Containerization & Orchestration Glossary

From Docker to Kubernetes to Terraform, your passport to the containerized world of modern deployment.

RoleBindings and ClusterRoleBindings

Kubernetes objects associating Roles and ClusterRoles with users, groups, or service accounts.

Roles and ClusterRoles

Kubernetes RBAC objects defining sets of permissions at namespace or cluster level respectively.

Rollbacks

Process of reverting a deployment to a previous version in case of issues with the current version.

Rolling Updates

Deployment strategy where new versions of an application are gradually rolled out by replacing instances incrementally.

Romana for Layer 3 Networking

Networking solution for Kubernetes providing native Layer 3 networking without overlays for improved performance.

Rook

Open-source cloud-native storage orchestrator for Kubernetes, providing the platform, framework, and support for storage solutions.

Rook Storage Orchestrator

Kubernetes operator for file, block, and object storage systems, automating deployment and management of storage services.

Rootless Containers

Containers running without root privileges, enhancing security by reducing the potential impact of container breakouts.

RunC

Lightweight, portable container runtime adhering to the OCI specification, used as a low-level runtime by container engines.

RunC Internals

Inner workings and components of the RunC container runtime, including its interaction with Linux kernel features.

Runtime Application Self-Protection (RASP)

Security technology that detects and prevents real-time attacks on containerized applications.

Runtime Security

Measures and tools for protecting containerized applications during execution, including threat detection and prevention.

Runtime Threat Detection

Process of identifying and alerting on security threats to running containers and orchestration platforms.

RuntimeService

CRI component responsible for managing the entire lifecycle of a container, including creation, execution, and deletion.

SELinux Policies

Security policies enforcing mandatory access controls on containers and pods in Linux-based systems.

SLO-based Monitoring

Monitoring approach focusing on Service Level Objectives to ensure application performance and reliability.

SMI (Service Mesh Interface)

Standard specification for service meshes on Kubernetes, providing a common interface for various implementations.

SPIFFE/SPIRE for Workload Identity

Standards and implementation for securely identifying and authenticating workloads in dynamic environments.

SR-IOV for Container Networks

Use of Single Root I/O Virtualization to provide high-performance networking for containers.

Saga Pattern

Design pattern for managing data consistency across microservices in distributed transactions.

Saga Pattern for Distributed Transactions

Implementation of the Saga pattern to maintain data consistency in microservices architectures.

Sandbox Runtimes

Container runtimes providing additional isolation between the container and the host system for enhanced security.

Sandboxing

Techniques for isolating running containers from the host system and each other to enhance security.

Scale Subresource

Kubernetes API for directly managing the number of replicas of a workload without modifying the entire object.

Scheduler

Kubernetes component responsible for assigning pods to nodes based on resource requirements, policies, and constraints.
