Containerization & Orchestration Glossary

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

Init Container Pattern

Design pattern using specialized containers that run before app containers in a pod, used for setup or dependency management.

Init Containers

Specialized containers that run to completion before other containers in a Kubernetes pod, used for initialization tasks.

Init Containers Resources

Specification of CPU and memory limits for initialization containers in Kubernetes pods, ensuring efficient resource utilization.

Initializers

Deprecated Kubernetes feature for dynamically modifying resource configurations before they become visible to the system.

Inter-Container Communication

Methods and patterns for containers within a pod to exchange data and signals, utilizing shared volumes or localhost networking.

IoT Edge Patterns

Architectural designs for deploying and managing containerized applications on edge devices in Internet of Things scenarios.

Istio

Open-source service mesh providing traffic management, security, and observability for cloud-native applications.

Istio Control Plane Components

Core services of the Istio service mesh responsible for configuring proxies and implementing policies.

Istio Destination Rules

Istio traffic management resource defining policies that apply to traffic intended for a service after routing has occurred.

Istio Gateways

Istio resources managing inbound and outbound traffic for the service mesh, providing fine-grained control over traffic flow.

Istio Mixerless Architecture

Istio design that removes the Mixer component, improving performance and scalability of the service mesh.

Istio Service Entries

Istio resources allowing the addition of entries to the service registry, enabling traffic to external dependencies.

Istio Virtual Services

Istio traffic management resources defining a set of traffic routing rules to apply when a host is addressed.

Istio's Ambient Mesh

Istio feature providing a sidecar-less service mesh implementation, reducing resource overhead and simplifying deployment.

Jaeger

Open-source, end-to-end distributed tracing system for monitoring and troubleshooting microservices-based distributed systems.

Jaeger Operator

Kubernetes operator for automated deployment and management of Jaeger tracing infrastructure in container environments.

Jaeger Tracing

Implementation of distributed tracing using Jaeger to monitor and optimize performance in microservices architectures.

Jenkins X

Cloud-native CI/CD solution for Kubernetes, automating the entire software development lifecycle for containerized applications.

Jib

Tool for building optimized Docker and OCI images for Java applications without the need for a Docker daemon.

Job

Kubernetes resource that creates one or more pods to perform a specific task and ensures they successfully complete, ideal for batch processes.

K3s

Lightweight Kubernetes distribution designed for edge, IoT, and resource-constrained environments, simplifying cluster deployment.

K9s CLI

Terminal-based UI for managing and monitoring Kubernetes clusters, providing an intuitive interface for cluster operations.

KEDA (Kubernetes Event-driven Autoscaling)

Kubernetes-based Event Driven Autoscaling, enabling fine-grained autoscaling for event-driven workloads based on event sources.

KUDO (Kubernetes Universal Declarative Operator)

Kubernetes Universal Declarative Operator, a toolkit for writing operators using a declarative spec, simplifying complex application management.

Kaniko

Tool for building container images from a Dockerfile inside a container or Kubernetes cluster, without requiring a Docker daemon.
