Kubernetes Deployment Monitoring Guide

This page is targeted at engineers looking for platform-specific guidance for monitoring Kubernetes rollouts, capturing deployment evidence, and correlating incidents with cluster events.

What is Kubernetes deployment monitoring​

It is capturing rollout events, probe failures, and cluster-level telemetry to determine whether a deploy reached a healthy state and whether it coincides with observed incidents.

Why this problem happens​

  • Missing deployment annotations
  • Probe misconfigurations leading to false positives
  • Image pull or registry permissions causing rollouts to fail

How engineers debug this​

  1. Inspect rollout and pod events using kubectl.
  2. Correlate pod restarts and OOMs with the deploy timestamp.
  3. Check image digest and registry access patterns.

Best practices​

  • Add deployment annotations with release id and artifact digest.
  • Automate canaries and monitor their health closely.

Tools that help​

OctoLaunch matches Kubernetes events with CI artifacts and incidents, enabling a timeline-centric view during investigations.

FAQ​

  • Q: Where should I place deployment annotations?
    • A: Annotate the Deployment and the Pod templates with release-id and artifact digest.
  • Q: How do I debug image pull failures?
    • A: Check node-level events and registry permissions logs.
