Default: {}

spec.deployment: ObjectPermalink

ArangoDeployment specification.

Field is immutable.

Required: true

Default: {}

spec.deployment.name: StringPermalink

Name of the ArangoDeployment Custom Resource within same namespace as ArangoBackup Custom Resource.

Field is immutable.

Required: true

Default: “”

spec.policyName: StringPermalink

Name of the ArangoBackupPolicy which created this Custom Resource

Field is immutable.

Required: false

Default: “”

spec.options: ObjectPermalink

Field is immutable.

Required: false

Default: false

spec.download: ObjectPermalink

Backup download settings.

Field is immutable.

Required: false

Default: {}

spec.download.repositoryURL: stringPermalink

Field is immutable. Protocol needs to be defined in spec.download.credentialsSecretName if protocol is other than local.

Mode protocols can be found at rclone.org.

Format: <protocol>:/<path>

Examples:

• s3://my-bucket/test
• azure://test

Required: true

Default: “”

spec.download.credentialsSecretName: stringPermalink

Field is immutable. Name of the secret used while accessing repository

Secret structure:

apiVersion: v1
data:
  token: <json token>
kind: Secret
metadata:
  name: <name>
type: Opaque

JSON Token options are described on the rclone page. We can define more than one protocols at same time in one secret.

This field is defined in json format:

{
  "<protocol>": {
    "type":"<type>",
    ...parameters
    }
}

AWS S3 example - based on rclone S3 documentation and interactive process:

{
  "S3": {
    "type": "s3", # Choose s3 type
    "provider": "AWS", # Choose one of the providers
    "env_auth": "false", # Define credentials in next step instead of using ENV
    "access_key_id": "xxx",
    "secret_access_key": "xxx",
    "region": "eu-west-2", # Choose region
    "acl": "private", # Set permissions on newly created remote object
  }
}

and you can from now use S3://bucket/path.
