Debug a Kubernetes Operator

What's the fastest way to debug a Kubernetes operator? Learn why inspecting the custom resource is often more direct than sifting through endless pod logs.

#1about 6 minutes

How Kubernetes operators manage application state

Operators extend Kubernetes with custom resources and use a reconciliation loop to ensure an application's current state matches its desired configuration.

#2about 10 minutes

Debugging a resource association error in an operator

A misconfigured resource reference in the YAML manifest prevents Kibana from starting, which is diagnosed using `kubectl describe` to find the association error.

#3about 7 minutes

Troubleshooting persistent volume claim storage issues

Pods stuck in a pending state are traced back to an invalid storage class in the persistent volume claim, requiring a recreation of the stateful set to fix.

#4about 8 minutes

Customizing operators and comparing them to Helm charts
