Types

type Action 

type Action struct {
	// Defines the command to run.
	//
	// This field cannot be updated.
	//
	// +optional
	Exec *ExecAction `json:"exec,omitempty"`

	// Specifies the maximum duration in seconds that the Action is allowed to run.
	//
	// If the Action does not complete within this time frame, it will be terminated.
	//
	// This field cannot be updated.
	//
	// +kubebuilder:default=0
	// +optional
	TimeoutSeconds int32 `json:"timeoutSeconds,omitempty"`

	// Defines the strategy to be taken when retrying the Action after a failure.
	//
	// It specifies the conditions under which the Action should be retried and the limits to apply,
	// such as the maximum number of retries and backoff strategy.
	//
	// This field cannot be updated.
	//
	// +optional
	RetryPolicy *RetryPolicy `json:"retryPolicy,omitempty"`

	// Specifies the state that the cluster must reach before the Action is executed.
	// Currently, this is only applicable to the `postProvision` action.
	//
	// The conditions are as follows:
	//
	// - `Immediately`: Executed right after the Component object is created.
	//   The readiness of the Component and its resources is not guaranteed at this stage.
	// - `RuntimeReady`: The Action is triggered after the Component object has been created and all associated
	//   runtime resources (e.g. Pods) are in a ready state.
	// - `ComponentReady`: The Action is triggered after the Component itself is in a ready state.
	//   This process does not affect the readiness state of the Component or the Cluster.
	// - `ClusterReady`: The Action is executed after the Cluster is in a ready state.
	//   This execution does not alter the Component or the Cluster's state of readiness.
	//
	// This field cannot be updated.
	//
	// +optional
	PreCondition *PreConditionType `json:"preCondition,omitempty"`
}

Action defines a customizable hook or procedure tailored for different database engines, designed to be invoked at predetermined points within the lifecycle of a Component instance. It provides a modular and extensible way to customize a Component's behavior through the execution of defined actions.

Available Action triggers include:

  • `postProvision`: Defines the hook to be executed after the creation of a Component, with `preCondition` specifying when the action should be fired relative to the Component's lifecycle stages: `Immediately`, `RuntimeReady`, `ComponentReady`, and `ClusterReady`.
  • `preTerminate`: Defines the hook to be executed before terminating a Component.
  • `roleProbe`: Defines the procedure which is invoked regularly to assess the role of replicas.
  • `switchover`: Defines the procedure for a controlled transition of leadership from the current leader to a new replica. This approach aims to minimize downtime and maintain availability in systems with a leader-follower topology, such as during planned maintenance or upgrades on the current leader node.
  • `memberJoin`: Defines the procedure to add a new replica to the replication group.
  • `memberLeave`: Defines the method to remove a replica from the replication group.
  • `readOnly`: Defines the procedure to switch a replica into the read-only state.
  • `readWrite`: Defines the procedure to transition a replica from the read-only state back to the read-write state.
  • `dataDump`: Defines the procedure to export the data from a replica.
  • `dataLoad`: Defines the procedure to import data into a replica.
  • `reconfigure`: Defines the procedure that update a replica with new configuration.
  • `accountProvision`: Defines the procedure to generate a new database account.

Actions can be executed in different ways:

  • ExecAction: Executes a command inside a container. A set of predefined environment variables are available and can be leveraged within the `exec.command` to access context information such as details about pods, components, the overall cluster state, or database connection credentials. These variables provide a dynamic and context-aware mechanism for script execution.
  • HTTPAction: Performs an HTTP request. HTTPAction is to be implemented in future version.
  • GRPCAction: In future version, Actions will support initiating gRPC calls. This allows developers to implement Actions using plugins written in programming language like Go, providing greater flexibility and extensibility.

An action is considered successful on returning 0, or HTTP 200 for status HTTP(s) Actions. Any other return value or HTTP status codes indicate failure, and the action may be retried based on the configured retry policy.

  • If an action exceeds the specified timeout duration, it will be terminated, and the action is considered failed.
  • If an action produces any data as output, it should be written to stdout, or included in the HTTP response payload for HTTP(s) actions.
  • If an action encounters any errors, error messages should be written to stderr, or detailed in the HTTP response with the appropriate non-200 status code.

type Cluster 

type Cluster struct {
	metav1.TypeMeta   `json:",inline"`

	Spec   ClusterSpec   `json:"spec,omitempty"`
	Status ClusterStatus `json:"status,omitempty"`
}

Cluster offers a unified management interface for a wide variety of database and storage systems:

- Relational databases: MySQL, PostgreSQL, MariaDB - NoSQL databases: Redis, MongoDB - KV stores: ZooKeeper, etcd - Analytics systems: ElasticSearch, OpenSearch, ClickHouse, Doris, StarRocks, Solr - Message queues: Kafka, Pulsar - Distributed SQL: TiDB, OceanBase - Vector databases: Qdrant, Milvus, Weaviate - Object storage: Minio

KubeBlocks utilizes an abstraction layer to encapsulate the characteristics of these diverse systems. A Cluster is composed of multiple Components, each defined by vendors or KubeBlocks Addon developers via ComponentDefinition, arranged in Directed Acyclic Graph (DAG) topologies. The topologies, defined in a ClusterDefinition, coordinate reconciliation across Cluster's lifecycle phases: Creating, Running, Updating, Stopping, Stopped, Deleting. Lifecycle management ensures that each Component operates in harmony, executing appropriate actions at each lifecycle stage.

For sharded-nothing architecture, the Cluster supports managing multiple shards, each shard managed by a separate Component, supporting dynamic resharding.

The Cluster object is aimed to maintain the overall integrity and availability of a database cluster, serves as the central control point, abstracting the complexity of multiple-component management, and providing a unified interface for cluster-wide operations.

	// Allows for the customization of configuration values for each instance within a Component.
	// An instance represent a single replica (Pod and associated K8s resources like PVCs, Services, and ConfigMaps).
	// While instances typically share a common configuration as defined in the ClusterComponentSpec,
	// they can require unique settings in various scenarios:
	//
	// For example:
	// - A database Component might require different resource allocations for primary and secondary instances,
	//   with primaries needing more resources.
	// - During a rolling upgrade, a Component may first update the image for one or a few instances,
	//   and then update the remaining instances after verifying that the updated instances are functioning correctly.
	//
	// InstanceTemplate allows for specifying these unique configurations per instance.
	// Each instance's name is constructed using the pattern: $(component.name)-$(template.name)-$(ordinal),
	// starting with an ordinal of 0.
	// It is crucial to maintain unique names for each InstanceTemplate to avoid conflicts.
	//
	// The sum of replicas across all InstanceTemplates should not exceed the total number of replicas specified for the Component.
	// Any remaining replicas will be generated using the default template and will follow the default naming rules.

	Instances []InstanceTemplate `json:"instances,omitempty" patchStrategy:"merge,retainKeys" patchMergeKey:"name"`

	// Specifies the names of instances to be transitioned to offline status.
	//
	// Marking an instance as offline results in the following:
	//
	// 1. The associated Pod is stopped, and its PersistentVolumeClaim (PVC) is retained for potential
	//    future reuse or data recovery, but it is no longer actively used.
	// 2. The ordinal number assigned to this instance is preserved, ensuring it remains unique
	//    and avoiding conflicts with new instances.
	//
	// Setting instances to offline allows for a controlled scale-in process, preserving their data and maintaining
	// ordinal consistency within the Cluster.
	// Note that offline instances and their associated resources, such as PVCs, are not automatically deleted.
	// The administrator must manually manage the cleanup and removal of these resources when they are no longer needed.
	//
	// +optional
	OfflineInstances []string `json:"offlineInstances,omitempty"`

	// Determines whether metrics exporter information is annotated on the Component's headless Service.
	//

	//
	// - "monitor.kubeblocks.io/path"
	// - "monitor.kubeblocks.io/port"
	// - "monitor.kubeblocks.io/scheme"
	//
	// These annotations allow the Prometheus installed by KubeBlocks to discover and scrape metrics from the exporter.

}

ComponentDefinition serves as a reusable blueprint for creating Components, encapsulating essential static settings such as Component description, Pod templates, configuration file templates, scripts, parameter lists, injected environment variables and their sources, and event handlers. ComponentDefinition works in conjunction with dynamic settings from the ClusterComponentSpec, to instantiate Components during Cluster creation.

Key aspects that can be defined in a ComponentDefinition include:

- PodSpec template: Specifies the PodSpec template used by the Component. - Configuration templates: Specify the configuration file templates required by the Component. - Scripts: Provide the necessary scripts for Component management and operations. - Storage volumes: Specify the storage volumes and their configurations for the Component. - Pod roles: Outlines various roles of Pods within the Component along with their capabilities. - Exposed Kubernetes Services: Specify the Services that need to be exposed by the Component. - System accounts: Define the system accounts required for the Component. - Monitoring and logging: Configure the exporter and logging settings for the Component.

ComponentDefinitions also enable defining reactive behaviors of the Component in response to events, such as member join/leave, Component addition/deletion, role changes, switch over, and more. This allows for automatic event handling, thus encapsulating complex behaviors within the Component.

Referencing a ComponentDefinition when creating individual Components ensures inheritance of predefined configurations, promoting reusability and consistency across different deployments and cluster topologies.

ServiceRefDeclaration represents a reference to a service that can be either provided by a KubeBlocks Cluster or an external service. It acts as a placeholder for the actual service reference, which is determined later when a Cluster is created.

The purpose of ServiceRefDeclaration is to declare a service dependency without specifying the concrete details of the service. It allows for flexibility and abstraction in defining service references within a Component. By using ServiceRefDeclaration, you can define service dependencies in a declarative manner, enabling loose coupling and easier management of service references across different components and clusters.

Upon Cluster creation, the ServiceRefDeclaration is bound to an actual service through the ServiceRef field, effectively resolving and connecting to the specified service.

type UpdateStrategy 

type UpdateStrategy string

UpdateStrategy defines the update strategy for cluster components. This strategy determines how updates are applied across the cluster. The available strategies are `Serial`, `BestEffortParallel`, and `Parallel`.

+enum +kubebuilder:validation:Enum={Serial,BestEffortParallel,Parallel} 

const (
	// SerialStrategy indicates that updates are applied one at a time in a sequential manner.
	// The operator waits for each replica to be updated and ready before proceeding to the next one.
	// This ensures that only one replica is unavailable at a time during the update process.
	SerialStrategy UpdateStrategy = "Serial"

	// ParallelStrategy indicates that updates are applied simultaneously to all Pods of a Component.
	// The replicas are updated in parallel, with the operator updating all replicas concurrently.
	// This strategy provides the fastest update time but may lead to a period of reduced availability or
	// capacity during the update process.
	ParallelStrategy UpdateStrategy = "Parallel"

	// BestEffortParallelStrategy indicates that the replicas are updated in parallel, with the operator making
	// a best-effort attempt to update as many replicas as possible concurrently
	// while maintaining the component's availability.
	// Unlike the `Parallel` strategy, the `BestEffortParallel` strategy aims to ensure that a minimum number
	// of replicas remain available during the update process to maintain the component's quorum and functionality.
	//
	// For example, consider a component with 5 replicas. To maintain the component's availability and quorum,
	// the operator may allow a maximum of 2 replicas to be simultaneously updated. This ensures that at least
	// 3 replicas (a quorum) remain available and functional during the update process.
	//
	// The `BestEffortParallel` strategy strikes a balance between update speed and component availability.
