Kubernetes Fury DR

Kubernetes Fury Disaster Recovery (DR) implements backups and disaster recovery for the Kubernetes Fury Distribution (KFD) using Velero.

If you are new to KFD please refer to the official documentation on how to get started with KFD.

Overview

Kubernetes Fury DR module is based on Velero and Velero Node Agent.

Velero allows you to:

backup your cluster
restore your cluster in case of problems
migrate cluster resources to other clusters
replicate your production environment to development and testing environment.

Together with Velero, Velero Node Agent allows you to:

backup Kubernetes volumes
restore Kubernetes volumes

The module contains also velero plugins to natively integrate with Velero with different cloud providers and use cloud provider's volumes as the storage backend.

Packages

Kubernetes Fury DR provides the following packages:

Package	Version	Description
velero	`1.13.0`	Backup and restore, perform disaster recovery, and migrate Kubernetes cluster resources and persistent volumes.

The velero package contains the following additional components:

Component	Description
velero-node-agent	Incremental backup and restore of Kubernetes volumes.
velero-schedules	Common schedules for backup

Integration with cloud providers

Use the following Velero Plugins to integrate Velero with cloud providers:

Plugin	Description
velero-aws	Plugins to support running Velero on AWS
velero-gcp	Plugins to support running Velero on GCP
velero-azure	Plugins to support running Velero on Azure

Deploy the necessary infrastructure to persist the backups natively in cloud providers volumes, using the following terraform modules:

Terraform Module	Description
aws-velero	Creates AWS resources and Kubernetes CRDs to persist backups.
azure-velero	Creates Azure resources and Kubernetes CRDs to persist backups.
gcp-velero	Creates GCP resources and Kubernetes CRDs to persist backups.

Velero on AWS

Velero on AWS is based on the AWS Velero Plugin.

It requires the secret cloud-credentials in the kube-system namespace containing a service account with appropriate credentials. As an alternative, the module supports authentication via IAM Roles.

To deploy Velero on AWS:

List the packages you want to deploy and their version in a Furyfile.yml

bases:
  - name: dr/velero/velero-aws
    version: "v2.3.0"
  - name: dr/velero/velero-node-agent
    version: "v2.3.0"
  - name: dr/velero/velero-schedules
    version: "v2.3.0"

modules:
  - name: dr/aws-velero
    version: "v2.3.0"

See furyctl documentation for additional details about Furyfile.yml format.

Execute furyctl legacy vendor -H to download the packages
Inspect the downloaded packages under ./vendor/katalog/velero.
Deploy the necessary infrastructure via terraform using the aws-velero terraform module:

module "velero" {
  source             = "path/to/vendor/modules/aws-velero"
  backup_bucket_name = "my-cluster-velero"
  project            = "sighup-staging"
}

More information on modules inputs can be found in the aws-velero module documentation
Here you can find an example designed to create all necessary cloud resources for Velero on AWS.

Define a kustomization.yaml that includes the downloaded resources.

resources:
  - ./vendor/katalog/dr/velero/velero-aws
  - ./vendor/katalog/dr/velero/velero-node-agent
  - ./vendor/katalog/dr/velero/velero-schedules

To deploy the packages to your cluster, execute:

kustomize build . | kubectl apply -f -

Velero on GCP

Velero on GCP is based on the Velero GCP Plugin.

It requires the secret cloud-credentials in the kube-system namespace containing a service account with appropriate credentials. As an alternative, the module supports workload identity.

Check the required Velero GCP plugin permissions here

To deploy Velero on GCP:

List the packages you want to deploy and their version in a Furyfile.yml

bases:
  - name: dr/velero/velero-gcp
    version: "v2.3.0"
  - name: dr/velero/velero-node-agent
    version: "v2.3.0"
  - name: dr/velero/velero-schedules
    version: "v2.3.0"

modules:
  - name: dr/gcp-velero
    version: "v2.3.0"

See furyctl documentation for additional details about Furyfile.yml format.

Execute furyctl legacy vendor -H to download the packages
