Performance and resource usage data exposed by container runtimes adhering to the CRI specification.

CRI Runtime Class

Kubernetes feature allowing selection of different runtime configurations for containers, enabling specialized runtimes.

CRI Socket

Unix domain socket used for communication between Kubelet and the CRI-compatible container runtime.

CRI Validation Testing

Process of verifying that a container runtime correctly implements the CRI specification, ensuring compatibility.

CRI-O

Lightweight container runtime specifically designed for Kubernetes, implementing the CRI specification.

CRI-O Internals

Core components and architecture of the CRI-O container runtime, including its interaction with Kubernetes.

CRI-O as Container Runtime

Use of CRI-O, a lightweight container runtime, as the primary runtime in a Kubernetes cluster.

CSI Controller Plugin

Component of CSI responsible for volume provisioning and attachment operations in container orchestration systems.

CSI Drivers

Plugins implementing the Container Storage Interface for various storage systems in Kubernetes.

CSI Ephemeral Volumes

Short-lived volumes in Kubernetes, created and deleted alongside a pod using CSI drivers, for temporary storage.

CSI Migration

Process of transitioning from in-tree volume plugins to CSI drivers in Kubernetes, improving storage extensibility.

CSI Node Plugin

Component of CSI responsible for mounting volumes and making them available to containers.

CSI Topology

Feature allowing storage provisioning based on topology constraints in Kubernetes, optimizing data locality.

Cache-Aside Pattern

Caching strategy where the application checks the cache before retrieving data from the main data store.

Caching Strategies for Containers

Techniques for implementing and managing caches in containerized applications for improved performance.

Calico

Calico eBPF Datapath

High-performance networking mode in Calico using extended Berkeley Packet Filter for packet processing.

Canary Deployments

Technique of releasing new versions to a subset of users or servers to minimize risk and gather feedback.

Capabilities

Fine-grained privileges that can be assigned to containers, enhancing security by limiting root-level access.

Capability Controls

Mechanisms for managing and restricting Linux capabilities assigned to containers for improved security.

Categories

Groupings or classifications of container-related resources or components for easier management and discovery.

Ceph RBD

Ceph's block storage system, often used for persistent volumes in container orchestration platforms.
