalog/velero/velero-aws
  - katalog/velero/velero-schedules
