Features

• Container Runtime Debuggings - Provides a command-line interface for inspecting, managing, and troubleshooting containers and sandboxes directly on a host machine.
• Container Runtime Interfaces - Provides a diagnostic tool for interacting with and validating container runtimes that implement the Kubernetes Container Runtime Interface.
• Container Lifecycle Orchestrators - Provides a direct interface for managing container lifecycles by translating user inputs into specific runtime API calls.
• Runtime Validation Suites - Verifies that container runtimes strictly adhere to Kubernetes interface specifications and performance requirements.
• Runtime Specification Validators - Verifies that a container runtime correctly implements required interface specifications through automated compliance testing.
• Container Lifecycle Management - Performs core operations including creating, starting, stopping, and inspecting containers and sandboxes.
• Compliance Verifiers - Verifies that container runtimes strictly adhere to defined interface specifications through automated compliance test suites.
• Specification Compliance Testing - Validates container runtime behavior by executing automated test suites against defined interface specifications.
• Performance Benchmarks - Measures container runtime latency and throughput through automated performance benchmarking tools.
• Container Command Executors - Enables running arbitrary commands inside active containers to facilitate real-time debugging and state validation.
• Container Checkpointing - Exports the current state of a running container to a file to facilitate backups and system migrations.
• Container Image Management - Supports pulling, listing, filtering, and removing container images to prepare local environments.
• Container Runtime Managers - Manages connections to container runtimes to perform lifecycle operations like starting, stopping, and removing containers.
• Container Runtime Debugging - Inspects and interacts with container runtimes directly on a host machine to troubleshoot pods and images.
• Runtime Connectivity - Ensures reliable communication with runtime endpoints using configurable retry logic and exponential backoff policies.
• gRPC Stream Testing - Validates the stability of interactive streaming connections like exec, attach, and port-forwarding over websocket protocols.
• Stream Multiplexers - Handles interactive container sessions by multiplexing data streams over websocket connections for real-time command execution.
• Resource Integration Plugins - Verifies system compatibility by simulating external resource management plugins and measuring runtime responses to lifecycle hooks.
• Metric and Performance Monitors - Measures and reports latency and resource consumption metrics for CPU, memory, disk, and network usage.
• Container - Measures the latency and throughput of container operations to assess system efficiency.
• System Usage Monitoring - Retrieves structured metrics and resource statistics for pods and containers to assess system health.
• Runtime State Inspection - Queries runtime state to retrieve detailed diagnostic information about pods, containers, and images.
• Performance Benchmarking Tools - Provides utilities for measuring latency, throughput, and resource consumption metrics of container runtimes.
• Cloud Native Security - Tools for interacting with container runtimes.
• Diagnostics and Troubleshooting - Validates and debugs container runtime interfaces.
• Cloud Security - CLI tools for interacting with container runtimes.
