Functions

func BuiltInCustomFunctions

func BuiltInCustomFunctions(c *configTemplateBuilder, component *component.SynthesizedComponent, localObjs []client.Object) *gotemplate.BuiltInObjectsFunc

BuiltInCustomFunctions builds a map of customized functions for KubeBlocks

func CheckTLSSecretRef

func CheckTLSSecretRef(ctx context.Context, cli client2.ReadonlyClient, namespace string,
	secretRef *dbaasv1alpha1.TLSSecretRef) error

func ComposeTLSSecret

func ComposeTLSSecret(namespace, clusterName, componentName string) (*v1.Secret, error)

ComposeTLSSecret composes a TSL secret object. REVIEW/TODO:

1. missing public function doc
2. should avoid using Go template to call a function, this is too hacky & costly, should just call underlying registered Go template function.

func DoPITR

func DoPITR(ctx context.Context, cli client.Client, cluster *appsv1alpha1.Cluster,
	component *component.SynthesizedComponent, schema *k8sruntime.Scheme) error

DoPITR prepares PITR jobs

func DoRestore

func DoRestore(ctx context.Context, cli client.Client, cluster *appsv1alpha1.Cluster,
	component *component.SynthesizedComponent, schema *k8sruntime.Scheme) error

DoRestore prepares restore jobs

func GenerateTLSSecretName

func GenerateTLSSecretName(clusterName, componentName string) string

func GetTLSKeyWord

func GetTLSKeyWord(cType string) string

func RenderConfigNScriptFiles

func RenderConfigNScriptFiles(clusterVersion *appsv1alpha1.ClusterVersion,
	cluster *appsv1alpha1.Cluster,
	component *component.SynthesizedComponent,
	obj client.Object,
	podSpec *corev1.PodSpec,
	localObjs []client.Object,
	ctx context.Context,
	cli client.Client) ([]client.Object, error)

RenderConfigNScriptFiles generates volumes for PodTemplate, volumeMount for container, rendered configTemplate and scriptTemplate, and generates configManager sidecar for the reconfigure operation. TODO rename this function, this function name is not very reasonable, but there is no suitable name.

Types

type ResourceDefinition

type ResourceDefinition struct {
	MemorySize int64 `json:"memorySize,omitempty"`
	CoreNum    int64 `json:"coreNum,omitempty"`
}

type RestoreManager

type RestoreManager struct {
	client.Client
	Ctx     context.Context
	Cluster *appsv1alpha1.Cluster
	Scheme  *k8sruntime.Scheme
	// contains filtered or unexported fields
}

RestoreManager restores manager functions 1. support datafile/snapshot restore 2. support point in time recovery (PITR)

type TemplateMerger

type TemplateMerger interface {

	// Merge merges the baseData with the data from the template.
	Merge(baseData map[string]string, updatedData map[string]string) (map[string]string, error)
	// contains filtered or unexported methods
}

func NewTemplateMerger

func NewTemplateMerger(template appsv1alpha1.LazyRenderedTemplateSpec, ctx context.Context, cli client.Client, builder *configTemplateBuilder, configSpec appsv1alpha1.ComponentConfigSpec, ccSpec *appsv1alpha1.ConfigConstraintSpec) (TemplateMerger, error)
