Principle:Kubeflow Pipelines Deployment Health Verification
Sources: Kubernetes. Domains: Infrastructure, Observability. Last Updated: 2026-02-13.
Overview
A post-deployment verification technique that confirms all service pods have reached Ready state before proceeding with usage.
Description
After applying Kubernetes resources, verification ensures all pods have started, passed health checks, and are in Ready state. This step is essential before attempting to use the services. The label-based selection targets all KFP-related pods. A timeout prevents indefinite waiting.
Usage
Use immediately after deploying KFP resources, before attempting to access the UI or submit pipelines.
Theoretical Basis
Health verification in distributed systems. Pod readiness in Kubernetes indicates the container is passing its readiness probe and accepting traffic.
In a distributed deployment such as Kubeflow Pipelines, multiple interdependent services must all be operational before the system can function correctly. Kubernetes provides a built-in mechanism for this through readiness probes. A pod is marked as Ready only when:
- The container has started successfully
- The readiness probe (HTTP check, TCP check, or exec command) is passing
- The pod is registered with the service endpoint and can accept traffic
Without explicit verification, a user might attempt to access the KFP UI or submit a pipeline before backend services are available, leading to confusing errors.
