Some libraries require you to use string pointers or custom objects for some input parameters, notable examples are Pulumi and AWS CDK. If we only need to provide some static value for it can be annoying to use.

When writing a custom Kubernetes operator using operator-sdk we might want to change the fields are show when running kubectl get
:
$ kubectl get example
NAME AGE
demo 4h20m
To do so, we'll need to add the additionalPrinterColumns field the the CustomResourceDefinition, but since we are using operator-sdk to take care of this, we'll need to use some annotations in the resource definition file.

When creating a new API resource using the operator-sdk we can use the namespaced flag to make it Namespaced:
$ operator-sdk create api --group group \
--version v1 \
--kind Example \
--resource \
--controller
Or in the cluster scope:
$ operator-sdk create api --group group \
--version v1 \
--kind Example \
--resource \
--controller \
--namespaced=false
Maybe because we forgot to add the flag or because we have changed our mind, we don't need delete the object to change the scope of it, let's see how.
