☑️ Ensure workload has valid label values
Labels are nothing more than custom key-value pairs that are attached to objects and are used to describe and manage different Kubernetes resources. If the labels do not follow Kubernetes label syntax requirements (see links below), they will not be applied properly.
info
Labels' keys and values are case-sensitive!
Targeted objects by this rule (types of kind): Deployment / Pod / DaemonSet / StatefulSet / ReplicaSet / CronJob / Job
Complexity: medium (What does this mean?)
Policy as code identifier: WORKLOAD_INVALID_LABELS_VALUE
This rule will fail
If one of the keys under labels contains an invalid value
metadata:
labels:
on-call: yoda@datree.io
Rule output in the CLI
$ datree test *.yaml
>> File: failExample.yaml
❌ Ensure workload has valid label values [1 occurrence]
💡 Incorrect value for key(s) under `labels` - the vales syntax is not valid so the Kubernetes engine will not accept it
How to fix this failure
Use valid values only (see links below for valid syntax)

labels:
on-call: yoda-at-datree.io
