Using 'Running' will list active Pods, not pending ones.

The field-selector filters Pods by their phase. 'Pending' shows Pods waiting to start.

Common Mistakes

Using 'state' or 'condition' causes no output or errors.

The correct JSON path key for Pod lifecycle state is 'phase'.

💡 Hint

Common Mistakes

Using Pending or Failed will not show desired Pod states.

This command filters Pods that are either Running or have Succeeded.

5fill in blank

Fill all three blanks to create a command that watches Pods entering Running state with a label.

Kubernetes

kubectl get pods -l app=[1] --field-selector status.phase=[2] --watch=[3]

Drag options to blanks, or click blank then click option'
