Ingress 控制器
A Kubernetes resource that manages external access to services in a cluster, typically via HTTP/HTTPS routing and load balancing.
View termIngress控制器
A specialized load balancer that manages external access to services in a containerized cluster, routing HTTP(S) and other traffic based on policies.
View termPod 中断
Pod Disruption refers to the interruption or forced removal of pods from a node, whether planned or unplanned, impacting running workloads.
View termPod 安全
Pod Security refers to the policies and controls applied to Kubernetes pods to enforce isolation, least privilege, and protection against security threats.
View termPod 模板
A Pod Template is a Kubernetes object that defines the specification for creating pods, including containers, resources, and labels, used by controllers for replication.
View termPod 调度
The automated process within an orchestrator (e.g., Kubernetes) that assigns pods to suitable nodes based on resource availability and policies.
View termPod 驱逐
Pod Eviction is the process by which Kubernetes forcibly removes a pod from a node, usually due to resource pressure, policy, or node maintenance.
View termPod调度
The automated process by which an orchestration system assigns pods to available nodes, optimizing for workload distribution, resource constraints, and policy compliance.
View term作业执行
Job Execution in Kubernetes refers to running batch or one-off tasks to completion, managed by the Job resource.
View term准入控制器
Admission Controller is a Kubernetes component that intercepts requests to the API server before persistence, enforcing security, policy, or custom logic.
View term副本集
A Replica Set ensures that a specified number of pod replicas are running at all times in a Kubernetes cluster, automatically replacing pods if they fail.
View term存活探针
A Liveness Probe is a health check used by Kubernetes to determine if a container is running. If it fails, the container is restarted automatically.
View term定时作业
A Cron Job is a Kubernetes resource that runs jobs on a scheduled recurring basis, similar to the Unix cron utility.
View term容器运行时
The software component that executes containers, managing lifecycle operations such as image pull, start, stop, and resource isolation per runtime standards.
View term容器运行时
The software component that executes and manages containerized applications on a host, interfacing with the OS kernel and orchestrator.
View term密钥存储
A Secret Store is a secure storage mechanism in Kubernetes or integration platforms for managing sensitive data such as passwords, API keys, and tokens.
View term就绪探针
A Readiness Probe is a Kubernetes mechanism that checks if a container is ready to serve traffic, ensuring only healthy pods receive requests.
View term持久卷
A Persistent Volume is a piece of storage in a Kubernetes cluster provisioned by an administrator or dynamically, independent of the lifecycle of a specific pod.
View term控制器管理器
Controller Manager is a Kubernetes component that runs core controllers, automating tasks such as node management, replication, and endpoint updates.
View term有状态集合
A Stateful Set manages the deployment and scaling of a set of pods, providing each pod with a persistent identity and stable storage.
View term服务发现
Service Discovery is the automatic detection of services and endpoints in a network, allowing applications and systems to find and communicate with each other dynamically.
View term服务网格
An infrastructure layer for managing service-to-service communication, providing observability, security, and control in microservices architectures.
View term服务网格
A dedicated infrastructure layer that manages service-to-service communications, security, observability, and reliability in a microservices architecture.
View term服务账户
A Service Account is an identity assigned to processes running in pods, providing credentials for API access and integration within the cluster.
View term滚动更新
Rolling Update is a deployment strategy in which application instances are gradually replaced with new versions to ensure zero downtime and continuous service availability.
View term端点分片
Endpoint Slice is a Kubernetes API resource that groups network endpoints, providing scalable and efficient service discovery for large clusters.
View term绿色部署
Green Deployment is the new application version deployed in a blue-green deployment strategy, tested and validated before switching production traffic from blue.
View term网络策略
Network Policy defines rules for allowing or denying network traffic to pods or services within a Kubernetes cluster, enhancing security and compliance.
View term自动扩缩容
Auto Scaling automatically adjusts the number of running pods or nodes in response to workload demand, optimizing resource utilization and costs.
View term自定义资源
Custom Resource is a user-defined extension of the Kubernetes API, enabling the management of custom application objects and automation via controllers.
View term节点排空
Node Drain is the process of safely evicting all pods from a Kubernetes node, typically before maintenance or shutdown, to ensure workload continuity.
View term节点选择器
Node Selector is a Kubernetes scheduling mechanism that assigns pods to nodes based on label matching, enabling targeted workload placement.
View term蓝色部署
Blue Deployment is the existing stable version of an application in blue-green deployment strategies, running in production before switching to a new version.
View term负载均衡器
Load Balancer is a network device or software that distributes incoming application traffic across multiple servers or pods to optimize performance and reliability.
View term资源限制
Resource Limit defines the maximum CPU and memory allocation for a container or pod, ensuring stable cluster operation and fair resource usage.
View term运算符模式
Operator Pattern is a design pattern in Kubernetes for automating complex application management using custom controllers and resources.
View term部署回滚
Deployment Rollback is the process of reverting an application deployment to a previous stable version to restore service quickly if an update fails.
View term配置映射
A Config Map stores configuration data as key-value pairs for use by Kubernetes pods and controllers, separating configuration from application code.
View term金丝雀发布
A Canary Release is a deployment technique where a new version is released to a small subset of users or nodes to monitor performance and errors before full rollout.
View term镜像仓库
Image Registry is a centralized repository where container images are stored, managed, and retrieved for deployment in orchestration platforms.
View term集群自动扩缩器
Cluster Autoscaler is a Kubernetes tool that automatically adjusts the number of nodes in a cluster based on pending workloads and resource requirements.
View term集群节点
A physical or virtual machine within a container orchestration cluster, responsible for running containerized workloads and managed as part of a distributed platform.
View term集群节点
