containernetworking/cni

Features

• Container Network Interface Specifications - Defines the standard API and plugin model for configuring network interfaces in Linux containers.
• Container Interface Standards - Defines the standard Container Network Interface specification for attaching and detaching network interfaces in containers.
• Container Network Interface Libraries - Ships a Go library for programmatically invoking plugins to set up and tear down container networks.
• Plugin Execution Libraries - Provides a Go library for programmatically invoking plugins and parsing their results.
• CNI Plugins - Ships a Go library and tooling for building plugins that implement the Container Network Interface specification.
• Execution Protocols - Defines a binary protocol and API that orchestrators use to attach, detach, and check container network attachments.
• Container Runtime Integrations - Integrates a standard network interface into container runtimes so orchestrators can manage connectivity in a pluggable way.
• Container Network Attachments - Attaches network interfaces into container network namespaces by executing plugins.
• Container Network - Provides a Go library and specification for building custom container network plugins.
• Container Networking Configurations - Provides a JSON-based configuration schema for declaring network setups and negotiating specification versions.
• Container Networking Tools - Provides a plugin-based mechanism to remove container network interfaces and reclaim associated resources.
• Container Network Detachments - Removes network interfaces and cleans up modifications by running plugins in reverse order.
• Standalone Binary Plugin Executions - Runs network plugins as standalone executables invoked by the container runtime via CLI.
• Sub-Task Delegations - Allows a plugin to invoke separate binaries for specialized tasks like IP address management during network operations.
• CNI Plugin Command-Line Tools - Provides a command-line tool for executing CNI plugins to configure container networking.
• Network Resource Garbage Collections - Automates cleanup of orphaned network resources through a dedicated plugin verb.
• Network Resource Cleanups - Defines a dedicated plugin verb for cleaning up orphaned network resources like IP reservations and firewall rules.
• Orphaned Network Resource Reclamations - Defines a dedicated plugin verb for cleaning up orphaned network resources.
• Attachment Verifications - Ships a standard check operation that plugins implement to verify container network configuration is operational.
• State Verifications - Ships a standard check operation that plugins implement to verify container network configuration is operational.
• Reverse-Order Teardown Protocols - Detaches containers by executing plugins in reverse order of attachment for clean removal.
• Container Network - Supports a wide ecosystem of third-party plugins for overlay networks and policy enforcement.
• Delegated Sub-Plugin Architectures - Allows plugins to delegate specialized tasks like IP address management to separate binaries.
• Container Network Connectivity Verifications - Verifies container network configuration is functioning correctly using the check operation.
• Container Network State Verifications - Ships a standard check operation for plugins to verify network configuration is operational.
• Plugin Readiness Checks - Defines a dedicated plugin verb that runtimes call to check if a plugin can handle new attachment requests.
• Networking & Connectivity - Standard interface for container networking.
