⁠velero-plugin-openstack

An openstack provider for Heptio Velero

[![Build Status][1]][2]

This repository contains example plugins for Velero.

⁠Kinds of Plugins

This repository provides the following kinds of velero plugins:

• Object Store - persists and retrieves backups, backup log files, restore warning/error files, restore logs.
• Block Store - creates snapshots from volumes (during a backup) and volumes from snapshots (during a restore).

⁠Building the plugins

To build the plugins, run

$ make build

To build the image, run

$ make container

This builds an image tagged as cisco-sso/velero-plugin-openstack. If you want to specify a different name, run

$ make container IMAGE=your-repo/your-name:here

⁠Deploying the plugins

To deploy your plugin image to an Velero server:

1. Make sure your image is pushed to a registry that is accessible to your cluster's nodes.
2. Run velero plugin add <image>, e.g. velero plugin add cisco-sso/velero-plugin-openstack

⁠Using the plugins

Note: As of v0.10.0, the Custom Resource Definitions used to define backup and block storage providers have changed. See [the previous docs][3] for using plugins with versions v0.6-v0.9.x.

When the plugin is deployed, it is only made available to use. To make the plugin effective, you must modify your configuration:

Backup storage:

1. Run kubectl edit backupstoragelocation <location-name> -n <velero-namespace> e.g. kubectl edit backupstoragelocation default -n velero OR velero backup-location create <location-name> --provider swift
2. Change the value of spec.provider to openstack to enable an Object Store plugin
3. Save and quit. The plugin will be used for the next backup/restore

Volume snapshot storage:

1. Run kubectl edit volumesnapshotlocation <location-name> -n <velero-namespace> e.g. kubectl edit volumesnapshotlocation default -n velero OR velero snapshot-location create <location-name> --provider cinder An example can be found at examples/06-ark
2. Change the value of spec.provider to enable a Block Store plugin
3. Save and quit. The plugin will be used for the next backup/restore

⁠Examples

To run with the example plugins, do the following:

1. Run velero backup-location create default --provider swift Optional: --config bucket:<your-bucket>,prefix:<your-prefix> to configure a bucket and/or prefix directories.
2. Run velero snapshot-location create example-default --provider cinder
3. Run kubectl edit deployment/velero -n <velero-namespace>
4. Change the value of spec.template.spec.args to look like the following:

      - args:
        - server
        envFrom:
        - secretRef:
            name: cloud-credentials

1. Run kubectl create -f examples/with-pv.yaml to apply a sample nginx application that uses the example block store plugin. Note: This example works best on a virtual machine, as it uses the host's /tmp directory for data storage.
2. Save and quit. The plugins will be used for the next backup/restore
