Types

type JobTemplateSpec 

type JobTemplateSpec struct {
	// Specifies the duration in seconds relative to the startTime that the job
	// may be continuously active before the system tries to terminate it; value
	// must be positive integer.
	// Do not set too short or you will run into PVC/VolumeSnapshot provisioning rate limits.
	// Defaults to 24 hours.
	// +kubebuilder:validation:Minimum:=1
	// +optional
	ActiveDeadlineSeconds *int64 `json:"activeDeadlineSeconds"`

	// Specifies the number of retries before marking this job failed.
	// Defaults to 5.
	// +kubebuilder:validation:Minimum:=0

	BackoffLimit *int32 `json:"backoffLimit"`

	// Limits the lifetime of a Job that has finished
	// execution (either Complete or Failed). If this field is set,
	// ttlSecondsAfterFinished after the Job finishes, it is eligible to be
	// automatically deleted. When the Job is being deleted, its lifecycle
	// guarantees (e.g. finalizers) will be honored. If this field is set to zero,
	// the Job becomes eligible to be deleted immediately after it finishes.

	// +optional
	Suspend bool `json:"suspend"`
}

ScheduledVolumeSnapshotSpec defines the desired state of ScheduledVolumeSnapshot Creates recurring VolumeSnapshots of a PVC managed by a CosmosFullNode. A VolumeSnapshot is a CRD (installed in GKE by default). See: https://kubernetes.io/docs/concepts/storage/volume-snapshots/ This enables recurring, consistent backups. To prevent data corruption, a pod is temporarily deleted while the snapshot takes place which could take several minutes. Therefore, if you create a ScheduledVolumeSnapshot, you must use replica count >= 2 to prevent downtime. If <= 1 pod in a ready state, the controller will not temporarily delete the pod. The controller makes every effort to prevent downtime. Only 1 VolumeSnapshot is created at a time, so at most only 1 pod is temporarily deleted. Multiple, parallel VolumeSnapshots are not supported.
