Backup API type is used as a request for the Ark Server to perform a backup. Once created, the
Ark Server immediately starts the backup process.
Backup belongs to the API group version
Here is a sample
Backup object with each of the fields documented:
# Standard Kubernetes API Version declaration. Required. apiVersion: ark.heptio.com/v1 # Standard Kubernetes Kind declaration. Required. kind: Backup # Standard Kubernetes metadata. Required. metadata: # Backup name. May be any valid Kubernetes object name. Required. name: a # Backup namespace. Required. In version 0.7.0 and later, can be any string. Must be the namespace of the Ark server. namespace: heptio-ark # Parameters about the backup. Required. spec: # Array of namespaces to include in the backup. If unspecified, all namespaces are included. # Optional. includedNamespaces: - '*' # Array of namespaces to exclude from the backup. Optional. excludedNamespaces: - some-namespace # Array of resources to include in the backup. Resources may be shortcuts (e.g. 'po' for 'pods') # or fully-qualified. If unspecified, all resources are included. Optional. includedResources: - '*' # Array of resources to exclude from the backup. Resources may be shortcuts (e.g. 'po' for 'pods') # or fully-qualified. Optional. excludedResources: - storageclasses.storage.k8s.io # Whether or not to include cluster-scoped resources. Valid values are true, false, and # null/unset. If true, all cluster-scoped resources are included (subject to included/excluded # resources and the label selector). If false, no cluster-scoped resources are included. If unset, # all cluster-scoped resources are included if and only if all namespaces are included and there are # no excluded namespaces. Otherwise, if there is at least one namespace specified in either # includedNamespaces or excludedNamespaces, then the only cluster-scoped resources that are backed # up are those associated with namespace-scoped resources included in the backup. For example, if a # PersistentVolumeClaim is included in the backup, its associated PersistentVolume (which is # cluster-scoped) would also be backed up. includeClusterResources: null # Individual objects must match this label selector to be included in the backup. Optional. labelSelector: matchLabels: app: ark component: server # Whether or not to snapshot volumes. This only applies to PersistentVolumes for Azure, GCE, and # AWS. Valid values are true, false, and null/unset. If unset, Ark performs snapshots as long as # a persistent volume provider is configured for Ark. snapshotVolumes: null # The amount of time before this backup is eligible for garbage collection. ttl: 24h0m0s # Actions to perform at different times during a backup. The only hook currently supported is # executing a command in a container in a pod using the pod exec API. Optional. hooks: # Array of hooks that are applicable to specific resources. Optional. resources: - # Name of the hook. Will be displayed in backup log. name: my-hook # Array of namespaces to which this hook applies. If unspecified, the hook applies to all # namespaces. Optional. includedNamespaces: - '*' # Array of namespaces to which this hook does not apply. Optional. excludedNamespaces: - some-namespace # Array of resources to which this hook applies. The only resource supported at this time is # pods. includedResources: - pods # Array of resources to which this hook does not apply. Optional. excludedResources:  # This hook only applies to objects matching this label selector. Optional. labelSelector: matchLabels: app: ark component: server # An array of hooks to run before executing custom actions. Currently only "exec" hooks are supported. # DEPRECATED. Use pre instead. hooks: # Same content as pre below. # An array of hooks to run before executing custom actions. Currently only "exec" hooks are supported. pre: - # The type of hook. This must be "exec". exec: # The name of the container where the command will be executed. If unspecified, the # first container in the pod will be used. Optional. container: my-container # The command to execute, specified as an array. Required. command: - /bin/uname - -a # How to handle an error executing the command. Valid values are Fail and Continue. # Defaults to Fail. Optional. onError: Fail # How long to wait for the command to finish executing. Defaults to 30 seconds. Optional. timeout: 10s # An array of hooks to run after all custom actions and additional items have been # processed. Currently only "exec" hooks are supported. post: # Same content as pre above. # Status about the Backup. Users should not set any data here. status: # The date and time when the Backup is eligible for garbage collection. expiration: null # The current phase. Valid values are New, FailedValidation, InProgress, Completed, Failed. phase: "" # An array of any validation errors encountered. validationErrors: null # The version of this Backup. The only version currently supported is 1. version: 1 # Information about PersistentVolumes needed during restores. volumeBackups: # Each key is the name of a PersistentVolume. some-pv-name: # The ID used by the cloud provider for the snapshot created for this Backup. snapshotID: snap-1234 # The type of the volume in the cloud provider API. type: io1 # The availability zone where the volume resides in the cloud provider. availabilityZone: my-zone # The amount of provisioned IOPS for the volume. Optional. iops: 10000
