TK8 addon - Velero (minio)

What are TK8 addons?

• TK8 add-ons provide freedom of choice for the user to deploy tools and applications without being tied to any customized formats of deployment.
• Simplified deployment process via CLI (will also be available via TK8 web in future).
• With the TK8 add-ons platform, you can also build your own add-ons.

What is Velero?

Velero (formerly Heptio Ark) gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. Velero lets you:

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

Get started

You need

• A kubernetes cluster.
• A default storage class defined. Velero doesn't support hostPath volumes for backup and restore
• TK8 binary

Deploy velero-minio on the Kubernetes Cluster

Run tk8 addon install velero-minio

$ tk8 addon install velero-minio
Install velero-minio velero-minio
execute main.sh
apply main.yml

velero-minio installation complete

This command will clone the kubernauts' velero-minio repository (https://github.com/kubernauts/tk8-addon-velero-minio) locally and install the necessary components.

This command creates:

• Velero namespace
• Secrets , ServiceAccount and Roles and RoleBindings for velero
• Custom Resource Definitions for Velero
• Velero and Restic Deployment for Taking backup and restore
• Minio Object store deployment for storing backups

If all goes, you should see all resources in Running state:

Uninstalling Velero minio

For removing velero-minio from your cluster, we can use TK8 addon's destroy functionality. Run tk8 addon destroy velero-minio

$ tk8 addon destroy velero-minio
