kubernetes-client/java

Features

• Kubernetes API Providers - Provides a set of typed models and methods for sending REST and WebSocket requests to the Kubernetes API.
• Kubernetes Cluster Management - Provides a comprehensive Java library for programmatically managing and operating Kubernetes clusters.
• OpenAPI Model Generators - Generates strongly-typed Java classes from the server API specification to ensure type safety.
• Control Loops - Provides a framework for implementing reconciliation loops that align actual resource state with a desired target state.
• Model Generators - Provides mechanisms to generate strongly-typed Java classes from custom resource definitions.
• Resource Lifecycle Automation - Implements automated creation, deletion, and patching of cluster objects using strongly typed Java models.
• Kubernetes API Clients - Provides a Java-based client library for interacting with the Kubernetes control plane.
• Kubernetes Controllers - Provides frameworks for implementing automated control loops and declarative reconciliation for Kubernetes operators.
• State Reconciliation Orchestrators - Enables the implementation of control loops that reconcile the desired state of Kubernetes objects programmatically.
• Remote Cluster Access - Provides programmatic access to control and operate remote cluster environments via a centralized API.
• Cluster Object Watches - Maintains persistent connections to receive real-time notifications about resource changes via API watches.
• Informer Caches - Synchronizes a local memory cache with the server by combining initial list requests with continuous event updates.
• YAML and Protobuf Serialization - Translates resource objects between Java representations and standard YAML or Protobuf wire formats.
• Container Command Executors - Enables the execution of arbitrary commands and interactive shells inside running containers.
• Client Connection Configurations - Enables establishing secure cluster connections using service accounts or external configuration files.
• Resource Listing and Filtering - Provides capabilities for querying and retrieving lists of resource objects across namespaces.
• Cluster Resource Deletions - Provides the capability to remove various objects from a cluster using high-level API calls.
• Distributed Leader Election - Includes coordination mechanisms to ensure only one instance performs specific control operations.
• Container Interaction - Enables executing commands, transferring files, and forwarding ports to interact with containers within a cluster.
• Local Resource Caches - Maintains in-memory mirrors of server-side resources by combining initial listings with continuous watch events.
• Resource Patches - Allows updating specific fields of a resource using partial patch formats without replacing the entire object.
• Kubernetes Pod Port Forwarding - Maps local TCP ports to pod containers by establishing a tunnel through the Kubernetes API server proxy.
• Resource Serialization Systems - Provides a system for loading or dumping resource definitions using YAML or Protobuf protocols.
• Container File Transfers - Provides utilities for copying files and directories between a local filesystem and a running container.
• Container Log Retrieval - Allows fetching stdout and stderr output streams from running containers for debugging and monitoring.
• Real-Time Event Watchers - Implements mechanisms for subscribing to real-time resource change events to maintain synchronized local caches.
• Resource Change Monitors - Supports watching resource event streams to trigger automated operations based on cluster changes.
