• How Velero works

Storage

Data from velero is stored in object storage and configuration is based upon the provider.

Istio Configuration

Istio is disabled in the velero chart by default and can be enabled by setting the following values in the bigbang chart:

istio:
  enabled: true

These values get passed into the velero chart here.

High Availability

Velero does not have configurations for high availability.

Single Sign on (SSO)

None. This service doesn't have a web interface.

Licensing

Apache 2.0 License

Dependencies

Velero requires an object storage service available with the bucket details pre-configured. This can be block storage from block storage from AWS, Azure or other providers. minio and miniooperator can be enabled to provide this storage local to the cluster under the addon packages.
