Labels are used as an important source of metadata describing objects in various ways
|
|
or triggering other functionality. Labels are also a very basic concept and should be
|
|
used throughout Kubernetes. This policy performs a simple mutation which adds a label
|
|
`color=orange` to Pods, Services, ConfigMaps, and Secrets.

The ndots value controls where DNS lookups are first performed in a cluster
|
|
and needs to be set to a lower value than the default of 5 in some cases.
|
|
This policy mutates all Pods to add the ndots option with a value of 1.
