  • Kubernetes Ingress

    A Kubernetes resource that tells the cluster how to route incoming web traffic from outside to the right internal Service using rules like hostnames and paths.

    Networking

  • Kubernetes Operators

    Kubernetes-native controllers that run an app for you by automating deploys, configuration, and ongoing operations using custom resources.

    Container Orchestration

  • Karpenter

    Automates node scaling in Kubernetes clusters.

    Infrastructure Management

  • KRO

    KRO orchestrates related Kubernetes resources as one unit using templates and rules to standardize platform deployments.

    Container Orchestration

  • Kubernetes

    Open source container orchestration platform that deploys, scales, and manages containerized applications across clusters.

    Container Orchestration

  • Kubernetes Network Policy

    Rules that say which pods in a Kubernetes cluster are allowed to talk to which other pods or services over the network.

    Networking

  • Kubernetes Admission Controller

    Kubernetes Admission Controller checks API calls to allow, change, or deny cluster changes before saving them.

    Container Orchestration

  • Kubernetes Service

    A Kubernetes Service is a stable network endpoint that exposes pods and routes traffic within or outside a cluster.

    Container Orchestration

  • Kubernetes NetworkPolicy

    Kubernetes NetworkPolicy sets rules for pod traffic in a cluster, controlling which pods can connect to other pods.

    Container Orchestration

  • Kubernetes RBAC

    Kubernetes RBAC controls which users, groups, or service accounts can perform actions on cluster resources to limit access.

    Authentication and Authorization

  • Kubernetes StatefulSet

    Kubernetes StatefulSet is a workload API object for stateful pods, giving each pod stable identity and storage.

    Container Orchestration

  • Kubernetes Operator

    A Kubernetes Operator is a controller that automates app lifecycle management in a cluster using custom resources.

    Container Orchestration

  • Kubernetes DaemonSet

    Kubernetes DaemonSet is a workload API object that runs one pod on each selected node for cluster-wide node agents.

    Container Orchestration

  • Kubernetes Deployment

    A Kubernetes Deployment is a workload API object that manages replicated pods and rolling updates in a cluster.

    Container Orchestration

  • Kubernetes ConfigMap

    A Kubernetes ConfigMap is an API object storing non-sensitive configuration for pods, separate from container images.

    Container Orchestration

  • Kubernetes Secret

    A Kubernetes Secret is an API object for sensitive data, such as tokens or passwords, used by pods.

    Secrets Management

  • Kubernetes PersistentVolume (PV)

    A Kubernetes PV is a cluster storage resource that lets pods keep data beyond restarts through bound claims.

    Container Orchestration

  • Kubernetes Pod

    A Kubernetes Pod is the smallest deployable cluster unit, running one or more containers that share a network.

    Container Orchestration

  • Kubernetes CronJob

    A Kubernetes CronJob creates Jobs on a schedule to automate recurring tasks inside a cluster, like backups or cleanup.

    Container Orchestration

  • Kubernetes Job

    A Kubernetes Job runs one or more pods to completion for finite tasks, such as batch processing inside a cluster.

    Container Orchestration

  • Kubernetes ServiceAccount

    A Kubernetes ServiceAccount is an identity for pods to authenticate to the API server and access cluster resources.

    Authentication and Authorization

  • Kubernetes Liveness Probe

    A Kubernetes liveness probe checks whether a container is alive and restarts it when the app stops responding.

    Container Orchestration

  • Kubernetes Readiness Probe

    A Kubernetes readiness probe checks whether a pod is ready for traffic before adding it to Service endpoints.

    Container Orchestration

  • Kubernetes Init Container

    A Kubernetes init container runs before app containers in a pod to prepare dependencies, config, or setup tasks.

    Container Orchestration

  • Kubernetes Node

    A Kubernetes Node is a worker machine in a cluster that runs pods and provides CPU, memory, and networking for workloads.

    Container Orchestration

  • Kubernetes Namespace

    A Kubernetes Namespace is a logical partition in a cluster used to group resources and scope access, policies, or quotas.

    Container Orchestration

  • Kubernetes ReplicaSet

    A Kubernetes ReplicaSet keeps a set number of matching pods running in a cluster, replacing failed ones as needed.

    Container Orchestration

  • Kubernetes Taints and Tolerations

    Kubernetes taints and tolerations control scheduling by marking nodes and allowing only matching pods to run there.

    Container Orchestration

  • Kubernetes StorageClass

    Kubernetes StorageClass defines volume provisioning settings for PVCs, letting teams request storage by class.

    Container Orchestration

  • Kubernetes EndpointSlice

    Kubernetes EndpointSlice groups Service endpoints into slices so controllers and proxies can route traffic to pods.

    Container Orchestration

  • Kubernetes Volume

    Kubernetes Volume is a storage resource attached to a pod, used to persist or share data across containers.

    Container Orchestration

  • Kubernetes Gateway API

    Kubernetes Gateway API defines Kubernetes resources for managing service traffic routing into clusters with gateway, route, and policy objects.

    Networking

  • Kubernetes ResourceQuota

    Kubernetes ResourceQuota is a namespace limit for CPU, memory, storage, and objects that controls cluster use.

    Container Orchestration

  • Kubernetes ClusterRole

    Kubernetes ClusterRole is a cluster-wide RBAC role that defines access to namespace and cluster resources.

    Authentication and Authorization

  • Kubernetes RoleBinding

    Kubernetes RoleBinding assigns a Role’s namespace permissions to users, groups, or service accounts for RBAC control.

    Authentication and Authorization

  • Kubernetes ClusterRoleBinding

    Kubernetes ClusterRoleBinding maps a ClusterRole to users, groups, or service accounts for cluster-wide RBAC access.

    Authentication and Authorization

  • Kubernetes PriorityClass

    Kubernetes PriorityClass sets pod priority, allowing critical workloads to preempt lower-priority pods when cluster resources are scarce.

    Container Orchestration

  • Kubernetes SecurityContext

    Kubernetes SecurityContext defines Pod or container security settings, controlling runtime privileges, user IDs, and Linux capabilities.

    Security

  • Kubernetes Role

    Kubernetes Role is a namespaced RBAC object that defines allowed actions on resources, applied through RoleBindings.

    Authentication and Authorization

  • Kubernetes Labels and Selectors

    Kubernetes labels are key-value tags on objects, and selectors match them to group Pods for services or controllers.

    Container Orchestration

  • Kubernetes VolumeSnapshot

    A Kubernetes VolumeSnapshot captures a point-in-time PVC copy for backup, restore, or storage cloning workflows.

    Container Orchestration

  • Kubernetes IngressClass

    Kubernetes IngressClass links an Ingress to the controller that routes outside traffic for cluster services.
